    _________________________
    INTRODUCTION
    This case is one of several coordinated suits in which the
    plaintiffs allege talcum powder products manufactured by Johnson
    & Johnson and Johnson & Johnson Consumer Inc. (JJCI;
    collectively, defendants) caused them to develop ovarian cancer. In
    July and August 2017, bellwether plaintiff Eva Echeverria’s case
    was tried to a jury on a single claim of negligent failure to warn.
    The jury returned a verdict in Echeverria’s favor against both
    defendants, awarding compensatory damages of $68 million against
    Johnson & Johnson and $2 million against JJCI. The jury awarded
    punitive damages of $340 million against Johnson & Johnson and
    $7 million against JJCI.1 Defendants filed motions for judgment
    notwithstanding the verdict (JNOV) as to liability and punitive
    damages, as well as a joint motion for a new trial. The trial court
    granted the motions. Both sides have appealed.
    1     Echeverria died in September 2017. Her daughter, Elisha
    Echeverria, acting as trustee for the 2017 Eva Elaine Echeverria
    Living Trust, was substituted as plaintiff in October 2017.
    2
    We affirm the JNOV in favor of Johnson & Johnson, but
    partially reverse as to JJCI. To establish her negligence claim,
    Echeverria was required to prove each defendant had a legal duty
    to warn consumers about hazards inherent in their talc-based
    products; they breached that duty; and the breach caused
    Echeverria’s injury. The causation element required evidence that
    talc-based products not only cause ovarian cancer in general
    (general causation), but also that defendants’ products caused
    Echeverria’s ovarian cancer in particular (specific causation). We
    conclude there was no substantial evidence to support a finding of
    liability as to Johnson & Johnson, a parent company that stopped
    manufacturing Johnson’s Baby Powder in 1967, several years before
    there were any investigations or studies about a link between
    genital talc use and ovarian cancer. The evidence also failed to
    support a finding of malice as required for a punitive damages
    award, and we affirm the JNOV in favor of JJCI on that ground.
    We conclude there was substantial evidence to support the jury’s
    other findings as to JJCI. However, we must apply a different
    standard of review when evaluating the trial court order granting
    JJCI’s motion for a new trial. We determine the causation evidence
    was in significant conflict and would have supported a defense
    verdict. We therefore reverse the JNOV in favor of JJCI as to
    liability, but affirm the trial court order granting JCCI’s motion for
    a new trial.
    FACTUAL AND PROCEDURAL BACKGROUND
    General Background
    Plaintiff Eva Echeverria began using Johnson’s Baby Powder
    as a feminine hygiene product in 1965, when she was 11 years old.
    She continued using the product two to three times each day,
    applying it to her genital area, underwear, and sanitary napkins,
    until 2016. She also briefly used the product “Shower to Shower.”
    3
    In 2007, Echeverria was diagnosed with invasive, serous, high-
    grade ovarian cancer.
    Johnson & Johnson manufactured Johnson’s Baby Powder
    from 1893 until 1967. In 1967, JJCI began manufacturing the
    product. JJCI is a wholly owned subsidiary of Johnson & Johnson.
    Investigations of a Link Between Talc and Ovarian Cancer
    in the Scientific, Medical, and Regulatory Communities
    According to Echeverria’s evidence at trial, the first
    epidemiological study to investigate a link between talc and ovarian
    cancer was published in 1982. In the decades that followed,
    researchers published over 30 additional epidemiological studies
    exploring whether there is an association between talc use and
    ovarian cancer. The parties’ experts offered competing trial
    testimony about the validity, significance, and proper interpretation
    of these studies.2
    Other scientific studies have hypothesized that talc causes
    ovarian cancer by creating inflammation in the ovaries. Studies
    have concluded talc can migrate from the vagina into the peritoneal
    cavity, where the ovaries are located. Experts for both sides
    testified talc causes inflammation. Studies have found chronic
    inflammation plays a role in the development of some types of
    cancer. Studies referenced at trial have also indicated increased
    inflammation may be linked to ovarian cancer. However, no
    2      The parties’ appellate briefing includes citations to documents
    that were identified at trial, but not admitted, such as complete
    copies of scientific publications. “It is axiomatic that in reviewing
    the liability aspect of a judgment based on a jury verdict, we may
    not review exhibits identified, but not admitted at trial.” (Frank v.
    County of Los Angeles (2007) 
    149 Cal. App. 4th 805
    , 815.)
    4
    published studies, regulatory agencies, or scientific organizations
    have concluded talc-based inflammation causes ovarian cancer.
    The World Health Organization International Agency for
    Research on Cancer (IARC) evaluates the carcinogenicity of
    different agents. In 2006, the IARC evaluated talc. The agency
    characterized perineal use of talc as possibly carcinogenic to
    humans, giving it a “2B” rating. This rating reflected a
    determination that there was “limited evidence” of carcinogenicity
    in humans and in experimental animals. The limited evidence
    determination meant: “A possible association has been observed
    between exposure to talc and ovarian cancer for which a causal
    interpretation is considered by the working group to be credible, but
    chance, bias, and confounding could not be ruled out with
    reasonable confidence.”
    Some medical and scientific organizations have publicly
    identified genital talc use to be a risk factor for ovarian cancer,
    while others have not. In 2014 and 2015, the National Cancer
    Institute identified perineal talc use as a risk factor for ovarian
    cancer; in 2017, it indicated the weight of the evidence does not
    support an association between perineal talc exposure and an
    increased risk of ovarian cancer.
    Defendants’ Response to Ongoing Questions Regarding a
    Link Between Talc and Ovarian Cancer
    The evidence at trial included a series of documents from
    defendants’ files regarding talc and Johnson’s Baby Powder.
    Several of the documents lacked identified authors or other
    information to distinguish whether they were generated by Johnson
    & Johnson or JJCI. Other documents reflected communications
    between or among employees of both companies.
    5
    In 1964, W.H. Ashton, a Johnson & Johnson scientist, penned
    a memo to the file regarding plans for a test of a baby powder
    product composed of cornstarch, rather than talc. The goal was to
    “determine a preference rating” of Johnson’s Baby Powder
    compared to another product. The memo suggested “Dry Flo,” “a
    low substituted A1 salt of mildly treated cornstarch,” could be used
    as a potential additive. Although other potential additives were
    identified, Ashton wrote Dry Flo “has a very appealing tone because
    it would open the door to a merchandising advantage which could
    refer to an all starch product . . . .” The memo reported: “Since the
    meeting, Ashton established the largest commercial uses of Dry Flo
    are in Vitamin A manufacture . . . and as a condom lubricant where
    it replaced talc because it was found to be absorbed safely in the
    vagina whereas, of course, talc was not.”
    A 1975 letter on “Johnson & Johnson” letterhead bore the
    subject line “Talc in the Ovaries.” A handwritten note on the
    document suggested a Johnson & Johnson scientist’s contact with a
    cancer research institute may have provided “the opening to put us
    on notice re: the talc/ovary problem.”
    Documents from 1986 and 1992 acknowledged genital talc use
    had been “implicated” or “linked” to ovarian cancer. The 1986
    document expressed a continuing belief that talcum powder
    products were safe. It referenced a Cosmetics, Toiletries, and
    Fragrance Association (CTFA) sponsored animal study concluding
    talc does not migrate, and also cited the company’s “extensive
    experience in use.” Still, the documents recognized that cancer
    concerns, risks from inhalation, and a move among health
    professionals to discourage use of talc-based powders on babies, all
    posed a potential obstacle to sales.
    Documents from 1993 to 1995 reflected defendants’
    awareness of epidemiological studies about talc use and ovarian
    6
    cancer, their creation of a “Worldwide Talc Steering Committee,”
    their monitoring of scientific studies and regulatory action on talc,
    and their strategies to respond to adverse press or media inquiries
    about talc safety issues. For example, a 1994 document prepared by
    a JJCI employee proposed answers to questions about a causal link
    between talc and cancer, and about two specific epidemiological
    studies. The proposed answers stated one study did not show a
    causal relationship between talc and ovarian cancer, while the
    other study found a higher incidence of ovarian cancer in women
    who routinely used talc, yet ultimately concluded talc was unlikely
    to be the cause of the majority of epithelial ovarian cancers. In
    response to the question of whether cosmetic talc use could lead to
    ovarian cancer, the document offered the answer: “Studies in
    animals have shown that talc does not migrate from the vagina to
    the ovaries. In conventional animal dosing studies, there is no
    evidence of ovarian cancer. Based on the available scientific data,
    no cause and effect relationship has been established showing that
    the use of talc can cause ovarian cancer.”
    A 1995 memo on “Johnson & Johnson Consumer Products
    Worldwide” letterhead, authored by “John Hopkins of Johnson &
    Johnson,” addressed methods for responding to “adverse press and
    media issues around talc.” The memo laid out three potential
    strategies, ranging from “do nothing,” to a more “pro-active”
    strategy. Hopkins reported they had been taking the first
    approach: “We do not cause waves and we give no further publicity
    to adverse comments.” Hopkins recommended a middle approach
    that would entail “responding to articles in the press, possibly
    including medical journals where we believe we can influence
    future behaviors and comment.” A note from a vice president of
    research and development suggested “it might be worthwhile to
    have some effort” in the “proactive” strategy as well.
    7
    In 1997, an outside consultant wrote to a JJCI employee,
    offering criticisms of CTFA responses to claims of a link between
    talc and ovarian cancer. The consultant noted “several
    investigators have independently reported talc particles in ovarian
    tissue” and it was inaccurate to state that studies had failed to
    demonstrate “any real association” between hygienic talc and
    ovarian cancer. The letter pointed out that at least nine studies
    published in the open literature had shown a statistically
    significant association between the two. The consultant cautioned
    that denying the association “risks that the talc industry will be
    perceived by the public like it perceives the cigarette industry:
    denying the obvious in the face of all evidence to the contrary. This
    would be a particularly tragic misperception in view of the fact that
    the industry does have powerful, valid arguments to support its
    position.” He suggested the better arguments were that the study
    results were “ambiguous, inconsistent, contradictory and therefore
    inconclusive . . . .” He concluded the letter: “I realize that CTFA is
    not J&J. However, I believe that a defeat or embarrassment of
    CTFA also negatively affects J&J to some extent.”
    In 2002, a director of product safety at Luzenac, defendants’
    talc supplier in the United States, sent a document to Ashton
    reporting: “We’ve been successful thus far in fending off the
    [National Toxicology Program (NTP)] classification of talc as being
    a potential human carcinogen. But we must also keep an eye out
    for IARC. If they decide to re-review the status of talc because of all
    the ovarian epidemiology studies that have been published since
    1986, IARC can surprise us all and decide to list ‘talc’ as a potential
    human carcinogen. . . . Their threshold for required medical
    evidence is predictably quite minimal. You might want to counsel
    your management on this potential (and not to be too complacent
    about the status of talc).”
    8
    In 2004, the same Luzenac employee forwarded Ashton a
    study published earlier that year. He indicated the study “offers
    some compelling evidence in support of the ‘migration’ hypothesis.
    Combine this ‘evidence’ with the theory that talc deposition on the
    ovarian epithelium initiates epithelium inflammation—which leads
    to epithelium carcinogenesis—and you have a potential formula for
    NTP classifying talc as a causative agent in ovarian cancer.” In
    2006, Luzenac began including the IARC 2B classification in its talc
    material data safety sheets (MSDS).
    Internal documents and e-mails from 2005 and 2006 reflected
    discussions among several individuals, including JJCI employees in
    the United States and Johnson & Johnson “regulatory” and
    “research” employees in Europe, about NTP and IARC evaluations
    of talc as a potential carcinogen. The e-mails referenced a project to
    “defend talc” and efforts to prevent a classification of talc as a
    carcinogen. They revealed the correspondents’ desire for certain
    “helpful” scientists to participate in the evaluations. The e-mails
    also discussed efforts to promote or develop studies or documents
    “that scientifically support the lack of a relationship of talc and
    ovarian cancer.”
    In 2016, the Food and Drug Administration (FDA) issued a
    request to JJCI for information on talc. The JJCI response noted
    that in 2014, the FDA reviewed the safety of talc and denied citizen
    petitions filed in 1994 and 2008. The “ ‘FDA did not find that the
    data submitted presented conclusive evidence of a causal
    association between talc use in the perineal area and ovarian
    cancer.’ ” According to the response, the FDA also reviewed “the
    toxicity literature from 1980 to 2008 and did not find enough
    additional support at that time for the types of warning labels
    proposed” in the citizen petitions.
    9
    The JJCI response summarized the company’s position: “At
    Johnson & Johnson Consumer Inc., our confidence in using talc is
    based on more than 100 years of safe use and more than 30 years of
    research by independent researchers, scientific review boards and
    global regulatory authorities. Various agencies and governmental
    bodies have examined whether talc is a carcinogen, and none have
    concluded that it is. The scientific literature, post-market
    experience, and expert opinion do not support the association of talc
    and ovarian cancer.”
    The Expert Testimony at Trial
    Echeverria offered the testimony of four experts:
    pharmacologist and toxicologist Dr. Laura Plunkett; epidemiologist
    Dr. Jack Siemiatycki; pathologist Dr. John Godleski; and
    Echeverria’s treating gynecologic oncologist, Dr. Annie Yessaian.
    There was extensive pretrial litigation on the admissibility of
    plaintiff’s proposed expert testimony, including a hearing pursuant
    to Sargon Enterprises, Inc. v. University of Southern California
    (2012) 
    55 Cal. 4th 747
    . The trial court ruled only Dr. Yessaian
    would be allowed to testify as to “specific causation,” i.e., offering an
    opinion that talc caused Echeverria’s ovarian cancer. The other
    experts whose testimony was not completely excluded were allowed
    to testify only about general causation, i.e., offering an opinion that
    talc in general may cause ovarian cancer. Dr. Godleski was also
    allowed to provide opinions based on his personal examination of
    Echeverria’s tissues.
    Defendants offered the testimony of Dr. Alan Andersen, a
    biophysicist and former high-level employee at the FDA and the
    Cosmetic Ingredient Review (CIR); Dr. Douglas Weed, an
    epidemiologist and medical doctor; Dr. Juan Felix, a gynecologic
    pathologist; and Dr. Cheryl Saenz, a gynecologic oncologist.
    10
    General Causation: Plaintiff’s Expert Testimony
    Dr. Laura Plunkett
    Dr. Plunkett is a former assistant professor of pharmacology
    and toxicology at the University of Arkansas. She is currently a
    consultant in the areas of toxicology, pharmacology, and human
    health risk assessment. Dr. Plunkett opined talc is toxic, it can
    migrate from the vagina to the ovaries, it can cause inflammation in
    human tissues, and chronic inflammation can cause ovarian cancer.
    Plunkett’s opinion that talc is toxic was based on animal studies
    and human and animal cell studies. Plunkett testified she cited
    hundreds of studies in her expert report, a few of which she
    highlighted in her testimony.
    For example, Plunkett described a 1984 study in which the
    injection of a talc solution near rat ovaries caused precancerous
    lesions in the rat’s tissues. Plunkett also relied on a 1993 NTP
    study showing rats exposed to airborne talc for two years—a
    lifetime—developed precancerous lesions and, in some cases,
    tumors. She noted “dozens” of earlier studies established “talc can
    cause inflammation at the site.”
    Plunkett also discussed two human cell studies. According to
    Plunkett, a 2007 study found talc produced neoplastic
    transformation in human ovarian cells.3 A 2009 study showed talc
    had effects in human cells, “as far as the type of genes it turns on
    and off,” that are similar to the effects observed with compounds
    known to cause cancer. Plunkett testified these studies supported
    her opinion that talc initiates an inflammatory response that leads
    3      Plunkett described “neoplastic” or “neoplasm”: “That means
    tumor. So transformation is a process where it takes a cell and
    where the cell is changing from a preneoplastic cell—or a normal
    cell to a preneoplastic cell, taking on the characteristics of a cell
    that could become a cancer cell and could form a tumor.”
    11
    to cancer. Her opinion that talc can migrate from the vagina to the
    upper genital tract and to the ovaries was based on five studies
    dating from the early 1960’s to the early 2000’s, each of which she
    described for the jury.
    Defendants tested and challenged Plunkett’s interpretation of
    these scientific studies on cross-examination. She acknowledged
    weaknesses and limitations in the studies, but still felt they
    provided useful information. She also admitted there were several
    studies that came to different conclusions about the role of chronic
    inflammation in the development of ovarian cancer and the effect of
    talc on the female genital system.
    Plunkett additionally based her opinion on her review of the
    epidemiological literature, including six meta-analyses showing a
    statistically significant increased risk between exposure to talc in
    the genital area and ovarian cancer. Plunkett explained that no
    single study could conclude talc causes cancer. Instead, she
    described each study as a piece of the causation puzzle.
    Having reviewed the scientific data, Plunkett opined that
    regular genital use of talc sets up a chronic inflammatory condition
    in the cells that causes them to change to precancerous cells. The
    precancerous cells eventually lead to tumor growth, metastasizing
    tumors, and “full-blown advanced stage ovarian cancer.” Plunkett
    also evaluated the Bradford Hill criteria, a framework for
    considering whether a substance causes a disease.4 She opined she
    4     The criteria are temporal relationship, strength of the
    association, dose-response relationship, replication of the finding,
    biological plausibility, consideration of alternative explanations,
    cessation of exposure, specificity of the association, and consistency
    with other knowledge. (Green et al., Reference Guide on
    Epidemiology in Reference Manual on Scientific Evidence (3d ed.
    2011) 549, 600 (hereafter, Reference Guide).) Epidemiologists use
    12
    had enough information relevant to the criteria to state, to a
    reasonable degree of scientific and professional certainty, that
    genital exposure to talc causes ovarian cancer.
    Dr. Jack Siemiatycki
    Dr. Siemiatycki is an epidemiologist and professor at the
    University of Montreal and McGill University. He has over 200
    peer-reviewed publications and numerous honors and awards for
    his work in epidemiology and biostatistics.
    Siemiatycki explained several epidemiological concepts to the
    jury. He informed the jury that “relative risk” is the risk of
    developing a disease among people exposed to a particular chemical
    agent or toxin, divided by the risk of developing the disease among
    those not exposed to the same agent. He offered an example: “So if
    the risk of cancer in the general population . . . is 4 percent in the
    general population but among a group of people with a certain
    environmental exposure it is 6 percent, the relative risk of cancer
    due to that environmental exposure would be 6 percent divided by 4
    percent equals 1.5.”
    Siemiatycki then elaborated: “[W]hen the risk is exactly the
    same among the exposed and the unexposed, then the relative risk
    will be 1. . . . The risk among the exposed is the same. . . . And that
    means the agent, whatever the exposure is, has no effect on the risk
    of developing the disease. . . . . If the relative risk is greater than 1,
    it means exposure to that agent increases the risk of developing the
    disease. If the relative risk is less than 1, so the risk among the
    these factors when considering whether a statistical association
    reflects a causal relationship. They “reflect criteria proposed by the
    U.S. Surgeon General in 1964 in assessing the relationship between
    smoking and lung cancer and expanded upon by Sir Austin
    Bradford Hill in 1965 . . . .” (Ibid., fns. omitted.)
    13
    exposed is less than the risk among the unexposed, it means that
    exposure to the agent prevents the disease.”
    Siemiatycki explained the related concepts of “confidence
    intervals” and “statistical significance.” Statistical significance
    concerns the question, “how solid is our belief that the relative risk
    that we observe in a study is really precise and accurate?”
    Statistical significance depends on a number of factors, including
    the size of the study. Siemiatycki provided the jury with an
    example in which a study estimated a relative risk of 1.2, with a
    95 percent probability that the true estimate is between 1.1 and 1.3.
    “That’s a pretty tight interval, and we call that a confidence
    interval. We call it a 95 percent confidence interval when we
    calculate it in such a way that it covers 95 percent of the underlying
    relative risks that are compatible with this estimate from this
    study.” If the results of a study have a confidence interval that
    includes relative risk numbers under 1—reflecting decreased risk—
    they are not statistically significant. In those cases, the results
    could be due to chance. However, Siemiatycki disagreed that a
    study with a nonstatistically significant result must be disregarded.
    Such studies still contain information that may be useful when
    combined with evidence from other studies.
    Siemiatycki chaired the 2006 IARC working group on talc.
    The group concluded the association between perineal talc use and
    ovarian cancer could have other possible explanations. The
    available evidence was not strong enough to exclude chance, bias,
    and confounding—the presence of another factor that may be
    causing the disease—as explanations for the association that had
    been observed between talc and ovarian cancer.
    Siemiatycki’s current opinion is that it is more likely than not
    genital talc use can cause ovarian cancer. His change of opinion
    was based in part on a 2013 study which, he testified, showed a
    14
    dose-response pattern—increased risk with increased exposure—
    that was missing in earlier studies. Siemiatycki opined the 2013
    study, as well as studies published in 2015 and 2016, led him to
    conclude the statistical evidence associating genital talc use and
    ovarian cancer is now much stronger than it was 10 years earlier.
    Siemiatycki also conducted a meta-analysis using existing
    talc literature to develop an opinion for the litigation. His analysis
    of 28 or 29 studies led him to believe there is a “very, very strong
    statistical association between use of talc and ovarian cancer.” The
    analysis resulted in a relative risk of 1.28, with a confidence
    interval of 1.18 to 1.38, rendering the results highly statistically
    significant. In other words, Siemiatycki found a 28 percent greater
    risk of ovarian cancer among women who used talc compared to
    women who had not used talc.
    Siemiatycki evaluated the Hill factors and concluded they
    support an opinion that there is a causal relationship between
    genital talc use and ovarian cancer. He testified that for as many
    as half of the known carcinogens for which there is epidemiologic
    data, the data show relative risk estimates less than 2.0. Like
    Plunkett, Siemiatycki testified epidemiologists typically do not
    write articles stating “this causes that.” He explained “that sort of
    communication tends to come from authoritative agencies who have
    the capacity to integrate the viewpoints of multiple experts and,
    preferably, multiple experts from multiple disciplines.”
    General Causation: Defendants’ Expert Testimony
    Dr. Alan Andersen
    Dr. Andersen is a former director of the CIR. He described
    the CIR as an independent review group, but also admitted an
    industry trade group is the CIR’s sole funder. Andersen testified
    the group’s mission is to review and assess the safety of ingredients
    15
    in an “open, unbiased, and expert manner,” and to publish the
    results in peer-reviewed scientific literature. In 2011, a CIR panel
    began a review of the safety of talc and concluded, in 2013, that talc
    is safe.
    The CIR panel determined available data “did not reliably
    demonstrate” talc could migrate from the perineal area into the
    ovaries. The panel concluded the epidemiological data did not
    consistently reveal statistically significant positive associations
    between talc use and ovarian cancer; there were uniformly small
    risk ratio estimates; and other plausible alternative explanations of
    the association had not been ruled out. The panel did not see a
    consistent dose-response pattern reflected in the available
    literature. The panel also concluded there was no plausible
    biological mechanism to explain how genital talc use could cause
    ovarian cancer. It found a “lack of credible defensible evidence of
    carcinogenicity from the results of epidemiological studies of
    occupational exposures and animal bioassays.” The panel
    determined the available cellular studies were “unremarkable,”
    meaning there were no adverse cellular effects relating to talc.
    Dr. Douglas Weed
    Dr. Weed, medical doctor and epidemiologist, is a former chief
    of the office of preventive oncology at the National Cancer Institute,
    and currently a consultant. Based on his review of the scientific
    literature and the Hill criteria, Weed opined it has not been
    established that talc use causes ovarian cancer. In his evaluation of
    the epidemiological literature, he concluded the published cohort
    studies show no association between genital talc use and ovarian
    cancer. The case-control studies establish only a “weak” association
    16
    reflected in a relative risk estimate of 1.3.5 Weed opined the
    studies do not establish a dose-response pattern.
    Weed further testified that some studies call into question the
    proposed biological mechanism of migrating talc particles causing
    inflammation. For example, although one would expect that women
    who used genital talc but had tubal ligation or hysterectomies
    would experience a reduced risk of ovarian cancer, Weed testified
    studies reveal “a mix of results.” Similarly, studies show no
    uniformly reduced risk of ovarian cancer in women who use
    medications that reduce inflammation. Weed also indicated studies
    have not established genital talc use increases the risk of other
    kinds of cancer in the female genital tract.
    Pathology: Plaintiff’s Expert Testimony
    Dr. John Godleski
    Dr. Godleski is a professor of pathology, recently retired from
    Harvard Medical School and the Harvard School of Public Health,
    where he continues to consult on research programs. He has close
    to 150 peer-reviewed publications, including a case report regarding
    the presence of talc particles in the lymph nodes of a woman
    diagnosed with ovarian cancer who had used genital talc for over 30
    years.
    5     Case-control and cohort studies are two types of
    epidemiological observational studies. In case control studies,
    researchers take two groups of people, one with the disease and one
    without, and both groups are asked about exposures they have had.
    In cohort studies, researchers study two groups, one whose
    participants have been exposed to the studied agent and an
    unexposed group. Researchers then observe and measure the
    incidence of the disease in both groups. (Reference 
    Guide, supra
    , at
    pp. 556-559.)
    17
    Godleski examined slides of Echeverria’s gynecologic tissue,
    using electron microscopy and x-ray analysis to identify talc
    particles. He found 11 talc particles and fibers in the examined
    tissues—eight particles of talc in ovarian tissue, and three talc
    particles in pelvic peritoneum and omentum tissue. Godleski
    opined that finding 11 particles in a small sample indicated there
    was a “substantial burden of talc” in Echeverria’s tissue. He was
    “convinced” the particles were present as the result of perineal talc
    use.
    Godleski admitted his expert reports submitted before trial
    did not mention that he observed inflammation in Echeverria’s
    tissues. However, at trial Godleski testified he observed a talc
    particle, and other particles with characteristics of talc, near or
    “involved with” macrophages, which are cells that are signals of an
    inflammatory reaction. Godleski believed this suggested the
    occurrence of a chronic inflammatory process. The talc particle
    involved with a macrophage was from a slide of Echeverria’s
    ovarian tissue. The other particles and cells were from a slide of
    Echeverria’s pelvic peritoneum tissue. Godleski testified “to a
    reasonable degree of medical certainty that the presence of talc
    found in a woman’s ovarian tissue can be contributory evidence for
    a causal link between the presence of talc and the development of a
    woman’s ovarian cancer.”
    Pathology: Defendants’ Expert Testimony
    Dr. Juan Felix
    Dr. Felix is the former director of gynecologic pathology at the
    University of Southern California (USC) Keck Medical Center. He
    is currently a professor and the director of anatomic pathology at
    the Medical College of Wisconsin. Felix testified that 75 to
    80 percent of cases of ovarian cancer have an unknown cause. He
    18
    also testified exposure to talc “guarantees” there will be chronic
    inflammation in the body, and talc in a woman’s peritoneal cavity
    will produce inflammation and chronic toxicity. However, he opined
    the inflammation would take the form of adhesions and
    granulomas, neither of which causes ovarian cancer.
    Felix reviewed Echeverria’s tissue slides and found no
    inflammation or evidence of the inflammatory reaction Godleski
    described. Felix testified that macrophages do not cause or
    contribute to the growth of ovarian cancer. He has seen hundreds
    of cases in which inflammation caused cancer and, in those cases,
    the inflammation was everywhere, not hidden or in an isolated
    area. He testified the presence of a tumor would not obscure the
    presence of talc-induced inflammation.
    Specific Causation: Plaintiff’s Expert
    Dr. Annie Yessaian
    Dr. Yessaian is a double board-certified gynecologic oncologist
    at USC. She handles over 150 surgeries each year and also teaches
    and supervises medical students. Yessaian began treating
    Echeverria in 2007.
    Yessaian conducted a “differential diagnosis” to form an
    opinion for the litigation about the cause of Echeverria’s cancer.6
    6     “Differential diagnosis, or differential etiology, is a standard
    scientific technique of identifying the cause of a medical problem by
    eliminating the likely causes until the most probable one is
    isolated. . . . [Citation.] . . . [¶] The first step in the diagnostic
    process is to compile a comprehensive list of hypotheses that might
    explain the set of salient clinical findings under consideration.
    [Citation.] The issue at this point in the process is which of the
    competing causes are generally capable of causing the patient’s
    symptoms or mortality. . . . [¶] After the expert rules in all of the
    potential hypotheses that might explain a patient’s symptoms, he or
    19
    Yessaian considered several “protective factors,” which “are very
    well known and established to reduce a woman’s risk of developing
    ovarian cancer.” These were parity—how many children a woman
    has delivered to term, use of oral contraception, bilateral tubal
    ligation, and breastfeeding. Echeverria had one child, so Yessaian
    considered this “a factor.” Echeverria used oral contraception very
    briefly, breastfed her daughter very briefly, and did not have tubal
    ligation.
    Yessaian considered genital talcum powder. She took note
    that Echeverria used talcum powder two or three times a day for
    over 40 years, resulting in over 30,000 genital applications in her
    lifetime. Yessaian reviewed migration studies establishing there is
    a biologically plausible way for talc to go from the external
    environment to the peritoneal cavity. She looked at “other
    evidence” relating to a mechanism of “talc sitting in the peritoneal
    cavity” and “participating in that whole cascade of process from
    inflammation to malignant transformation to leading to cancer.”
    Yessaian did not have specific evidence of this mechanism taking
    place in Echeverria. However, she considered Godleski’s findings
    that talc was present in Echeverria’s ovary, omentum, and
    peritoneal cavity, all places where cancerous tumors were found.
    Yessaian also considered numerous epidemiological studies.
    At trial, she discussed studies that found 20, 40 and 60 percent
    increases in the risk of serous ovarian cancer in women exposed to
    talc. She also indicated she relied on four studies with odds ratios
    she must then engage in a process of elimination, eliminating
    hypotheses on the basis of a continuing examination of the evidence
    so as to reach a conclusion as to the most likely cause of the
    findings in that particular case.” (Clausen v. M/V New Carissa (9th
    Cir. 2003)

    , 1057-1058.)
    20
    or relative risk estimates above 2.0.7 A 1982 study showed an odds
    ratio of 3.28, while a 1992 study resulted in an odds ratio of 4.8.8 A
    1999 study showed an overall odds ratio of 2.15, with a stratified
    result of 1.70 for serous ovarian cancer. A 2009 study showed an
    overall odds ratio of 2.08, and a 1.70 estimate for the serous
    subtype. Yessaian believed the results of the 2009 study suggested
    Echeverria was at an even higher risk than the overall risk
    estimate reflected in the study, given the extent of her talc use. All
    four studies had statistically significant results. Yessaian further
    testified about four studies that provided evidence of dose response.
    Yessaian also “evaluated . . . 13 factors that could have an
    implication in ovarian cancer in general.” She considered genetic
    mutation as a potential cause and ruled it out. During the course of
    treating Echeverria, Yessaian ordered genetic testing on multiple
    occasions. The testing revealed no abnormalities in the mismatch
    7      Before trial, the court ruled Yessaian’s testimony would be
    allowed, provided she could opine based solely on studies showing
    risk estimates greater than 2.0. As discussed in greater detail
    below, the court relied on cases concluding only epidemiological
    studies with relative risk estimates greater than 2.0 (“doubling the
    risk”) are useful to the jury as support for a specific causation
    opinion. These cases reason “a relative risk of 2.0 implies a 50%
    probability that the agent at issue was responsible for a particular
    individual’s disease. This means that a relative risk that is greater
    than 2.0 permits the conclusion that the agent was more likely than
    not responsible for a particular individual’s disease. [Citation.]”

    , 893.)
    8     In case-control studies, the association between the exposure
    to an agent and the disease is reflected as an odds ratio rather than
    as a relative risk. (Reference

    repair genes known to increase the risk of ovarian cancer and no
    clinically significant gene mutations.
    Yessaian considered and ruled out fertility medications and
    hormone replacement therapy as Echeverria had not used either
    one. She considered endometriosis and polycystic ovarian syndrome
    and ruled both out; Echeverria did not suffer from either condition.
    Yessaian considered tobacco and alcohol use since Echeverria had
    used both for a short time. Yessaian ruled out tobacco, indicating
    the data on tobacco and ovarian cancer are “inconclusive at best,
    especially if you look at for serous.” Yessaian also ruled out alcohol
    use, concluding Echeverria’s alcohol consumption was not
    significant enough to cause her ovarian cancer.
    Yessaian considered family history. Echeverria’s mother had
    pancreatic cancer. Her aunt had colon cancer. No family members
    had ovarian or breast cancer. Yessaian noted the aunt with colon
    cancer was diagnosed in her 80’s and genetic testing had
    established Echeverria’s cancer was not genetically related.
    Yessaian thus ruled out family history of cancer.
    Yessaian considered Echeverria’s age. She believed 52 to be
    an average age for ovarian cancer incidence and therefore not a
    likely cause.
    She considered menarche, the age at which Echeverria had
    her first menstrual period, and menopause. Yessaian explained:
    “The idea is if a woman gets her periods so, so young and then gets
    her menopause so, so late, she has all these long, long years of
    ovulation. One of the theories is that with every ovulation the
    surface of the ovary has an injury. And when the body tries to
    repair that injury—cancer is kind of like a repair gone wrong. . . .
    So that’s why the more ovulations you had, like early—you know,
    they start their periods at nine and they are menopausal at like 55
    and beyond, they’ve had so much more ovulations, more chances of
    22
    damage to the surface, more damage or repair process that could go
    off, so that’s why. And [Echeverria] was so average in her age of
    menarche and also her age at menopause. She was menopausal
    before I saw her.” Yessaian thus ruled out menarche and
    menopause, or the number of ovulatory cycles, as a cause.
    Yessaian considered and ruled out Echeverria’s obesity. She
    explained obesity is a standard risk factor for uterine cancer: “[T]he
    more estrogen you have through these cells producing more
    estrogen in the fatty tissue, the more likely you are to get uterine
    cancer and breast cancer. The data on these two are very, very
    solid.” Yessaian testified there is no similar “solid evidence”
    identifying obesity as a risk factor for ovarian cancer. Yessaian had
    reviewed the available literature and found no correlation between
    obesity and serous ovarian cancer.
    Yessaian thus concluded “talc was more probable than not the
    causing agent in Ms. Echeverria’s developing high-grade serous
    ovarian cancer,” and that it is more probable than not that but for
    her use of talc, she would not have developed the cancer. Yessaian
    testified her opinion was not based on a single study, factor, or
    element. Rather it was the “totality of all the evidence and the
    factors” she considered.
    On cross-examination, Yessaian admitted she did not have
    any evidence there was inflammation in Echeverria’s ovarian
    tissue. If Echeverria had been over 60 years old, Yessaian would
    have attributed the cancer to aging and would have concluded it
    was more than 50 percent likely that advancing age and the
    corresponding accumulation of “genetic hits” caused the cancer.
    Since Echeverria was younger—52 when diagnosed—Yessaian
    found age less likely to be the cause. Yessaian admitted no one
    could completely rule out age as a contributing factor but she was
    trying to figure out “which factor stands out.”
    23
    As to a high number of ovulatory cycles, Yessaian opined it
    was not an “independent risk factor for postmenopausal ovarian
    cancer.” She testified she could not rule out the number of
    ovulatory cycles “as a hundred percent, but it more likely than not
    was not a factor.”
    Yessaian agreed that in general terms for ovarian cancer, as
    well as other cancers, it might be true that the “biggest cause” is
    “unknown etiology.” She also agreed that “unknown etiology” could
    be a cause of Echeverria’s ovarian cancer, but opined that was “less
    probable than not.” She explained the statement “the leading cause
    of cancer is an unknown etiology” applies to everyone and ovarian
    cancer in general. She distinguished Echeverria’s case: “Not Ms.
    Echeverria’s specific serous and with everything else included in
    her history, having ruled out genetics, and we’ve been talking about
    this whole talc and migration and use and et cetera. That
    statement holds true as a blanket general, not for this particular—
    Ms. Echeverria’s case.” She later elaborated that she had “studied
    all the details in [Echeverria’s] particular case. And when you’re
    putting an etiology of all cancers, that’s for everybody else, the
    population of the world in general. We’re talking about how we
    evaluated this patient’s case in detail and studied all other factors
    involved. She’s not a generic part of the population. I’m talking
    about a case that—a patient that has been studied and evaluated in
    [detail].”
    Defense counsel asked if Yessaian’s differential diagnosis
    started with the assumption that it was possible to find a cause of
    the cancer without considering the possibility that an unknown risk
    factor caused the cancer, or that it developed spontaneously.
    Yessaian answered: “I objectively evaluated all risk factors to the
    best of my knowledge and ability . . . . I did not have any
    preconceived conclusion for which I wanted to fit my . . . workup
    24
    . . . . I always assume unknown is part of what I do. I want to
    make sure—can I find something known? Because I look for what I
    know. I look for known. And if I don’t find something known, then
    I say, okay, it’s unknown. I mean there’s no publication that says
    let’s look at unknown—the role of unknown. We look at what we
    know. And we cannot find something we know, then, okay, sorry,
    we tried. It’s unknown.”
    Counsel asked for the basis for Yessaian’s testimony that it is
    less than 50 percent likely that the cause of Echeverria’s cancer is
    unknown. Yessaian answered: “At the risk of sounding redundant
    and repetitive, all the risk factors that I included, ruling in, ruling
    out the fact about her talc exposure, the epidemiologic data that
    support, the total evidence that I provided in my report and my
    knowledge of her . . . . Because I’ve studied Ms. Echeverria’s case
    specifics. I looked at all the risk factors that applied to her. I’ve
    looked at the protective factors that could apply to her, the talc
    exposure, the epidemiology, . . . the migration, all of that put
    together. I cannot do the same assessment for every patient out
    there in the general population. So not all patients with cancer get
    that dissection of possible etiology.”
    Specific Causation: Defendants’ Expert
    Dr. Cheryl Saenz
    Dr. Saenz is a gynecologic oncologist and clinical professor at
    the University of California, San Diego. Saenz opined perineal use
    of talc does not contribute to the development of ovarian cancer.
    She based her opinion on her over 20 years of clinical experience
    treating thousands of women with ovarian cancer, a review of the
    literature on the topic, and the absence of evidence “that talc is a
    consistently credible scientific cause of ovarian cancer.” Saenz
    testified several factors increased Echeverria’s risk for developing
    25
    ovarian cancer: her family history of cancer, even though her
    family members had different kinds of cancer; her morbid obesity;
    the fact that she had her first child late, at 36 years old; and her
    early menarche at age 11.
    Saenz disagreed with Yessaian’s opinion that vaginal talc use
    was more likely than not the cause of Echeverria’s cancer. She
    testified ovarian cancer is multifactorial and there is no way for her
    to say exactly what causes a patient to develop the disease. Saenz
    does not consider unknown etiology to be a risk factor, instead “it’s
    a fact. We don’t know what causes the majority of ovarian cancers
    . . . over 50 percent.” Saenz opined it is more likely than not talc
    had nothing to do with Echeverria developing ovarian cancer. She
    has operated on thousands of women with ovarian cancer and has
    never seen inflammation in any of her ovarian cancer patients.
    Saenz critiqued Yessaian’s method of considering
    epidemiological studies. She explained the epidemiological
    “literature is being published to try and determine whether or not
    there are certain associations, to try and determine whether or not
    there are certain relationships. It’s not meant to be a mathematical
    model that you can then just plug your patient into and do a
    calculation of her individual risk.”
    Saenz also testified specifically about a 2016 study both she
    and Yessaian had cited in their reports. Saenz testified the study
    showed a relative risk estimate of 1.33 for serous invasive ovarian
    cancer, for women who, like Echeverria, were postmenopausal at
    the time of diagnosis and used talc more than 24 years. Yet, for
    women who, also like Echeverria, were postmenopausal at the time
    of diagnosis, did not use hormone replacement therapy, and used
    talc more than 24 years, the study showed a relative risk of 1,
    26
    indicating no increased risk.9 Both results had confidence intervals
    rendering them not statistically significant. Saenz continued: “So
    in my opinion, again, I do not think you should ever use literature
    to see what happened with one individual patient. But if you’re
    going to pull the numbers that apply to Ms. Echeverria, this paper
    says that she is not at an increased risk of developing ovarian
    cancer based on her years of talc use.”
    Jury Verdict and Posttrial Motions
    The jury returned a verdict finding both defendants liable for
    negligent failure to warn. The jury awarded Echeverria a total of
    $70 million in compensatory damages; $68 million as to Johnson &
    Johnson and $2 million as to JJCI. The jury awarded $347 million
    in punitive damages; $340 million against Johnson & Johnson, and
    $7 million against JJCI. Defendants filed separate motions for
    JNOV and a joint motion for a new trial. The trial court granted
    the three motions.
    DISCUSSION
    I.    Judgment Notwithstanding the Verdict
    A.     Standard of Review
    “ ‘ “A motion for judgment notwithstanding the verdict may be
    granted only if it appears from the evidence, viewed in the light
    most favorable to the party securing the verdict, that there is no
    substantial evidence in support. [Citation.] [¶] . . . As in the trial
    court, the standard of review [on appeal] is whether any substantial

    , 192.) We, like the trial court, may not reweigh the

    evidence or judge the credibility of witnesses. “ ‘ “ ‘If the evidence is
    conflicting or if several reasonable inferences may be drawn, the
    motion for judgment notwithstanding the verdict should be
    denied. . . .’ ” ’ [¶] When an appellate court reviews an order
    granting JNOV, it will ‘ “ ‘resolve any conflict in the evidence and

    , 606.)
    The testimony of a single witness may be substantial
    evidence, including the testimony of an expert. However, “when an
    expert bases his or her conclusion on factors that are ‘speculative,
    remote or conjectural,’ or on ‘assumptions . . . not supported by the
    record,’ the expert’s opinion ‘cannot rise to the dignity of substantial
    evidence’ . . . . [Citations.]” (Wise v. DLA Piper LLP (US) (2013)
    
    220 Cal. App. 4th 1180
    , 1191-1192; Jennings v. Palomar Pomerado
    Health Systems, Inc. (2003) 
    114 Cal. App. 4th 1108
    , 1117-1118.)
    B.      No Substantial Evidence Supported
    the Jury’s Verdict as to Johnson & Johnson
    Johnson & Johnson stopped producing Johnson’s Baby
    Powder in 1967. The trial court concluded there was no substantial
    evidence that Johnson & Johnson knew of any risk of harm from
    perineal use of talc prior to 1967, there was no evidence at trial
    sufficient to find the company directly liable after that time, and no
    substantial evidence to find Johnson & Johnson vicariously liable
    for any JJCI tort.
    On appeal, Echeverria argues the trial court misinterpreted
    the law and ignored evidence supporting the jury’s findings. We
    find no merit in these arguments.
    1.     Failure to warn
    A manufacturer has a duty to warn of facts which make a
    product dangerous or likely to be dangerous. “[A] product ‘likely’ to
    28
    be dangerous will ‘in all probability’ or ‘probably’ be dangerous.”
    (Valentine v. Baxter Healthcare Corp. (1999) 
    68 Cal. App. 4th 1467
    ,
    1483 (Valentine).) To establish a negligent failure to warn claim,
    the plaintiff must prove “ ‘that a manufacturer or distributor did
    not warn of a particular risk for reasons which fell below the
    acceptable standard of care, i.e., what a reasonably prudent
    manufacturer would have known and warned about.’ ” (Carlin v.
    Superior Court (1996) 
    13 Cal. 4th 1104
    , 1112 (Carlin).) “[A]
    reasonable manufacturer [is] not charged with knowing more than
    what would come to light from the prevailing scientific and medical
    knowledge.” (Valentine, at pp. 1483-1484.) “The manufacturer has
    no duty to warn of risks that are ‘merely speculative or conjectural,
    or so remote and insignificant as to be negligible.’ [Citation.]” (T.H.
    v. Novartis Pharmaceuticals Corp. (2017) 4 Cal.5th 145, 164
    (Novartis).)
    Under California law, a manufacturer generally has no duty
    to warn of risks from another manufacturer’s product, and is
    typically liable only for harm caused by its own product. (O’Neil v.
    Crane Co. (2012) 
    53 Cal. 4th 335
    , 349, 365; Taylor v. Elliott
    Turbomachinery Co., Inc. (2009) 
    171 Cal. App. 4th 564
    , 593-596.) It
    was undisputed that Johnson & Johnson ceased manufacturing
    Johnson’s Baby Powder after 1967. Echeverria was required either
    to establish that Johnson & Johnson breached a duty to warn
    between 1965 and 1967, or to advance and prove a theory under
    which the company could be liable even after it stopped
    manufacturing the product.
    2.    There was no substantial evidence
    Johnson & Johnson breached a duty to warn
    prior to 1967
    Echeverria contends Johnson & Johnson knew or should have
    known Johnson’s Baby Powder was unsafe by 1967 and it breached
    29
    its corresponding duty to warn consumers. There was no
    substantial evidence to support this theory. According to
    Echeverria’s evidence at trial, the first epidemiological study to
    investigate a link between perineal use of talc and ovarian cancer
    was published in 1982, 15 years after Johnson & Johnson ceased
    manufacturing the product. On appeal, Echeverria refers to a 1971
    study as evidence of Johnson & Johnson’s knowledge of the
    dangerousness of talc. Yet, plaintiff’s experts identified a 1982
    study as the “first” epidemiological study to address the issue. The
    1971 study was only obliquely mentioned when referenced in other
    documents. In any event, the 1971 study does not assist
    Echeverria’s argument since it was published four years after JJCI
    became responsible for Johnson’s Baby Powder. There was no
    evidence that Johnson & Johnson knew or should have known of
    the study or its results prior to the 1971 publication date.
    The only pre-1967 evidence Echeverria offered to support her
    claim was the 1964 internal memo, in which the scientist Ashton
    wrote that Dry Flo had replaced talc as a condom lubricant
    “ ‘because it was found to be absorbed safely in the vagina whereas,
    of course, talc was not.’ ” There was no evidence providing the
    context of this statement, no evidence that anyone had raised
    concerns regarding a link between talc and ovarian cancer by 1964,
    and no further explanation of the memo.10
    10    During the cross-examination of a defense expert, the jury
    was shown a 1996 article from the “Jersey Journal,” reporting that
    condom makers were no longer using talc due to “women’s health
    concerns.” The article stated: “ ‘Concern about talc as an ovarian
    carcinogen goes back 50 years in the medical literature.’ ” The trial
    court instructed the jury it was not to consider the statements in
    the article for their truth. The article was not admitted into
    evidence. The statements in the article cannot support Echeverria’s
    30
    Even if the jury could reasonably infer from the 1964 memo
    that Johnson & Johnson knew talc posed some danger to consumers
    because it was not safely absorbed into the vagina, this is a far cry
    from knowledge that perineal talc use created a risk of ovarian
    cancer. 
    (Carlin, supra
    , 13 Cal.4th at pp. 1112, 1116 [manufacturer
    must warn of particular risk]; see also Mitchell v. City of Warren
    (6th Cir. 2015) 
    803 F.3d 223
    , 230 [jury may not speculate that a
    manufacturer should have known about one risk because a
    separately known risk revealed the mere possibility of the first].)
    While inferences may support a judgment, “ ‘ “the inference must be
    a reasonable conclusion from the evidence and cannot be based
    upon suspicion, imagination, speculation, surmise, conjecture or
    guesswork. [Citation.]” ’ ” (Joaquin v. City of Los Angeles (2012)
    
    202 Cal. App. 4th 1207
    , 1219.) The jury could not reasonably infer
    from the 1964 memo that Johnson & Johnson was aware at that
    time of a risk of ovarian cancer from genital talc use.
    Echeverria argues the jury could infer from later documents
    that Johnson & Johnson knew or reasonably should have known in
    earlier years of the risks of genital talc use. But the next document
    admitted from defendants’ files, which referenced “the talc/ovary
    problem,” dated from 1975, eight years after Johnson & Johnson
    ceased manufacturing baby powder, and over a decade after Ashton
    wrote the 1964 memo. No document admitted at trial referred to
    the 1964 memo or cast any light on its interpretation. There was no
    legitimate basis for the jury to conclude from later documents,
    which reflected later developments in scientific knowledge about a
    link between talc and ovarian cancer, that Johnson & Johnson had
    similar knowledge in 1964. Indeed, Echeverria’s own expert,
    claims that the 1964 Ashton memo reflected an awareness that
    genital talc use created a risk of ovarian cancer.
    31
    Dr. Plunkett, testified that the fact that “talc is dangerous and
    capable of causing cancer” was likely to have been known since the
    early 1990’s; over two decades after Johnson & Johnson stopped
    producing Johnson’s Baby Powder.
    Echeverria further argues the trial court erred in requiring
    evidence that Johnson & Johnson “knew or should have known
    prior to 1967 that talc more probably than not caused ovarian
    cancer.” But, in our view, the most salient portion of the trial court
    ruling is the conclusion that “[t]here was no showing that as of 1967
    there was any suggestion by the scientific or medical community
    that talc was associated with ovarian cancer.” We agree with the
    trial court that there was no evidence indicating a link between
    ovarian cancer and talc was even suspected by 1967. Based on the
    evidence at trial about what was known or reasonably knowable by
    1967, a risk of ovarian cancer from perineal talc use would have
    been entirely speculative and conjectural, and Johnson & Johnson
    had no duty to warn of such risks.
    3.    There was no legal basis for the jury to find
    Johnson & Johnson liable for breaching a duty to
    warn after it ceased manufacturing the product
    Echeverria argues that even if Johnson & Johnson did not
    breach a duty to warn while it was manufacturing Johnson’s Baby
    Powder, a manufacturer has a continuing duty to warn after it
    stops making a product, and it remains liable even after a third
    party begins manufacturing the product. However, the authorities
    Echeverria cites for these propositions do not support her
    argument.
    For example, in Novartis, the court held a prescription drug
    maker that negligently fails to warn while it is producing a drug
    may be liable when the plaintiff is harmed by another
    manufacturer’s generic bioequivalent. Liability may continue even
    32
    after the original drug maker sells its rights in the brand-name
    drug to a successor. 
    (Novartis, supra
    , 4 Cal.5th at p. 156.) Yet, the
    Novartis court’s reasoning and analysis are inextricably tied to the
    “distinctive legal framework governing labeling for brand-name and
    generic pharmaceuticals.” (Ibid.) Federal regulations governing
    prescription drug labeling require the makers of generic
    bioequivalents, and successor manufacturers, to match the original
    brand-name manufacturer’s warning label as a default. (Id. at
    pp. 157-158, 182-183.) As a result, the original brand-name
    manufacturer’s failure to issue an adequate warning label may have
    foreseeable effects on consumers using another manufacturer’s
    generic bioequivalent, and on consumers who use the drug after a
    successor manufacturer takes over production and sales. (Id. at pp.
    174, 182-183, 192.)
    This case presents no such unique circumstances that would
    take it outside of the general rule that a manufacturer has no duty
    to warn of risks posed by another manufacturer’s product. (O’Neil
    v. Crane 
    Co., supra
    , 53 Cal.4th at pp. 364-366; Taylor v. Elliott
    Turbomachinery Co., 
    Inc., supra
    , 171 Cal.App.4th at pp. 593-596.)
    Further, as to successor prescription drug manufacturers, the
    Novartis court held “a brand-name manufacturer’s sale of the rights
    to a drug does not, as a matter of law, terminate its liability for
    injuries foreseeably and proximately caused by deficiencies present
    in the warning label prior to sale.” 
    (Novartis, supra
    , 4 Cal.5th at
    p. 191, italics added.) Novartis concerned continuing liability for a
    negligent failure to warn in labeling that occurred prior to a
    manufacturer divesting itself of the rights to the drug. (Id. at pp.
    183, 188, fn. 9 [court’s holding would not prevent the manufacturer
    in a given case from arguing it did not breach its duty given the
    scientific knowledge at the time].) This holding is of no assistance
    to Echeverria because there was no substantial evidence that
    33
    Johnson & Johnson negligently failed to warn prior to 1967, when it
    was manufacturing Johnson’s Baby Powder. Novartis does not
    support Echeverria’s argument.
    The other authorities Echeverria cites are equally inapt.
    Hernandez v. Badger Construction Equipment Co. (1994) 
    28 Cal. App. 4th 1791
    , and Balido v. Improved Machinery, Inc. (1972) 
    29 Cal. App. 3d 633
    , concerned the manufacturers’ alleged negligence in
    failing to correct a defect affecting an earlier model of a product still
    in use. Neither case addressed a duty to warn after the
    manufacturer has stopped making the product altogether, when the
    original product is no longer in use, or when the plaintiff alleges she
    was harmed by the product a different entity manufactured and
    sold.
    Echeverria did not argue that Johnson & Johnson had a
    separate duty to take corrective efforts as to the product it
    manufactured prior to 1967. (See, e.g., CACI No. 1223 [instructions
    for theory a defendant was negligent because it failed to
    recall/retrofit the product].) There was no evidence that Echeverria
    was using talcum powder Johnson & Johnson manufactured, i.e.,
    before 1967, years later. Indeed, such an inference would be
    unreasonable in light of the evidence regarding her frequency of
    use. 
    (Valentine, supra
    , 68 Cal.App.4th at p. 1482 [jury properly
    instructed that manufacturer’s duty to warn is a continuous duty
    which lasts as long as the product is in use; under the instructions
    given “as more information about adverse effects develops over
    time, the manufacturer must continue to provide physicians with
    warnings, at least so long as it is manufacturing and distributing
    the product”].) Echeverria did not present a legal theory to the jury
    that allowed it to find Johnson & Johnson liable for breaching a
    duty to warn that continued even after it stopped manufacturing
    the product, or after the product was no longer in use.
    34
    In her reply brief, Echeverria cites several cases from other
    jurisdictions espousing theories of products liability applicable to
    nonmanufacturers, such as “apparent manufacturer” liability, or
    the liability of a trademark licensor. Echeverria did not advance
    any such theory at trial. She tried the case on a negligent failure to
    warn theory only, not on a version of nonmanufacturer products
    liability represented in the cases she now cites on appeal. The
    jury’s verdict cannot be upheld based on legal or factual theories
    that were not advanced below. (Rayii v. Gatica (2013) 
    218 Cal. App. 4th 1402
    , 1409; Richmond v. Dart Industries, Inc. (1987)
    
    196 Cal. App. 3d 869
    , 874.) Nor was the jury required to make
    findings that would have been necessary for such a theory, even if it
    applied to Echeverria’s negligent failure to warn claim. (See Bay
    Summit Community Assn. v. Shell Oil Co. (1996) 
    51 Cal. App. 4th 762
    , 778 [factors necessary for strict liability of defendant outside of
    vertical distribution chain but involved in the production and
    marketing enterprise of a defective product]; Kasel v. Remington
    Arms Co. (1972) 
    24 Cal. App. 3d 711
    , 725-726; cf. Cleveland v.
    Johnson (2012) 
    209 Cal. App. 4th 1315
    , 1334 [verdict alternatively
    affirmed on ground for which the jury made necessary findings in
    association with another issue].)
    4.     There was no evidence to support a finding
    of liability arising out of Johnson & Johnson’s
    continued involvement in talc issues or based on it
    “directing” JJCI
    Echeverria contends the jury could reasonably find Johnson &
    Johnson had a continuing duty to warn because it played an active
    role in efforts to denigrate or conceal a link between talc and
    ovarian cancer. She asserts several documents from defendants’
    files that concerned talc referred to “Johnson & Johnson” only,
    suggesting the parent company’s involvement. She also points to
    35
    evidence that Johnson & Johnson was a member of the CTFA and it
    agreed to support a talc task force,11 and communications about
    talc included both Johnson & Johnson and JJCI employees.
    Echeverria argues this evidence showed the parent company was
    “directly involved” in failing to warn of the risks of Johnson’s Baby
    Powder.
    We disagree. The relevant question for purposes of the
    negligence claim is whether Johnson & Johnson, no longer the
    manufacturer of the injury-causing product, had a duty to
    Echeverria after 1967. (Ladd v. County of San Mateo (1996) 
    12 Cal. 4th 913
    , 917-918.) Evidence that Johnson & Johnson took
    actions to defend talc, to participate in industry trade groups, or to
    avoid a NTP or IARC characterization of talc as a carcinogen, does
    not in itself create a basis to hold Johnson & Johnson liable to
    Echeverria for negligence. Echeverria has failed to articulate a
    legal theory, supported by substantial evidence, that would have
    allowed the jury to find Johnson & Johnson had and breached a
    duty to Echeverria, even though JJCI was responsible for the
    product she used. Indeed, Echeverria’s failure to cite any legal
    authorities to support her theory—either below or on appeal—
    arguably waives this argument altogether. (Ewald v. Nationstar
    Mortgage, LLC (2017) 13 Cal.App.5th 947, 948.)
    Similarly, Echeverria contends the evidence showed Johnson
    & Johnson was “directing” JJCI’s actions, without citing legal
    authorities to specify her underlying legal theory. Nonetheless, the
    trial court considered Echeverria’s arguments to reflect an agency
    or alter ego theory of liability. The court concluded there was no
    substantial evidence to support either theory. We agree. JJCI is a
    11   There was evidence that a JJCI executive signed an
    agreement committing “Johnson & Johnson” to contribute funds for
    a CTFA task force.
    36
    wholly owned subsidiary of Johnson & Johnson, but evidence of a
    legal relationship between the two corporations is not, without
    more, sufficient for Johnson & Johnson to be held liable for JJCI’s
    actions. (Institute of Veterinary Pathology, Inc. v. California Health
    Laboratories, Inc. (1981) 
    116 Cal. App. 3d 111
    , 119.) Ambiguity
    arising out of similar company names is also not enough to
    establish liability. The record is devoid of any evidence of the
    relationship between Johnson & Johnson and JJCI, beyond the fact
    of the parent-subsidiary relationship and interaction of some
    employees. (Santa Clarita Organization for Planning &
    Environment v. Castaic Lake Water Agency (2016) 1 Cal.App.5th
    1084, 1106 [having some common personnel is not enough to show
    subsidiary is alter ego of parent].)
    The trial court properly rejected Echeverria’s claims that
    internal documents showed Johnson & Johnson directed or
    controlled JJCI. At most, the documents established Johnson &
    Johnson was involved in issues related to talc, sometimes in
    coordination with JJCI. The documents failed to create an
    inference that any such coordination was in fact control, or that
    Johnson & Johnson treated JJCI as merely a conduit or
    instrumentality of itself. (Santa Clarita Organization for Planning
    & Environment v. Castaic Lake Water 
    Agency, supra
    , 1 Cal.App.5th
    at pp. 1104-1106; Sonora Diamond Corp. v. Superior Court (2000)
    
    83 Cal. App. 4th 523
    , 541-542.)
    There was no substantial evidence to support a finding that
    Johnson & Johnson was liable to Echeverria for negligently failing
    to warn of the risks of perineal talc use. The trial court properly
    granted JNOV to Johnson & Johnson.
    37
    C.      Substantial Evidence Supported the Jury’s
    Finding That JJCI Breached Its Duty to Warn
    In its motion seeking JNOV, JJCI argued the evidence did not
    show that the prevailing scientific knowledge established talc to be
    dangerous by 2007, when Echeverria was diagnosed with ovarian
    cancer. The trial court rejected this theory as a ground for JNOV
    because defendants had not requested an equivalent jury
    instruction. On cross-appeal, defendants argue this was error and
    the trial court should have granted JNOV to JJCI on this
    alternative ground. Echeverria contends there was substantial
    evidence that JJCI breached a duty to warn.
    We need not decide if the trial court erred in concluding
    defendants’ failure to request a jury instruction on “prevailing
    scientific knowledge” prevented any consideration of the argument
    as a basis for JNOV. Even if this was error, substantial evidence
    supported the jury’s finding that JJCI breached a duty to warn of
    the risks of ovarian cancer from genital talc use, even with a 2007
    cutoff date.
    “Negligence law in a failure-to-warn case requires a plaintiff
    to prove that a manufacturer or distributor did not warn of a
    particular risk for reasons which fell below the acceptable standard
    of care, i.e., what a reasonably prudent manufacturer would have
    known and warned about.” (Anderson v. Owens-Corning Fiberglas
    Corp. (1991) 
    53 Cal. 3d 987
    , 1002.) As explained above, there is no
    duty to warn of risks that are merely speculative or conjectural. A
    manufacturer is “not charged with knowing more than what would
    come to light from the prevailing scientific and medical knowledge.”
    
    (Valentine, supra
    , 68 Cal.App.4th at pp. 1483-1484.) But the
    evidence as it applied to JJCI was sufficient to allow the jury to
    conclude the known risks of genital talc use were concrete enough
    38
    that it was unreasonable for JJCI to fail to warn consumers of
    them.
    The evidence established that between 1967 and 2007, there
    were several epidemiological studies finding a statistically
    significant association between genital talc use and ovarian cancer,
    as well as studies concluding talc can migrate to the ovaries.
    Internal documents reflected JJCI’s knowledge of the studies and of
    the evidence of increased risk of ovarian cancer associated with
    perineal talc use. The 1997 outside consultant letter reported to
    JJCI that by November 1994 “there had been about 9 studies (more
    by now) published in the open literature that did show a
    statistically significant association between hygienic talc use and
    ovarian cancer,” and that several independent reports provided a
    basis to conclude talc is capable of migrating to the ovaries. The
    evidence also established JJCI knew of the possibility the NTP or
    the IARC might designate talc as a carcinogen, and JJCI worked to
    avoid such a designation.
    JJCI argues the scientific evidence was inconclusive and did
    not establish a causal connection between talc and ovarian cancer.
    The jury could reasonably conclude the risks were significant and
    well-documented enough that JJCI had a duty to warn consumers.
    Studies had repeatedly shown an association between perineal talc
    use and ovarian cancer and there was evidence supporting a
    biological mechanism. A 1992 study recommended that women not
    use genital talc due to the risk of ovarian cancer. A 1999 study
    suggested women should be warned of the risks of ovarian cancer
    from genital talc use. In 2004, Luzenac was communicating its
    concern about the different pieces of evidence that together
    suggested a causal connection between perineal talc use and
    ovarian cancer. In 2006, Luzenac added a warning on its MSDS
    about the IARC 2B designation. That no regulatory or scientific
    39
    organization has conclusively identified talc as causing ovarian
    cancer is relevant, but not dispositive on the question of whether
    JJCI acted as a reasonably prudent manufacturer in deciding not to
    warn.
    Relying on Valentine, JJCI further argues there is no duty to
    warn unless it is probable, rather than possible, that the
    defendant’s product causes harm, and there was no evidence by
    2007 that talc was a probable cause of ovarian cancer.
    In Valentine, the court considered the difference between
    strict liability and negligent failure to warn claims to determine
    whether a jury’s conclusion that the defendant was not liable for
    strict liability failure to warn necessarily exonerated the defendant
    on a negligent failure to warn theory. 
    (Valentine, supra
    , 68
    Cal.App.4th at pp. 1480-1481, 1482.) The court concluded the
    instructions given in the case on strict liability failure to warn
    subsumed the elements of a negligent failure to warn claim.
    The Valentine court reasoned: “The manufacturer’s duty, per
    strict liability instructions, to warn of potential risks and side
    effects envelopes a broader set of risk factors than the duty, per
    negligence instructions, to warn of facts which make the product
    ‘likely to be dangerous’ for its intended use. A ‘potential’ risk is one
    ‘existing in possibility’ or ‘capable of development into actuality,’
    while a product ‘likely’ to be dangerous will ‘in all probability’ or
    ‘probably’ be dangerous. Stated differently, if [the defendant]
    adequately warned of potential risks and side effects, it of necessity
    warned of facts likely to render the product dangerous to the user.
    But, conversely, one could discharge the duty to warn of likely risks
    without discharging the duty to warn of potential risks. In sum, the
    manufacturer’s strict liability duty to warn is greater than its duty
    under negligence, and thus negligence requires a greater showing
    40
    by plaintiffs.” 
    (Valentine, supra
    , 68 Cal.App.4th at p. 1483, fns.
    omitted.)
    Here, there was substantial evidence that, if credited, allowed
    the jury to find that by 2007, a reasonable manufacturer would
    conclude there were facts showing genital talc use was likely to be
    dangerous, or “probably” dangerous. As noted above, there was
    evidence of repeated studies showing a statistical association
    between perineal talc use and ovarian cancer, evidence of migration
    of talc to the ovaries, and, according to the IARC designation, a
    credible but inconclusive causal interpretation of the observed
    association between talc use and increased risk of ovarian cancer.
    Moreover, as it concerned JJCI, this was not a case in which
    the evidence established the alleged danger was unknown or
    unknowable because of lack of scientific knowledge. Instead, the
    evidence presented a question of whether what was known was
    significant enough that JJCI acted unreasonably in failing to give
    an appropriate warning. What was known by 2007 went beyond,
    for example, “[k]nowledge of a potential side effect which is based
    on a single isolated report of a possible link between a prescription
    drug and an injury . . . .” (Finn v. G.D. Searle & Co. (1984) 
    35 Cal. 3d 691
    , 701.) While the evidence may not have been definitive
    or overwhelming, it was not so limited that we may determine the
    only reasonable conclusion was the risk of ovarian cancer from
    perineal talc use was unknown or unknowable in light of the
    prevailing scientific and medical knowledge.
    “The question whether there has been a breach of duty is
    usually a fact issue for the jury and may be resolved only as a
    matter of law if the circumstances do not permit a reasonable doubt
    as to whether the defendant’s conduct violates the degree of care
    exacted of [it]. [Citations.] If there is room for honest difference of
    opinion . . . as to whether there has been a breach of duty, the
    41
    question becomes one of fact for the jury.” (Putensen v. Clay
    Adams, Inc. (1970) 
    12 Cal. App. 3d 1062
    , 1077;

    Cork & Seal Co., Inc. (2010) 
    187 Cal. App. 4th 1220
    , 1239.) There
    was substantial evidence to support the jury’s finding that a
    reasonably prudent manufacturer would have known about the risk
    of ovarian cancer from genital talc use, and would have warned
    about that risk. (Carlin, at p. 1115; Anderson v. Owens-Corning
    Fiberglas 
    Corp., supra
    , 53 Cal.3d at p. 1002.)
    D.     Substantial Evidence Supported the Jury’s
    Finding on Specific Causation
    The trial court ruled Yessaian’s specific causation opinion was
    insufficient as a matter of law, identifying two main deficiencies in
    the testimony. First, the court reasoned Yessaian relied on
    epidemiological studies that did not support her opinion and she
    had no other basis for her conclusions. Second, the court found
    Yessaian purported to rule out other potential causes of
    Echeverria’s cancer but she either failed to completely eliminate
    alternative causes, or she did so based on speculation alone.
    Echeverria argues these conclusions misconstrued the record and
    were legal error. Keeping in mind the standard of review, we
    conclude the evidence was sufficient to support the jury’s causation
    finding.
    “ ‘ “Causation” is an essential element of a tort action.
    Defendants are not liable unless their conduct . . . was a “legal
    cause” of plaintiff’s injury. [Citations.].’ [Citation.] ‘Generally, the
    burden falls on the plaintiff to establish causation. [Citation.] . . .
    In the context of products liability actions, the plaintiff must prove
    that the defective products supplied by the defendant were a
    42
    substantial factor in bringing about his or her injury. [Citations.]’ ”
    (Whiteley v. Philip Morris, Inc. (2004) 
    117 Cal. App. 4th 635
    , 696.) A
    defendant’s negligence is not a substantial factor in bringing about
    harm if the plaintiff would have sustained the injury without the
    defendant’s negligence. (Viner v. Sweet (2003) 
    30 Cal. 4th 1232
    ,
    1240-1241.)
    “[I]n a personal injury action causation must be proven within
    a reasonable medical probability based upon competent expert
    testimony. Mere possibility alone is insufficient to establish a
    prima facie case. . . . There can be many possible ‘causes,’ indeed, an
    infinite number of circumstances which can produce an injury or
    disease. A possible cause only becomes ‘probable’ when, in the
    absence of other reasonable causal explanations, it becomes more
    likely than not that the injury was a result of its action.” (Jones v.
    Ortho Pharmaceutical Corp. (1985)

    , 402-403;

    1.    Yessaian’s Reliance on Epidemiological
    Studies Supported Her Opinion12
    The trial court relied in part on Daubert v. Merrell Dow
    Pharmaceuticals, Inc. (9th Cir. 1995) 
    43 F.3d 1311
    (Daubert II), in
    evaluating the sufficiency of Yessaian’s opinion. In Daubert II, the
    plaintiffs alleged the drug Bendectin caused their limb reduction
    birth defects. However, every published study had concluded the
    drug was not a teratogen. Epidemiological studies reported no
    statistical association between the drug and birth defects. (Id. at
    12     The trial court framed this issue as a lack of evidence to “rule
    in” talc as part of the differential diagnosis. We question what
    appears to be the combination of two distinct methods of proving
    specific causation—the use of epidemiological studies alone and the
    use of a differential etiology. The “ruling in” step of a differential
    diagnosis involves creating a list of causes that are generally
    capable of causing the disease. (Clausen v. M/V New 
    Carissa, supra
    , 339 F.3d at pp. 1057-1058.) In contrast, the 2.0 relative risk
    threshold is typically invoked with regard to specific causation—
    whether the agent caused an individual plaintiff’s disease. (In re
    Silicone Gel Breast Impl. Prod. Liab. 
    Lit., supra
    , 318 F.Supp.2d at
    p. 893 [relative risk of 2.0 not necessary to establish general
    causation]; King v. Burlington Northern Santa Fe Ry. (Neb. 2009)
    
    762 N.W.2d 24
    , 46-47 [declining to set 2.0 relative risk threshold for
    general causation].) In fact, the Reference Guide suggests
    “[d]ifferential etiologies are most critical when the agent at issue is
    relatively weak and is not responsible for a large proportion of the
    disease in question.” (Reference 
    Guide, supra
    , at p. 618.) The
    Reference Guide also notes ruling out known causes may allow a
    relative risk under 2.0 to support an inference that the agent more
    likely than not caused the plaintiff’s disease. (Id. at pp. 616-618.)
    However, we need not take up this issue. Whether as part of the
    differential diagnosis or as a separate means of proof, we conclude
    Yessaian’s reliance on epidemiological studies was a valid basis for
    her ultimate opinion.
    44
    p. 1314.) The court concluded the plaintiffs’ expert testimony on
    whether the drug was capable of causing limb reduction birth
    defects did not reflect findings that were derived by the scientific
    method and did not amount to “good science.” (Id. at pp. 1315-1316,
    1319-1320.)
    The court further held that even if the plaintiffs could show
    their experts’ findings were in fact derived by the scientific method,
    the plaintiffs still could not establish causation. Statistical
    probabilities derived from epidemiological studies were the only
    evidence the plaintiffs offered to show the drug caused their
    individual injuries. (Daubert 
    II, supra
    , 43 F.3d at p.1320.) The
    plaintiffs had to establish that their mothers’ use of the drug more
    than doubled the likelihood of birth defects because “only then can
    it be said that Bendectin is more likely than not the source of their
    injury.” (Ibid.) The Daubert II court thus held that “[f]or an
    epidemiological study to show causation under a preponderance
    standard, ‘the relative risk of limb reduction defects arising from
    the epidemiological data . . . will, at a minimum, have to exceed “2”.’
    [Citation.] That is, the study must show that children whose
    mothers took Bendectin are more than twice as likely to develop
    limb reduction birth defects as children whose mothers did not.”
    (Id. at p. 1321.)
    The court noted a “statistical study showing a relative risk of
    less than two could be combined with other evidence to show it is
    more likely than not that the accused cause is responsible for a
    particular plaintiff’s injury.” (Daubert 
    II, supra
    , 43 F.3d at p. 1321,
    fn. 16.) This was of no help to the Daubert II plaintiffs, however,
    since their experts did not seek to differentiate the plaintiffs from
    the subjects of the statistical studies they relied on. The court
    concluded “[t]he studies must therefore stand or fall on their own.”
    (Ibid.)
    45
    In Cooper v. Takeda Pharmaceuticals America, Inc. (2015)
    
    239 Cal. App. 4th 555
    (Cooper), a panel of this court adopted the
    Daubert II reasoning that only studies showing relative risk
    estimates greater than 2.0 are useful to the jury and may properly
    be used to “extrapolate from generic population-based studies to
    conclusions about what caused a specific person’s disease.” (Cooper,
    at p. 593.) However, the studies at issue in Cooper had relative risk
    estimates greater than 2.0. (Id. at pp. 562-564.) The court had no
    occasion to consider what role, if any, studies with lower relative
    risk estimates may play in an expert’s opinion.13
    a.   Yessaian relied on studies with risk ratios
    greater than 2.0
    Here, Yessaian relied on four studies which reported risk
    ratios greater than 2.0. The trial court rejected Yessaian’s reliance
    on the two studies that reported a 1.7 odds ratio for the serous
    histologic subtype. Still, the court acknowledged that left two
    studies with odds ratios greater than 2.0. These studies reported
    13    Numerous commentators have criticized the use of a 2.0
    relative risk threshold as a prerequisite to establishing specific
    causation. (See, e.g., Egilman et al., Proving Causation: The Use
    and Abuse of Medical and Scientific Evidence Inside the
    Courtroom—An Epidemiologist’s Critique of the Judicial
    Interpretation of the Daubert Ruling (2003) 58 Food & Drug L.J.
    223; Geistfeld, Scientific Uncertainty and Causation in Tort Law
    (2001) 54 Vand. L.Rev. 1011; Finley, Guarding the Gate to the
    Courthouse: How Trial Judges Are Using Their Evidentiary

    Relative Risk and Doubling Dose: A Methodologic Error That Has
    Become a Social Problem (1999) 89 Am.J. Public Health 1166.) The
    validity of a 2.0 threshold is not before us as Echeverria argues
    Yessaian in fact relied on epidemiological studies showing risk
    estimates greater than 2.0.
    46
    the risk of ovarian cancer among genital talc users to be over three
    and over four times greater than the risk in the unexposed. The
    trial court discounted Yessaian’s reliance on these studies because
    the results were not stratified by histologic subtype. However,
    there was no evidence offered at trial indicating study results were
    categorically irrelevant unless they showed stratified results for the
    serous subtype. Yessaian explained why she thought these
    particular risk estimates were appropriate when considering
    Echeverria’s case. The jury could accept her explanations.
    The lack of stratification for serous ovarian cancer in these
    two studies could certainly affect the weight of the evidence.
    Indeed, the trial court appeared to weigh the evidence when
    concluding that, “[i]n light of the other studies presented,” including
    the studies showing 1.7 odds ratios for serous ovarian cancer, and
    one study in which “no increased risk was shown,” the two studies
    with risk estimates greater than 2.0 were not substantial evidence
    supporting Yessaian’s opinion. But we may not weigh the evidence
    at this stage. We have no basis to conclude Yessaian’s reliance on
    the two “greater than 2.0” studies was invalid. Yessaian had
    epidemiological support for her opinion that talc was more likely
    than not responsible for causing Echeverria’s ovarian cancer, based
    on odds ratios greater than 2.0.
    b.    Yessaian’s reliance on studies with risk
    estimates less than 2.0 provided additional
    support for her opinion
    We also conclude Yessaian’s reliance on epidemiological
    studies with risk estimates less than 2.0 offered additional support
    for her opinion. Several courts have held, consistent with
    Daubert II, that while studies reporting relative risk estimates
    under 2.0 may not on their own establish specific causation, they
    may be combined with other evidence to provide proof of causation,
    47
    or to render an expert’s testimony sufficiently reliable to be
    admissible. (See, e.g., Ambrosini v. Labarraque (D.C. Cir. 1996) 
    101 F.3d 129
    , 135 [exclusion of expert testimony not warranted because
    it failed to “establish the causal link to a specified degree of
    probability”]; In re Joint Eastern & Southern Dist. Asbestos Lit. (2d
    Cir. 1995) 
    52 F.3d 1124
    , 1134 [declining to set standard mortality
    ratio “floor” as a matter of law]; Landrigan v. Celotex Corp. (N.J.
    1992) 
    605 A.2d 1079
    , 1087 [under some circumstances a study with
    relative risk less than 2.0 could support specific causation finding;
    2.0 relative risk is “not so much a password to a finding of causation
    as one piece of evidence, among others” for court to determine
    whether expert has used a sound methodology]; Carruth &
    Goldstein, Relative Risk Greater Than Two in Proof of Causation in
    Toxic Tort Litigation (Winter 2001) 41 Jurimetrics J. 195 [collecting
    cases between 1982 and 1999]; see also In re Hanford Nuclear
    Reservation Litigation (9th Cir. 2002) 
    292 F.3d 1124
    , 1136-1137
    [district court erred in requiring threshold level of radiation
    creating relative risk greater than 2.0 without regard to
    individualized factors].)
    Similarly, here, Yessaian did not rely on epidemiological
    studies with risk estimates under 2.0 alone to conclude talc was a
    substantial factor in causing Echeverria’s ovarian cancer. As
    explained above, she relied on studies with greater than 2.0 odds
    ratios. Yessaian also considered the dose-response relationship
    reflected in at least four studies, as well as Echeverria’s history of
    using talc for over 40 years, two or three times each day. Moreover,
    Yessaian did not only rely on epidemiological studies. She
    considered the migration studies and evidence regarding the
    general processes of inflammation and resulting carcinogenesis, in
    combination with the evidence of talc particles in Echeverria’s
    ovarian tissues and other areas where the cancer was found. Her
    48
    differential diagnosis evaluated and ruled out other known causes
    and risk factors. It was therefore permissible for Yessaian to also
    rely in part on epidemiological studies with risk ratios less than 2.0.
    2.     Yessaian’s Opinion Was Not Invalid for
    Failure to Rule Out Other Known Causes or the
    Possibility of an Unknown Cause
    The trial court concluded Yessaian did not properly employ
    the differential diagnosis methodology because her opinion ruling
    out age and the number of ovulatory cycles was speculative. The
    court also found Yessaian only “discounted” certain risk factors
    rather than eliminating them. The court additionally concluded
    Yessaian merely speculated when opining Echeverria’s cancer was
    not idiopathic. Echeverria asserts these conclusions ignored the
    evidence and misapplied the law. We conclude the entirety of the
    evidence established Yessaian’s methodology was not fatally flawed
    and her opinion was sufficiently supported.
    Cooper instructs our analysis. In Cooper, the plaintiff alleged
    the defendant’s drug caused his bladder cancer. 
    (Cooper, supra
    , 239
    Cal.App.4th at p. 561.) Following a jury verdict in the plaintiff’s
    favor, the trial court struck the specific causation expert’s testimony
    as speculative and lacking foundation, and granted JNOV. (Ibid.)
    The expert had conducted a differential diagnosis based on his
    review of the plaintiff’s medical records, review of the relevant
    literature, and his own scientific research. (Id. at pp. 566-567.) He
    ruled out numerous potential causes and risk factors, eventually
    concluding the defendant’s drug was the “ ‘most substantial
    causative factor.’ ” (Id. at pp. 567-570, 583.)
    The reviewing court held the trial court erred when it ruled
    the expert’s testimony was inadmissible because he failed to
    “adequately consider and definitively rule out” potential causes of
    the cancer other than the defendant’s drug. 
    (Cooper, supra
    , 239
    49
    Cal.App.4th at p. 577.) The court explained: “Under the applicable
    substantial factor test, it is not necessary for a plaintiff to establish
    the negligence of the defendant as the proximate cause of injury
    with absolute certainty so as to exclude every other possible cause of
    a plaintiff’s illness, even if the expert’s opinion was reached by a
    performance of a differential diagnosis.” (Id. at p. 578, original
    italics.)
    The defendant did not identify any relevant evidence about
    other causes it claimed the expert overlooked. The Cooper court
    reasoned the “critical point” was the defendant could not point to
    any substantial evidence to indicate that the expert ignored another
    cause of bladder cancer, other than the drug, such that his opinion
    was unreliable. 
    (Cooper, supra
    , 239 Cal.App.4th at p. 585.)
    The Cooper expert acknowledged there are many possible
    causes of bladder cancer and much still unknown about the etiology
    of the disease. This was not a proper basis for exclusion of the
    testimony in the absence of any substantial evidence to support the
    proposition that other possible causes in fact affected the plaintiff.
    
    (Cooper, supra
    , 239 Cal.App.4th at pp. 585-586.) The court
    reasoned: “California has rejected the notion that an expert must
    ‘exclude all “possibilities” ’ in reaching a specific causation opinion.
    [Citation.] Bare conceivability of another possible cause does not
    defeat a claim; the relevant question is whether there is ‘substantial
    evidence’ of an alternative explanation for the disease.” (Ibid.)
    In this case, the trial court concluded Yessaian did not
    sufficiently rule out age and number of ovulatory cycles. Our
    review of the record reveals that Yessaian considered these two risk
    factors and explained her decision to rule each factor out. As to age,
    Yessaian explained that while half of all women who get ovarian
    cancer do so between the ages of approximately 52 to 60 years old,
    Echeverria was on the younger side of that range. Were Echeverria
    50
    older at the time of diagnosis, Yessaian said she would have
    identified age—and the larger number of accompanying “genetic
    hits”—as a more likely cause of the cancer. But since Echeverria
    was at the younger end of the spectrum, Yessaian found age to be
    an unlikely cause.
    As to the number of ovulatory cycles, Yessaian explained that
    Echeverria’s age at menarche and menopause were both average.
    She described the risk related to ovulatory cycles as involving
    abnormally long periods of ovulation that occur when a woman has
    early menarche and late menopause. She did not believe
    Echeverria fit into this category, later noting Echeverria was
    menopausal at age 48, younger than the average age of menopause
    in American women. She also testified that she relied on several
    studies, included in her report, which informed her opinion that
    menarche at age 11 was not young enough to conclude early
    menarche was a cause of the cancer. She additionally opined that
    the number of ovulatory cycles is not an independent risk factor for
    postmenopausal ovarian cancer, referencing a particular study to
    support that opinion.
    Yessaian considered both age and number of ovulatory cycles
    and explained why she found them improbable as independent
    causes of Echeverria’s ovarian cancer. This was adequate.
    Yessaian was not required to conclusively exclude other potential
    causes for her testimony to be sufficiently reliable to support her
    opinion. 
    (Cooper, supra
    , 239 Cal.App.4th at pp. 585-586; see also
    Johnson v. Mead Johnson & Co., LLC (8th Cir. 2014) 
    754 F.3d 557
    ,
    563 [experts not required to rule out all possible causes when
    performing differential etiology; such considerations go to the
    weight of the evidence]; Messick v. Novartis Pharmaceuticals Corp.
    (9th Cir. 2014) 
    747 F.3d 1193
    , 1198 [expert must provide reasons
    for rejecting alternative hypotheses using scientific methods and
    51
    not based on speculation or subjective beliefs; expert may rely on
    clinical experience and need not identify sole cause for opinion to be
    reliable]; Westberry v. Gislaved Gummi AB (4th Cir. 1999) 
    178 F.3d 257
    , 265-266 [causation opinion not inadmissible for failure to rule
    out every possible alternative cause unless expert offers no
    explanation for why she has concluded an alternative cause was not
    the sole cause]; Heller v. Shaw Industries, Inc. (3d Cir. 1999) 
    167 F.3d 146
    , 156-157 [same].)
    Defendants argue for a restrictive reading of Yessaian’s
    testimony, taking isolated portions to conclude she “discounted”
    alternative causes rather than eliminating them. This approach
    conflicts with the standard of review we must apply. Yessaian used
    varying language to describe her process of rejecting other risk
    factors as the cause of Echeverria’s cancer. Taken as a whole,
    however, and drawing all inferences in favor of the verdict, the
    record supports the conclusion that Yessaian did “rule out”
    alternative causes, either concluding they were not independent
    risk factors, or explicitly testifying that in her opinion these other
    factors were not a cause. As in Cooper, defendants did not point to
    any substantial evidence to indicate Yessaian ignored age or
    number of ovulatory cycles, such that her opinion was unreliable or
    mere conjecture. (Cooper, 239 Cal.App.4th at p. 585; see King v.
    Burlington Northern Santa Fe 
    Ry., supra
    , 762 N.W.2d at pp. 50-51
    [expert did not fail to consider other possible hypotheses;
    defendant’s alternative suggestions for cause of disease affected
    weight of testimony only].) Defendants challenged Yessaian’s
    explanations on cross-examination and offered competing expert
    testimony. It was appropriate for the jury to determine the
    credibility of Yessaian’s testimony and to weigh it against
    contradictory evidence.
    52
    We also find the reasoning of Cooper instructive when
    considering “unknown causes.” There was no substantial evidence
    that unknown, yet-to-be-identified causes of ovarian cancer acted on
    Echeverria and provided an alternative explanation for her disease.
    As the court explained in Cooper, something more than bare
    conceivability or plausibility of other causes is required before
    another cause must be chosen as a matter of law as a cause in fact
    over the defendant’s conduct. 
    (Cooper, supra
    , 239 Cal.App.4th at
    p. 581.)
    As to the largely idiopathic nature of ovarian cancer, Yessaian
    testified the statement that “unknown etiology is the leading cause
    of cancer” is a general statement, applicable to the population as a
    whole. Her entire opinion was directed to answering the question of
    whether Echeverria’s cancer had a known cause or, in other words,
    that the cancer was not idiopathic. Yessaian’s testimony indicated
    she did not ignore idiopathy but instead determined there was in
    fact a known cause of the cancer, based on the factors she described.
    The credibility of her explanation was for the jury to determine.
    (See Wendell v. GlaxoSmithKline LLC (9th Cir. 2017) 
    858 F.3d 1227
    , 1237 [expert not required to eliminate all other possible
    causes of a condition for the testimony to be reliable; true in
    patients with multiple risk factors and in cases where there is a
    high rate of idiopathy]; In re Diet Drugs (E.D.Pa. 2012) 
    890 F. Supp. 2d 552
    , 562 [experts not required to exclude unknown or
    idiopathic causes for differential diagnosis to be reliable basis for
    their opinions].)
    The authorities defendants cite do not mandate a different
    result. In each case cited, the court first concluded the plaintiff
    failed to provide evidence of general causation. Stated otherwise,
    the plaintiffs’ experts failed to provide any admissible evidence that
    the defendants’ products were capable of causing the disease at
    53
    issue, in anyone. Without any evidence demonstrating the alleged
    toxin was even capable of causing disease, the experts could not
    reliably conclude the toxin caused the plaintiff’s disease, even if
    other known causes were ruled out. (Tamraz v. Lincoln Elec. Co.
    (6th Cir. 2010) 
    620 F.3d 665
    , 674-675 [expert had no nonspeculative
    basis to identify manganese exposure as a cause of the plaintiff’s
    parkinsonism]; Henricksen v. ConocoPhillips Co. (E.D.Wa. 2009)

    , 1162-1163, 1169-1170 [expert’s opinion that
    exposure to benzene in gasoline could cause AML was not supported

    440 F. Supp. 2d 465
    , 477 [expert testimony was inadmissible to establish general
    causation and differential diagnosis was therefore inappropriate].)
    Here, defendants have not argued there was no substantial
    evidence of general causation. We have also concluded Yessaian’s
    use of epidemiological and other scientific evidence to support her
    opinion identifying talc as the cause of Echeverria’s cancer was
    proper. (Compare Hall v. Conoco Inc. (10th Cir. 2018)

    diagnosis when cause of disease is unknown in majority of cases;
    54
    expert opinion that plaintiff’s disease had a known cause
    sufficiently reliable to be admitted].)
    In addition, while Yessaian was the sole specific causation
    expert, other evidence admitted at trial was relevant to the issue.
    Godleski, for example, opined there was evidence of a chronic
    inflammatory process in Echeverria’s tissues. In addition to
    providing a general causation opinion, Siemiatycki proffered an
    opinion that epidemiological evidence established a dose-response
    pattern, thus corroborating Yessaian’s opinion related to dose-
    response data.
    We consider whether there is any substantial evidence,
    contradicted or uncontradicted, to support the jury’s verdict.
    Yessaian’s opinion had multiple elements. One was the differential
    diagnosis ruling out other known causes. Another was
    epidemiological evidence in the form of studies showing risk ratio
    estimates greater than 2.0. Yet another was the evidence of dose
    response, evidence of Echeverria’s consistent and long years of
    heavy exposure, and the evidence of talc in her ovarian and other
    tissues. While a differential diagnosis alone may be insufficient as
    the sole basis for an opinion on the etiology of a largely idiopathic
    disease, that is not the situation before us. (See In re Diet 
    Drugs, supra
    , 890 F.Supp.2d at p. 563; Henricksen v. ConocoPhillips 
    Co., supra
    , 605 F.Supp.2d at pp. 1162-1163 [not impossible to prove
    specific causation in cases where most diagnoses are idiopathic but
    “in those cases, analysis beyond a differential diagnosis is
    required”].)
    Taken together, Yessaian’s specific causation opinion was
    supported by the epidemiological literature, including studies
    showing risk ratios greater than 2.0, her testimony regarding the
    biological mechanism in general and the presence of talc in
    Echeverria’s ovarian tissue and other areas where the cancer was
    55
    present, her clinical experience and treatment, her explanations
    addressing and ruling out other known risk factors and causes, and
    portions of the testimony of the other experts. (In re Joint Eastern
    & Southern Dist. Asbestos 
    Lit., supra
    , 52 F.3d at pp. 1132-1133
    [admissibility assessments concern individual pieces of evidence,
    but a sufficiency inquiry asks whether the collective weight of a
    litigant’s evidence is adequate to present a jury question; the issue
    is whether epidemiological and clinical data already in evidence
    was sufficient to justify the jury’s verdict finding causation].)
    The weaknesses in Yessaian’s testimony affected the weight
    of the evidence. They did not represent fundamental
    methodological flaws that rendered her testimony conjectural or
    insufficient as a matter of law. We may not reweigh the evidence,
    make credibility determinations, or disregard reasonable inferences
    that may be drawn in favor of the verdict. Substantial evidence
    supported the jury’s finding that talcum powder was a substantial
    factor in causing Echeverria’s cancer.
    E.    The Trial Court Properly Granted JNOV
    in Favor of JJCI as to Punitive Damages
    Echeverria contends the trial court erred in granting JNOV
    as to punitive damages. We find no error.
    Under Civil Code section 3294, a plaintiff may recover
    punitive damages by proving, by clear and convincing evidence, that
    the defendant acted with malice, fraud, or oppression. (Civ. Code,
    § 3294, subd. (a).) Malice “means conduct which is intended by the
    defendant to cause injury to the plaintiff or despicable conduct
    which is carried on by the defendant with a willful and conscious
    disregard of the rights or safety of others.” (Id., subd. (c)(1).)
    When there is no evidence the defendant intended to harm
    the plaintiff, there must be evidence of conduct that is both willful
    and despicable. (Lackner v. North (2006) 
    135 Cal. App. 4th 1188
    ,
    56
    1211, 1213.) Conscious disregard for the safety of another may be
    found “ ‘where the defendant is aware of the probable dangerous
    consequences of his or her conduct and he or she willfully fails to
    avoid such consequences.’ ” (Pfeifer v. John Crane, Inc. (2013) 
    220 Cal. App. 4th 1270
    , 1299. (John Crane).) “ ‘Despicable conduct’ is
    conduct that is ‘ “so vile, base, contemptible, miserable, wretched or
    loathsome that it would be looked down upon and despised by
    ordinary decent people.” ’ [Citation.] Such conduct has been
    described as having the character of outrage frequently associated
    with crime.” (Butte Fire Cases (2018) 24 Cal.App.5th 1150, 1159;
    College Hospital Inc. v. Superior Court (1994) 
    8 Cal. 4th 704
    , 725.)
    “[S]ince the jury’s findings were subject to a heightened
    burden of proof, we must review the record in support of these
    findings in light of that burden. In other words, we must inquire
    whether the record contains ‘substantial evidence to support a
    determination by clear and convincing evidence . . . .’ [Citation.]”
    (Shade Foods, Inc. v. Innovative Products Sales & Marketing, Inc.
    (2000) 
    78 Cal. App. 4th 847
    , 891 (Shade Foods).) JNOV was proper
    on the issue of punitive damages if no reasonable jury could find
    Echeverria’s evidence provided clear and convincing proof of malice.
    (Hoch v. Allied-Signal, Inc. (1994) 
    24 Cal. App. 4th 48
    , 60-61.)
    Viewed in the light most favorable to Echeverria, the evidence
    established JJCI was aware of studies showing an association
    between talc and ovarian cancer, studies showing talc could migrate
    from the vagina to the ovaries, and the theory and corresponding
    research suggesting talc caused inflammation, eventually leading to
    ovarian cancer. The evidence further established that, at least
    between the 1990’s and 2006, JJCI’s response to these studies was
    to mount a defense against them. In attempts to influence or
    persuade agencies such as the NTP and IARC, and in response to
    media or governmental inquiry, JJCI’s strategy was to describe the
    57
    flaws of these studies, point out inconclusive results, and highlight
    the absence of any established causal link. The jury could
    reasonably infer that, faced with the possibility that talc might be
    shown to cause ovarian cancer, JJCI’s response was focused solely
    on avoiding such a conclusion.
    However, it was also undisputed that there has not been
    direct, conclusive evidence establishing genital talc use causes
    ovarian cancer. While various entities have conducted evaluations
    of the entire body of relevant evidence, these have resulted in
    conclusions that fall short of a declaration that perineal use of talc
    is carcinogenic. The evidence demonstrated it is not universally
    accepted in the scientific or medical community that talc is even a
    significant risk factor for ovarian cancer. We note that despite the
    published cell, epidemiological, and animal studies, as well as the
    IARC 2B designation, Yessaian, a highly experienced gynecologic
    oncologist, had not warned her patients or their family members
    away from genital talc use until this litigation. She neither asked
    Echeverria about her talc use, nor advised her to stop using it.
    There was no evidence JJCI had any information about the
    dangers or risks of perineal talc use that was unavailable to the
    scientific or medical community. The company’s critiques of
    available evidence were largely consistent with third party entities’
    evaluations of the same studies, including nontrade groups such as
    the IARC and the FDA. (Cf. Boeken v. Philip Morris (2005) 
    127 Cal. App. 4th 1640
    , 1652-1655.)
    Echeverria’s epidemiological expert, Dr. Siemiatycki, testified
    that in 2006, when he chaired the IARC working committee on talc,
    he and the committee did not believe the available evidence was
    sufficient to conclude perineal use of talc caused ovarian cancer.
    Although there was evidence that JJCI attempted to “defend talc”
    and to avoid a carcinogenic designation by the IARC committee,
    58
    there was no evidence JJCI’s efforts had any impact on the
    committee’s ultimate conclusion that perineal talc use was possibly
    a carcinogen. Siemiatycki testified his changed opinion about
    perineal talc use was driven in large part by a study published in
    2013, six years after Echeverria was diagnosed with ovarian cancer,
    which he believed provided dose-response data that was previously
    absent.
    A defendant’s entire course of conduct may be considered for
    purposes of assessing punitive damage awards, including post-
    injury conduct. (Butte Fire 
    Cases, supra
    , 24 Cal.App.5th at p. 1176;
    Hilliard v. A.H. Robins Co. (1983) 
    148 Cal. App. 3d 374
    , 399-401.)
    We disagree, however, that JJCI’s actions or omissions in response
    to studies published after Echeverria incurred her injuries, which
    have offered new evidence or analysis, demonstrate a pattern or
    course of conduct that establishes the company’s ongoing conscious
    disregard of the safety of others that would apply equally to
    Echeverria. Scientific evidence developed post-injury did not create
    a reasonable inference that JJCI was acting with malice, pre-injury,
    in failing to warn of probable dangerous consequences of the
    product. Further, the post-injury conduct continued to fall short of
    establishing clear and convincing evidence of malice.
    Siemiatycki testified he believed the evidence of causation
    had grown stronger than it was in 2006. Yet, he also admitted the
    2013 study he relied upon for evidence of dose response included
    two analyses, one which showed a dose response and one which did
    not. There was further undisputed evidence that epidemiological
    studies published in 2016 and 2017 showed statistical associations
    no greater, and in some cases weaker, than those of earlier studies.
    Echeverria offered no evidence of any growing general scientific
    consensus that talc causes ovarian cancer. (Cf. John 
    Crane, supra
    ,
    220 Cal.App.4th at p. 1302 [malice shown where it was widely
    59
    accepted during relevant time period that product was carcinogenic;
    causal connection at significant exposure levels not disputed].)
    Defendants point out that the FDA has not concluded there is
    a causal link between talc and ovarian cancer. A defendant’s
    compliance with, or actions consistent with, governmental
    regulations or determinations about a product do not necessarily
    eviscerate a claim for punitive damages. (John 
    Crane, supra
    , 220
    Cal.App.4th at pp. 1301-1302.) But, here, the evidence showed the
    IARC has identified genital use of talc as possibly causing ovarian
    cancer and the statistical association between talc and ovarian
    cancer remains under scientific investigation. (See Satcher v.
    Honda Motor Co. (5th Cir. 1995) 
    52 F.3d 1311
    , 1316-1317 [no
    evidence to support punitive damages where there was a genuine
    dispute in scientific community about the benefit of the proposed
    safety measure, no independent organization required it, industry
    as a whole rejected the safety measure, and there were no definitive
    conclusions about effectiveness of the measure].) The evidence
    established that JJCI has refused to draw a causal connection
    between perineal talc use and ovarian cancer before experts in the
    relevant fields have done so. The jury could reasonably conclude
    this was unreasonable and negligent. But it is not clear and
    convincing evidence of “despicable conduct,” that is, conduct
    “ ‘ “[having] the character of outrage frequently associated with
    crime.” [Citation.]’ ” (American Airlines, Inc. v. Sheppard, Mullin,
    Richter & Hampton (2002) 
    96 Cal. App. 4th 1017
    , 1050.)
    In Shade Foods, the court noted “[a] record that presents a
    close case with regard to the sufficiency of the evidence of bad faith
    will inevitably provide a tenuous basis for supporting an award of
    punitive damages, since both the bad faith and punitive damage
    findings rest on inferences to be drawn from the same evidence.”
    (Shade 
    Foods, supra
    , 78 Cal.App.4th at p. 893.) Similar reasoning
    60
    applies here, since the failure to warn and punitive damages
    findings both rested on inferences to be drawn from the same
    evidence about the strength of the causal connection between talc
    and ovarian cancer, what JJCI knew about the risks of perineal talc
    use, when it obtained such knowledge, and what its legal
    responsibilities were with the information available. As in Shade
    Foods, while we have concluded there was sufficient evidence to
    support the jury’s finding that JJCI breached its duty to warn of the
    risks of perineal talc use, we do not take the further step of
    upholding the jury’s finding that JJCI acted with malice. (Ibid.)
    There was no substantial evidence to support a finding, by clear and
    convincing evidence, of despicable conduct which JJCI carried out
    with a willful and conscious disregard of the safety of others. (Civ.
    Code, § 3294, subd. (c).)
    II.    The Trial Court Did Not Abuse Its Discretion
    in Granting JJCI’s Motion for New Trial
    The trial court granted defendants’ motion for new trial on
    the grounds of insufficiency of the evidence (Code Civ. Proc.,
    § 657(6)), errors in law (id., § 657(7)), jury misconduct (id., § 657(2)),
    and excessive damages (id., § 657(5).) Echeverria contends the trial
    court erred as to each ground. We find no abuse of discretion in the
    trial court order granting the new trial motion on the ground of
    insufficiency of the evidence.
    A.    Standard of Review
    In her appellate briefing, Echeverria largely asserts the
    JNOV and new trial order must be reversed for the same reasons.
    Although we have concluded the JNOV in favor of JJCI as to
    liability must be reversed because there was substantial evidence to
    support the jury’s verdict, we apply a different standard of review
    when considering the trial court’s order granting a new trial. The
    California Supreme Court explained the differing standards in Lane
    61
    v. Hughes Aircraft Co. (2000) 
    22 Cal. 4th 405
    (Lane). In Lane, the
    trial court granted JNOV and, alternatively, a motion for new trial
    based on insufficiency of the evidence. The new trial order cross-
    referenced findings the trial court made in granting the JNOV. (Id.
    at p. 413.) The appellate court reversed the JNOV, finding
    substantial evidence supported the verdict. The court then
    determined it did not need to consider whether the evidentiary
    record supported the new trial order since it had analyzed whether
    sufficient evidence supported the verdicts with respect to the JNOV.
    (Id. at p. 411.) Our high court held the appellate court erred in
    applying the same standard when reviewing the JNOV and new
    trial order. (Id. at pp. 415-416.)
    As the Lane court explained, “an order granting a new trial
    under [Code of Civil Procedure] section 657 ‘must be sustained on
    appeal unless the opposing party demonstrates that no reasonable
    finder of fact could have found for the movant on [the trial court’s]
    theory.’ [Citation.] Moreover, ‘[a]n abuse of discretion cannot be
    found in cases in which the evidence is in conflict and a verdict for
    the moving party could have been reached . . . .’ [Citation.] In other
    words, ‘the presumption of correctness normally accorded on appeal
    to the jury’s verdict is replaced by a presumption in favor of the
    [new trial] order.’ [Citation.]” 
    (Lane, supra
    , 22 Cal.4th at p. 412.)
    Since the evidence in Lane could have supported a defense verdict,
    the appellate court erred in reversing the new trial order.
    This case presents similar procedural circumstances. Thus,
    although we have determined the JNOV in favor of JJCI as to
    liability must be reversed, we separately analyze the new trial
    order. “We defer to the trial court’s resolution of conflicts in the
    evidence if the decision is supported by substantial evidence and
    reverse only if there is no reasonable basis for the court’s decision or
    the decision is based on a legal error. [Citations.] [¶] An order
    62
    granting a new trial ‘will not be disturbed unless a manifest and
    unmistakable abuse of discretion clearly appears. . . . So long as a
    reasonable or even fairly debatable justification under the law is
    shown for the order granting the new trial, the order will not be set
    aside.’ [Citation.]” (Bell v. Bayerische Motoren Werke
    Aktiengesellschaft (2010) 
    181 Cal. App. 4th 1108
    , 1122.)
    B.     Discussion
    In granting the motion for new trial on the ground of
    insufficient evidence, the trial court concluded that, “[s]itting as the
    thirteenth juror, the Court is of the firm conclusion that the
    evidence of specific causation is not sufficient to support the verdict,
    for the reasons set forth above respecting the JNOV . . . and for the
    additional reason that Yessaian did not consider all available
    epidemiology and apply it to the facts relative to Echeverria except
    when it favored Echeverria.” The court found evidence of both
    specific and general causation was “lacking,” citing the “lack of
    anything other than a hypothesis about causation and the nature of
    the epidemiological evidence presented . . . .”
    We find no abuse of discretion. We reject Echeverria’s
    argument that the court made legal errors that require reversal of
    both the order granting JNOV in favor of JJCI and the order
    granting a new trial. In our view, the trial court’s ruling granting
    JNOV to JJCI as to liability must be reversed because the trial
    court weighed the evidence and made credibility determinations
    when rejecting and evaluating aspects of Yessaian’s testimony. In
    ruling on the new trial motion, however, the court was permitted to
    assess the credibility of witnesses, weigh the evidence, and draw
    inferences from the evidence different from those the jury may have
    drawn. (Licudine v. Cedars-Sinai Medical Center (2016)
    3 Cal.App.5th 881, 900; Fountain Valley Chateau Blanc
    63
    Homeowner’s Assn. v. Department of Veterans Affairs (1998) 
    67 Cal. App. 4th 743
    , 751.)
    The causation evidence was in significant conflict. For every
    plaintiff’s expert, there was a defense expert who offered opposing
    testimony, based on his or her own significant experience and
    review of the same or similar evidence and scientific literature.
    With respect to specific causation, the trial court found Yessaian
    “cherry picked” the studies without sufficient justification and the
    weight of the epidemiological evidence undermined her opinion.
    There was evidence to support this finding, namely, the testimony
    of defense experts Weed and Saenz, whose evaluation of the
    epidemiology conflicted with that of Yessaian. Although Yessaian
    did not rely on epidemiological studies alone, they remained an
    important basis of her opinion.
    The trial court also found there was no evidence of
    inflammation present in Echeverria’s tissue, rejecting Godleski’s
    testimony and inferences that could be drawn from it. While we
    have concluded a trier of fact could credit Godleski’s opinion that he
    observed a chronic inflammatory process in Echeverria’s tissues, a
    reasonable trier of fact could equally have determined defense
    expert Felix’s testimony was the more credible. Based on his
    examination of Echeverria’s tissue slides, Felix opined he saw no
    evidence of cancer-causing inflammation and, had it been present, it
    would have been easy to find.
    A reasonable jury could have given more weight to the
    defense interpretations of the epidemiology, rejected Yessaian’s
    interpretation of the literature as overly narrow or biased,
    questioned Godleski’s testimony and credited Felix’s testimony, and
    concluded the evidence did not sufficiently establish talc was a
    substantial factor in causing Echeverria’s cancer.
    64
    The evidence also supported the trial court’s reasoning on
    general causation. While Plunkett offered an opinion that talc
    causes ovarian cancer, a reasonable trier of fact would have been
    entitled to discredit or reject her testimony, in view of the
    limitations and critiques of several studies she relied upon. The
    weaknesses in the studies and her opinion were highlighted in her
    own testimony on cross-examination, and brought out in Andersen’s
    and Weed’s testimony. Weed also testified the available
    epidemiological and other scientific evidence did not support the
    conclusion that talc causes ovarian cancer. He, too, applied the Hill
    criteria and found the evidence did not support the factors
    sufficiently to state the “weak” statistical association between talc
    and ovarian cancer reflects a causal relationship.
    Despite the conclusive nature of Plunkett’s ultimate opinion,
    other evidence indicated no governmental or scientific agency has
    reached similar conclusions, and medical institutions have not
    uniformly taken steps to identify genital talc use as even a risk
    factor for ovarian cancer. Indeed, there was evidence that a 2017
    National Cancer Institute physician data query concluded the
    weight of the evidence did not support an association between
    perineal talc use and ovarian cancer.
    The evidence at trial would have supported a verdict in JJCI’s
    favor. The trial court did not abuse its discretion in granting the
    motion for new trial on the ground of insufficiency of the evidence.
    (McFarland v. Voorheis-Trindle Co. (1959) 
    52 Cal. 2d 698
    , 707.) We
    need not address the additional grounds on which the trial court
    granted the motion.
    65
