    Civil action commenced in the Superior Court Department on
    March 8, 2012.
    The case was tried before Diane M. Kottmyer, J.
    Jonathan D. Orent (Dennis A. Costigan with him) for the
    plaintiff.
    Robert T. Adams, of Missouri (Susan M. Donnelly Murphy with
    him) for the defendant.
    KATZMANN, J.     The plaintiff Diane Albright, an Ohio
    resident, brought this action in the Superior Court against

    Albright's amended complaint asserts claims against John
    Doe Corporations 1-50. The judgment entered in the Superior
    Court dismissed the action against the John Doe defendants as
    well as Boston Scientific Corporation.
    2
    defendant Boston Scientific Corporation (BSC), a Massachusetts-
    based company, seeking damages for injuries that she sustained
    after having BSC's "Pinnacle Pelvic Floor Repair" kit (Pinnacle
    device) surgically implanted to treat her pelvic organ prolapse
    (POP) condition.2   BSC designed, manufactured, and marketed the
    Pinnacle device and sold it to the Ohio hospital where
    Albright's surgery took place.    After a three-week trial, a jury
    found for BSC on Albright's claims of defective design and
    inadequate warning.
    On appeal, Albright challenges the exclusion of the medical
    application caution (caution) contained within the 2004 material
    safety data sheet (MSDS)3 that had been provided to BSC by its
    supplier of the polypropylene material used to fabricate the
    mesh in the Pinnacle device.     Albright offered the caution for
    the limited purpose of showing notice and knowledge on the part
    of BSC.   Albright also claims error from the exclusion of two
    letters that the United States Food and Drug Administration
    (FDA) sent to BSC in 2012.4    We conclude that, in the context of
    the case as it unfolded at trial, it was prejudicial error to

    prolapses) into the vagina. See Stedman's Medical Dictionary
    1573 (28th ed. 2006).
    3
    A 2007 MSDS that contained an identical caution was
    excluded as well.

    Albright also assigns as error the judge's refusal to give
    certain proposed jury instructions, discussed infra.

    exclude the proffered caution and FDA letters.     The judgment in
    favor of BSC shall therefore be vacated and the case remanded to
    the Superior Court for a new trial.
    Background.    There was evidence from which the jury could
    have found the following.5
    1.    Surgeries.   In 2008, Albright had surgery to treat POP
    symptoms involving her bladder.     Dr. Jay Meyer performed a
    procedure6 that did not involve the implantation of surgical
    mesh.     Less than twelve months later, Albright experienced a
    recurrence of the bulging sensation in her pelvic area.     During
    a follow-up visit with Dr. Meyer, Albright reported feeling
    "something give" in her pelvis after lifting a heavy table.       Dr.
    Meyer advised Albright that if she could tolerate this sensation
    of a bulge or pressure in her pelvic area, surgery could be
    avoided.    Albright was not able to do so; she met again with Dr.
    Meyer, voicing a desire to have "something done."
    Dr. Meyer informed Albright of an option to permanently
    implant a mesh device in her pelvic cavity to shore up weakened
    tissue.    Albright agreed.7   With the aid of an experienced
    5
    We reserve mention of certain evidence for our discussion
    of Albright's claims of error.

    A hysterectomy with anterior-posterior repair of the
    vaginal walls using native tissue.
    7
    Dr. Meyer, who had not previously used the Pinnacle
    device, suggested that the procedure be performed by a
    4
    colleague, Dr. Meyer performed the implant procedure at Mary
    Rutan Hospital, located in Bellefontaine, Ohio, on March 9,
    2010.     Mary Rutan Hospital had purchased the Pinnacle device
    from BSC on May 15, 2009.     At the time, Dr. Meyer was pleased
    with the surgical outcome, commenting favorably that the
    Pinnacle device worked "as advertised."
    BSC marketed the Pinnacle device as a safe implant for use
    in the treatment of POP.     The Pinnacle device is intended to
    shore up and repair tissue that holds and supports pelvic organs
    in place.     The FDA had cleared the device for sale in the United
    States pursuant to the agency's § 510(k) process.8
    2.    Postsurgery complications.   Within six months, Albright
    experienced pain and discomfort when urinating and other "hard-
    to-describe" pain in her pelvic area.     On examining Albright in
    September, 2011, Dr. Meyer found no indication of mesh erosion.
    specialist affiliated with the Ohio State University (at
    Columbus) medical center, Dr. Andrew Hundley. Albright asked
    Dr. Meyer to do the surgery, citing concerns about traveling to
    Columbus, which was some distance from her home.

    The FDA's review of a medical device for substantial
    equivalence is known as the § 510(k) process. Riegel v.
    Medtronic, Inc., 
    552 U.S. 312
    , 317 (2008). A new medical device
    need not undergo a rigorous premarket approval process if the
    FDA (as it did here) finds the new device is substantially
    equivalent to another device already on the market that is
    exempt from premarket approval. 
    Ibid. Devices that enter
    the
    market through the § 510(k) process have not been formally
    reviewed by the FDA for safety or efficacy.

    He suspected that Albright might have interstitial cystitis.9      No
    diagnosis was made linking Albright's symptoms and complications
    to the mesh.    Similar findings were made by Dr. Andrew Hundley
    during visits with Albright in 2011 and 2012, and by Dr. Maurice
    Chung, a gynecologist who examined Albright in 2012 and 2014.
    Albright was also examined by Dr. Niall Galloway, a
    urologist and gynecologist affiliated with Emory University, and
    Dr. John Steege, a professor in the department of gynecology and
    obstetrics at the University of North Carolina.   Drs. Galloway
    and Steege concluded that Albright was suffering from painful
    bladder syndrome and other complications due to the erosion and
    degradation of the mesh in her body.10
    3.   Trial proceedings.   Albright alleged that the Pinnacle
    device was defective due to a flawed design that failed to guard
    against the foreseeable risks of harm stemming from the mesh
    design.   She also claimed that BSC had failed to adequately warn
    Dr. Meyer of the foreseeable risks that the Pinnacle device
    posed to her.   BSC maintained that the Pinnacle device was safe
    for implantation inside Albright's body to treat POP.    The jury
    never reached the disputed factual question whether the Pinnacle
    9
    More than one expert testified that the terms
    "interstitial cystitis" and "painful bladder syndrome" are often
    "used interchangeably" in the medical community.
    10
    At trial, Drs. Galloway and Steege testified as experts
    on behalf of Albright.
    6
    device caused Albright's injuries because of their finding that
    Albright had not shown by a preponderance of the evidence that
    the device was "defective" under Ohio law.
    a.   Design.   Compared to other transvaginal surgical mesh
    devices on the market in 2009 for the treatment of POP, the
    Pinnacle device called for a sizable amount of dense mesh with
    small "pores" (i.e., openings in the mesh).   The design premise
    for the Pinnacle device is that when implanted in the body, its
    mesh will promote tissue growth through the mesh pores, and, by
    doing so, this new growth will anchor and stabilize the device
    in the patient's body.   BSC, however, did not conduct clinical
    tests to assess mesh shrinkage or degradation in the body.
    Experts for both sides addressed the scientific properties
    of BSC's polypropylene mesh.   Janice Connor, the clinical
    programs director of BSC's urology and women's health division,
    testified that her review of scientific literature confirmed
    that mesh devices, like the Pinnacle device, were a safe and
    effective medical option for women, especially when compared to
    native tissue repair surgeries which resulted in a recurrence
    rate of thirty to seventy percent.   Doreen Rao, an engineer in
    BSC's urology group, stated that polypropylene is "inert" and
    does not undergo changes once it is implanted in the human
    7
    body.11   On the other hand, Albright's experts focused on
    "oxidation," the response of tissue cells to the presence of a
    foreign body, in this case the implanted Pinnacle device.
    Scott Guelcher, a chemical engineering professor and
    polymer chemist, explained what happens when tissue cells react
    to polypropylene material.   Guelcher was among the first to
    discover that polypropylene materials, "which were normally
    considered stable," did, in fact, degrade.   Guelcher described
    this reactive process, testifying that human cells produce, or
    secrete, reactive oxygen species, which "settle on and attach
    to" the implant.   The response of human cells to implanted
    material is a "surface-driven" effect.   The cell-generated
    reactive oxygen species continuously break down and degrade the
    polypropylene mesh until it is destroyed or removed.   This means
    that the oxidation process results in a "bigger problem" where
    there is more polypropylene surface, as is the case with the
    Pinnacle device, which uses relatively more mesh than other POP
    mesh devices.   Guelcher added that polypropylene is one of the
    11
    Rao was also the "core team leader" for BSC's Polyform
    mesh kit, which contained the same mesh used in the Pinnacle
    device. On occasion, Rao had to address inquiries from
    physicians (and others) about mesh shrinkage. In one such
    instance, a project manager for the BSC urology group suggested
    that BSC "piggyback" on the shrinkage data of a mesh made from a
    different manufacturer (Gynemesh) "until we can prove
    otherwise." Again, BSC did not perform clinical tests to assess
    shrinkage of the mesh in the human body.
    8
    most easily oxidized materials, a fact that, in his view, is
    important to know for biomaterial design purposes.
    Dr. Thomas Barker, a professor of biomedical engineering at
    the university level, also testified for Albright.    Dr. Barker
    described a further nuance to the chemical reactive process.
    Dr. Barker testified that, upon implantation of the mesh device,
    human cells populate "dense portions" of the mesh (i.e., where
    its fibers are in close proximity to one another).   Tissue cells
    are activated to "apply force" and to pull on the mesh material.
    As a result, Dr. Barker testified, tissue then grows across mesh
    fibers ("fibrotic bridging"), rather than inside mesh pores, the
    latter of which is what the Pinnacle device is intended to
    promote.   This fibrotic bridging process may form a scar around
    the implant, which can cause pain to the patient.    Dr. Barker
    opined that there was a "mechanical mismatch" between the
    Pinnacle device and the anatomical space (the pelvic cavity)
    where the device is implanted.   As opposed to hernia mesh on the
    abdominal wall, the implanted Pinnacle mesh has two millimeters
    of soft tissue to protect it from extruding into the patient's
    vaginal cavity (a complication about which Albright complains).
    This mismatch can lead to foreseeable biomedical risks,
    including mesh contracture, mesh shrinkage, and abrasions.     Dr.
    Donald Ostergard, another of Albright's expert witnesses,
    testified at trial that the Pinnacle device was not appropriate
    9
    for its intended use to treat POP because of the volume, weight,
    and pore size of its mesh.    Albright's experts -- Guelcher,
    Barker, and Ostergard -- testified that, prior to marketing the
    Pinnacle device, BSC ignored or otherwise failed to account for
    the oxidation process as it affects the Pinnacle mesh when
    implanted to treat POP.
    b.   Warning and directions for use.    Albright presented
    expert evidence that BSC had failed to warn Dr. Meyer of the
    risk that the mesh's density and volume posed in terms of the
    frequency, permanence, and potential severity of complications
    caused by degradation of the mesh inside the body.    This
    included painful bladder syndrome and pudendal neuralgia, as
    well as the harm that would follow from a procedure to remove
    some or all of the mesh to address such complications.       BSC
    sought to show that the potential or anticipated risks
    associated with the Pinnacle device were fully disclosed in its
    directions for use (DFU).    The DFU for the Pinnacle device
    identified incontinence, dyspareunia, erosion, extrusion, and
    contracture, among other risks.   BSC's expert, Dr. Matthew
    Davies, testified that BSC had adequately warned Dr. Meyer of
    the risks in using its device.
    Discussion.   1.   Ohio products liability law.   Based on
    accepted conflict of laws principles, the judge ruled that
    Albright's substantive claims were controlled by Ohio law and
    10
    that evidentiary issues were governed by the law of
    Massachusetts, the forum State.   See Hodas v. Morin, 
    442 Mass. 544
    , 549-550 (2004); Feeney v. Dell, Inc., 
    454 Mass. 192
    , 206
    (2009); Fire Ins. Exch. v. Pring-Wilson, 
    778 F. Supp. 2d 116
    ,
    125 (D. Mass. 2011).12   We therefore provide a brief overview of
    Ohio products liability law.
    It is a deeply rooted principle in Ohio that a manufacturer
    is liable for foreseeable harm stemming from a product defect
    that could have been avoided or mitigated by exercising
    reasonable care.13   This principle is at the core of the Ohio
    Products Liability Act (OPLA), a comprehensive and detailed
    statutory plan that employs negligence concepts, such as
    foreseeable risk of harm and reasonable care.   See Ohio Rev.
    12
    See generally Restatement (Second) of Conflict of Laws
    § 145 (1971) ("The rights and liabilities of the parties with
    respect to an issue in tort are determined by the local law of
    the state which, with respect to that issue, has the most
    significant relationship to the occurrence and the parties
    . . .").
    13
    In 1908, the Ohio Supreme Court explained the common-law
    principle as follows: "[The] defendant in an action for
    negligence can be held to respond in damages only for the
    immediate and proximate result of the negligent act complained
    of, and in determining what is direct or proximate cause, the
    rule requires that the injury sustained shall be the natural and
    probable consequence of the negligence alleged; that is, such
    consequence as under the surrounding circumstances of the
    particular case might, and should have been foreseen or
    anticipated by the wrongdoer as likely to follow his negligent
    act." Miller v. Baltimore & Ohio S.W. R.R., 
    78 Ohio St. 309
    ,
    325 (1908), overruled on other grounds by Schultz v. Barbeton
    Glass Co., 
    4 Ohio St. 3d 131
    (1983). See Sutowski v. Eli Lilly
    & Co., 
    82 Ohio St. 3d 347
    , 351 (1998).
    11
    Code Ann. §§ 2307.71-2307.80 (West 2004 & Thomson Reuters Supp.
    2016).14   The term, "foreseeable risk," as used in the OPLA,
    defines the scope of a manufacturer's duty of care, which,
    simply put, is to guard against a known risk of harm or risks
    that the manufacturer "should recognize while exercising"
    reasonable care.   Ohio Rev. Code Ann. § 2307.71(A)(6)(b) (Supp.
    2016).15   See Ohio Rev. Code Ann. § 2307.75 (Supp. 2016) (design
    defect).   See also Ohio Rev. Code Ann. § 2307.76 (2004) (warning
    defect).
    While a manufacturer is not an insurer or guarantor of the
    safety of its products, it is nonetheless not free to ignore
    recognizable, or reasonably foreseeable, risks to consumers who
    use its products as intended.   Sutowski v. Eli Lilly & Co., 
    82 Ohio St. 3d 347
    , 352 (1998).    See Briney v. Sears, Roebuck &
    Co., 
    782 F.2d 585
    , 587 (6th Cir. 1986) (stating that product
    need not be "foolproof").   With this backdrop, we turn to the
    specific statutory claims in question.
    14
    As amended, the OPLA abrogates all common-law product
    liability causes of action that accrue after April 7, 2005. See
    Doty v. Fellhauer Elec., Inc., 
    175 Ohio App. 3d 681
    , 686 (2008).
    15
    Section 2307.71(A)(6)(b)(i)-(ii) specifies that a
    manufacturer should exercise both "[t]he attention, perception,
    memory, knowledge, and intelligence that a reasonable
    manufacturer should possess" and "[a]ny superior attention,
    perception, memory, knowledge, or intelligence that the
    manufacturer in question possesses."
    12
    a.   Design claim.   For the design claim, Albright had the
    burden to show, by a preponderance of the evidence, that when
    the Pinnacle device "left the control of [BSC], the foreseeable
    risks associated with its design . . . exceeded the benefits."
    Ohio Rev. Code Ann. § 2307.75(A).      See Welch Sand & Gravel, Inc.
    v. O & K Trojan, Inc., 
    107 Ohio App. 3d 218
    , 224 (1995).
    Foreseeability "usually depends on the defendant's knowledge."
    Menifee v. Ohio Welding Prod., Inc., 
    15 Ohio St. 3d 75
    , 77
    (1984).     The jury must principally focus on a given product's
    features so as to understand the product manufacturer's
    conscious design choices.     OPLA sets out a nonexhaustive list of
    factors that a jury may consider in determining whether a design
    defect exists.     A jury may look to factors such as:   (1) the
    "nature and magnitude" of the risks connected with the design in
    light of the product's "intended" use; (2) the "likely awareness
    of product users . . . of those risks"; and (3) the "likelihood"
    that the chosen design "would cause harm" in light of the
    product's intended use.      Ohio Rev. Code Ann. § 2307.75(B)(1)-
    (3).    The first and third factors are instructive here.
    The jury were required to closely scrutinize whether the
    mesh design for the Pinnacle device was suitable or appropriate
    for its intended use as a surgical implant to treat bladder POP.
    Suitability demands close attention to the actual area in the
    body where the Pinnacle mesh will remain implanted for many
    13
    years, not other areas of a patient's body (e.g., the abdomen)
    where surgical mesh has historically been used with positive
    results.    Albright was also required to present evidence of a
    practical and feasible alternative mesh design.      See Ohio Rev.
    Code Ann. § 2307.75(F).16
    b.   Warning claim.   For the warning claim, Albright bore
    the burden to show that BSC failed to adequately inform Dr.
    Meyer of foreseeable risks associated with the Pinnacle device.
    See Seley v. G.D. Searle & Co., 
    67 Ohio St. 2d 192
    , 202-203
    (1981) (discussing learned intermediary doctrine); In re Meridia
    Prod. Liab. Litigation, 
    328 F. Supp. 2d 791
    , 811-812 (N.D. Ohio
    2004) (listing factors relevant to whether warning for
    prescription drug is adequate).17     "Merely mentioning a possible
    injury or adverse effect is not necessarily adequate."      
    Id. at 812.
    Section 2307.76, which codifies a cause of action for
    inadequate warning, focuses the trier of fact on many of the
    16
    Albright did so, presenting evidence of a lightweight and
    smaller mesh containing larger pores, a design that was then
    available on the market.
    17
    The relevant factors include, but are not limited to, the
    following: whether the warning adequately indicates the scope
    of the danger; whether the warning reasonably communicates the
    extent or seriousness of the harm that could result from misuse
    of the product; whether the physical aspects of the warning
    adequately alert a reasonably prudent person to the danger; and
    whether the means to convey the warning are adequate in the
    given circumstances. In re Meridia Prod. Liab. Litigation,
    supra at 812.
    14
    same issues applicable to a product design claim.   A plaintiff
    must prove that the defendant manufacturer "knew or, in the
    exercise of reasonable care, should have known about a risk that
    is associated with the product and that allegedly caused harm
    for which the [plaintiff] seeks . . . compensatory damages," and
    that "[t]he manufacturer failed to provide the warning or
    instruction that a manufacturer exercising reasonable care would
    have provided concerning that risk, [both] in light of the
    likelihood that the product would cause harm of the type for
    which the [plaintiff] seeks . . . compensatory damages and in
    light of the likely seriousness of that harm."   Ohio Rev. Code
    Ann. § 2307.76(A)(1)(a)-(b).   The OPLA, for both design and
    warning claims, uses the negligence concepts of reasonable care
    and foreseeable risk of harm18 to guide a jury in determining
    liability.   "A warning is adequate if it reasonably discloses
    all inherent risks, and if the product is safe when used as
    directed."   Phan v. Presrite Corp., 
    100 Ohio App. 3d 195
    , 200
    (1994).   See Seley v. G.D. Searle & 
    Co., 67 Ohio St. 2d at 197
    -
    18
    For an illuminating discussion as to foreseeability
    generally, see Heng Or v. Edwards, 
    62 Mass. App. Ct. 475
    , 486
    (2004), where Justice Kaplan described the jury's role in a
    negligence case: "[T]he jury tries to reproduce the picture of
    what a reasonable person, as of the moment before the negligent
    act, would have foreseen as the likely harmful consequences of
    that act; alongside this picture the jury is to set the picture
    of the actual happening, and then to observe, in a general
    sense, how far the harm in fact experienced resembles any of the
    harms reasonably to have been foreseen" (footnote omitted).

    198; Crislip v. TCH Liquidating Co., 
    52 Ohio St. 3d 251
    , 255
    (1990).   This fact-based issue was sharply contested at trial.
    2.    Evidentiary errors.    a.   MSDS caution.   Albright claims
    prejudicial error from the exclusion of the caution on BSC's
    polypropylene supplier's MSDS.    The MSDS contained the following
    "MEDICAL APPLICATION CAUTION":
    "Do not use this [polypropylene] material in medical
    applications involving permanent implantation in the human
    body or permanent contact with internal body fluids or
    tissues."
    Albright offered the caution to show notice to BSC of a risk in
    using polypropylene for its implant device.     The judge excluded
    the caution on the grounds that Albright had not established its
    scientific basis and that the record was inconclusive as to the
    rationale of the supplier for including the caution on the MSDS.
    In Massachusetts, trial judges have wide discretion in
    ruling on the admissibility of evidence, and the judge's
    exercise of discretion is afforded much deference.      See, e.g.,
    Dahms v. Cognex Corp., 
    455 Mass. 190
    , 198 (2009).      A balancing
    principle, however, is that "relevant evidence should be
    admitted unless there is a quite satisfactory reason for
    excluding it."   DeJesus v. Yogel, 
    404 Mass. 44
    , 47 (1989),
    quoting from Crowe v. Ward, 
    363 Mass. 85
    , 88-89 (1973).
    We conclude that the MSDS caution was relevant, material
    evidence admissible for the limited purpose of showing that BSC,

    which had received the MSDS well before 2009, had notice or
    knowledge of the content of the caution.   See McNamara v.
    Honeyman, 
    406 Mass. 43
    , 55 (1989) (statement admissible to show
    that medical staff was alerted to possibility that patient was
    suicidal); Pardo v. General Hosp. Corp., 
    446 Mass. 1
    , 18 (2006)
    (memorandum admissible to show notice and knowledge).
    When considered solely for the purpose of demonstrating
    notice or the extent of BSC's knowledge, the caution was not
    hearsay.   See Mass. G. Evid. § 801(c) note (2016) (statement
    only hearsay if offered in evidence to prove truth of matter
    asserted as opposed to, inter alia, notice or effect of
    statement on hearer).   This is a long-standing rule in this
    Commonwealth.   See McNamara v. Honeyman, supra; Pardo v. General
    Hosp. 
    Corp., supra
    .
    Though the trial judge was understandably concerned about
    the scientific basis of the caution,19 here, where the caution

    diseases was not sufficient basis for expert opinion where

    manufacturer] used to generate its MSDS"); Johnson v. Arkema,

    17
    was not offered to establish causation or as the basis of an
    expert opinion but solely for the notice effect it had, or
    should have had on BSC, the absence of a scientific foundation
    for the MSDS caution is not a bar to admission.    See In re C.R.
    Bard, Inc., 
    810 F.3d 913
    , 923, 925-926 (4th Cir. 2016)
    (affirming Federal District Court's conclusion in suit for
    design defect and failure to warn that MSDS from polypropylene
    manufacturer was admissible as nonhearsay for limited purpose of
    showing that statement was made and that defendant was aware of
    it).    Cf. Sanchez v. Boston Scientific Corp., 
    38 F. Supp. 3d 727
    , 743 (S.D. W. Va. 2014), quoting from Cal. Civ. Code
    § 3294(c) ("A reasonable jury could find that by ignoring a
    warning on the MSDS and failing to conduct clinical testing,
    BSC's actions were 'despicable conduct' with willful and
    conscious disregard of the safety of consumers").
    As to the materiality of the caution, it is enough to say
    that the crux of this case has to do with BSC's "knowledge" (as
    of May 15, 2009) of the foreseeable risks connected with its
    Pinnacle device.    This evidentiary link is obvious when the
    caution is considered in the context of disputed factual issues
    under the OPLA.    The jury might have considered the caution's
    implications for BSC under both § 2307.75(A) to determine
    "foreseeable risks" (if any) tied to the Pinnacle design and
    § 2307.76(A)(1) to determine the warning that a prudent
    18
    manufacturer exercising reasonable care would have provided
    concerning a risk of harm to Pinnacle users.20   Any concerns
    about the jury's possible misuse of the caution for causation
    purposes or otherwise could have been addressed by an
    appropriate limiting instruction, and, if necessary, by a
    tailored statement in the jury charge.
    b.   FDA letters.   Albright also contends that it was
    prejudicial error to exclude two letters from the FDA to BSC.
    The first letter ordered BSC to conduct a "postmarket
    surveillance" study of the Pinnacle device to address concerns
    as to the safety and efficacy of the device in treating POP.
    The second letter agrees to a request from BSC to suspend its
    postmarket surveillance study because it planned to discontinue
    the manufacture and marketing of the Pinnacle device in this
    country.21   We conclude that, in the unique context of this
    lengthy trial, Albright ought to have been allowed to use the
    letters for the limited purpose of cross-examining BSC's
    witnesses, who had testified, without qualification, that the
    Pinnacle device was safe as of the time of trial.    Such a
    20
    Albright had the burden to prove that her surgeons would
    have acted differently if provided with adequate warnings. See
    Sanchez v. Boston Scientific 
    Corp., supra
    at 732.
    21
    As tried, there was no error in excluding a 2011 FDA
    public health notification, particularly since such
    postimplantation evidence was not relevant to Albright's alleged
    injuries or Dr. Meyer's decision to use the Pinnacle device for
    Albright's March 9, 2010, implant procedure.
    19
    limited use, to show bias or to rebut the witness's opinion
    testimony, would be reasonable cross-examination.   See generally
    Mass. G. Evid. § 611(b), (d).
    We add that the judge would have been well within her
    discretion to exclude all reference to the § 510(k) clearance
    (see note 
    8, supra
    ) because of its potential to mislead the jury
    and confuse the issues.   "That a device has been given clearance
    through the FDA's [§] 510(k) process is not relevant to state
    tort law. . . . The prejudicial value of evidence regarding the
    [§] 510(k) process far outweighs its probative value."   Sanchez
    v. Boston Scientific 
    Corp., 38 F. Supp. 3d at 744
    , quoting from
    Lewis v. Johnson & Johnson, 
    991 F. Supp. 2d 748
    , 754 (S.D. W.
    Va. 2014).   However, having permitted BSC to invoke the 510(k)
    clearance, it was error to preclude Albright from using the
    later-in-time (2012) letters in cross-examination of BSC experts
    or employees, who had addressed the FDA clearance, to rebut
    BSC's claim that its product was, in essence, "cleared" as a
    safe device.
    Having concluded that it was error to exclude the MSDS
    caution and prohibit Albright's use of the FDA letters for
    cross-examination purposes, we must determine whether any error
    was harmless or prejudicial.
    c.   Prejudice.   As a broad, general rule, error in the
    exclusion of evidence should not be grounds for a new trial
    20
    unless the error "has injuriously affected the substantial
    rights of the parties."   G. L. c. 231, § 119.   Construing this
    statutory text, the Supreme Judicial Court has held that "the
    substantial rights of a party are adversely affected when
    relevant evidence is erroneously excluded that, viewing the
    record in a commonsense way, could have made a material
    difference."   DeJesus v. 
    Yogel, 404 Mass. at 48
    .   This case, in
    our opinion, falls within that narrow band of appellate
    decisional law that has ordered a new trial for prejudicial
    evidentiary error.   See, e.g., Grant v. Lewis/Boyle, Inc., 
    408 Mass. 269
    , 274-275 (1990); Peterson v. Foley, 
    77 Mass. App. Ct. 348
    , 356-357 (2010).
    Here, exclusion of the MSDS caution substantially affected
    Albright's rights as, without this key piece of evidence, the
    jury did not have a complete picture of the information bearing
    on the safety of the Pinnacle device that BSC either knew of or,
    in the exercise of reasonable care, should have known about.       As
    noted above, the state of BSC's knowledge is a crucial aspect of
    the foreseeability analysis that underlies the claims in this
    case.   No other evidence before the jury served a similar
    function.
    The MSDS caution would have linked the scientific expert
    testimony and opinions of Guelcher and Barker regarding the
    reactive process of human tissue to surgically implanted mesh of
    21
    the volume and type used in the Pinnacle device to the primary
    concepts that were to guide the jury's determination of
    liability under the OPLA.   With respect to the design claim, the
    jury could have used the caution in conjunction with the expert
    oxidation evidence to assess BSC's evaluation of the risks and
    benefits connected with the design of the Pinnacle device.22     The
    caution is also material to the warning claim.   The
    ramifications of the caution in light of Albright's expert
    evidence would have been essential for the jury's ability to
    determine whether BSC exercised reasonable care in warning about
    the foreseeable risks associated with the Pinnacle device.
    In short, much of Albright's case depended on the limited
    admissibility of the MSDS caution to show notice on the part of
    BSC as to the unsuitability of polypropylene material for
    permanent implantation in the human body, particularly for use
    in the pelvic cavity.   The MSDS caution was not cumulative of
    other evidence in the case, including the unredacted portions of
    the MSDS document that were admitted in evidence.      BSC's
    challenge to the caution (that it was added at the insistence of
    legal counsel in response to liability concerns) goes to the
    22
    The jury could consider the cautionary warning as it
    pertained to the intended permanent implantation of the Pinnacle
    device in the human body where it would be in constant contact
    with internal body fluids and tissues and the extent to which
    BSC reasonably explored the likelihood that its chosen design
    would cause harm when used as intended.
    22
    weight of the caution, not its limited admissibility to show
    notice and knowledge.   See Sacco v. Roupenian, 
    409 Mass. 25
    , 28-
    30 (1990); Beal Bank, SSB v. Eurich, 
    444 Mass. 813
    , 815-816
    (2005).
    Further, the prejudice stemming from the exclusion of the
    caution was exacerbated by the inclusion of the FDA's clearance
    of the Pinnacle device in 2008, a point that BSC's counsel
    emphasized in closing argument.23    The judge also injected the
    issue of FDA approval into the trial, delivering a preliminary
    instruction informing the jury that the FDA had "cleared" the
    Pinnacle device for sale in this country in accordance with its
    § 510(k) process.   The repeated reference to the FDA's clearance
    aided BSC's defense, and handicapped Albright's case, on the
    central product safety issue in the case.    Against this trial
    backdrop, the MSDS caution and the FDA letters added necessary
    context to the § 510(k) clearance.    The exclusion of this
    evidence therefore left the jury with an incomplete picture of
    the events in question.   See note 1
    8, supra
    .
    23
    Outside the presence of the jury, the judge admonished
    BSC's counsel for "exceed[ing] the permissible scope of argument
    on the FDA by referring to the fact that the [Pinnacle device]
    was cleared and all of these other [surgical mesh-related]
    products were cleared." The judge determined that it was
    necessary to instruct the jury that they "may not consider the
    fact that the Pinnacle was cleared by the FDA as evidence that
    the Pinnacle was a safe or effective medical device."
    23
    3.   Other claims of error.   Based on our disposition here,
    there is no need to resolve Albright's claims respecting the
    judge's refusal to instruct the jury on the "heeding
    presumption" and a manufacturer's postsale duty to warn.      We
    address them only briefly to provide guidance in the event that
    these issues arise again at any retrial.
    a.   Postsale duty to warn.   There was little (if any)
    evidence at trial to suggest that BSC became aware of a new risk
    associated with the Pinnacle device subsequent to the March,
    2010, implant procedure.   While a manufacturer has a postsale
    duty to warn under Ohio Rev. Code Ann. § 2307.76(A)(2), the
    trial record did not warrant a further instruction on a postsale
    duty, particularly where the trial judge had delivered a proper
    instruction concerning BSC's duty to warn under Ohio law and the
    factors that the jury should consider in determining whether the
    warning and directions for use were adequate.
    b.   Heeding presumption.   Albright contests the judge's
    refusal to instruct the jury that they could presume that an
    adequate product warning by BSC would have been followed by the
    surgeon who performed the implant procedure.     Should this issue
    arise at a retrial, we would expect the parties to provide
    guidance to the trial judge as to the propriety of such an
    instruction based on well-settled Ohio law.     See Seley v. G.D.
    24
    Searle & 
    Co., 67 Ohio St. 2d at 200
    ; Miller v. ALZA Corp., 
    759 F. Supp. 2d 929
    , 936 (S.D. Ohio2010).
    Conclusion.   The judgment is vacated and the case remanded
    to the Superior Court for proceedings consistent with this
    opinion.
    So ordered.
