    NEW MEDICAL HORIZONS, II, LTD. D/B/A CYPRESS FAIRBANKS
    MEDICAL CENTER, ANAND BALASUBRAMANIAN, M.D., AND DOAN
    K. NGUYEN, M.D., Appellants
    V.
    VICKIE MILNER, Appellee
    On Appeal from the 61st District Court
    Harris County, Texas
    Trial Court Case No. 2016-79980
    OPINION
    Appellee Vickie Milner, a diabetic, was admitted to Cypress Fairbanks
    Medical Center for a left-foot infection. She alleges that the negligence of appellants
    Anand Balasubramanian, M.D., Doan K. Nguyen, M.D., and the nursing staff of
    New Medical Horizons, II, LTD D/B/A Cypress Fairbanks Medical Center led to a
    gangrenous condition, resulting in amputation of her great toe followed by a
    protracted recovery.
    The appellants moved to dismiss Milner’s healthcare liability claims, claiming
    that her expert’s report was inadequate. In this interlocutory appeal, Dr.
    Balasubramanian, Dr. Nguyen, and the Medical Center contend that the trial court
    abused its discretion in denying their motions to dismiss. In his three issues, Dr.
    Balasubramanian argues that the trial court abused its discretion by denying his
    motion to dismiss because: (1) the report of Milner’s expert, Marc E. Mitchell, M.D.,
    failed to establish his qualifications to provide an expert report as to Dr.
    Balasubramanian; (2) Dr. Mitchell’s report failed to provide a sufficient opinion on
    the applicable standard of care and breach as to Dr. Balasubramanian; and (3) Dr.
    Mitchell’s report failed to link Milner’s damages to any specific breach by Dr.
    Balasubramanian.
    In his sole issue, Dr. Nguyen argues that the trial court abused its discretion
    by denying his motion to dismiss because Dr. Mitchell’s causation opinions are
    conclusory. In its sole issue, the Medical Center argues that the trial court abused its
    discretion by finding Dr. Mitchell’s expert report sufficient and denying its motion
    to dismiss because Dr. Mitchell’s report failed to provide the necessary fair summary
    2
    of the standard of care applicable to the Medical Center’s nursing staff, a breach of
    any applicable standard of care, and causation of any injuries by such a breach.
    We affirm the trial court’s orders.
    Background
    The medical records are not before us, and we accept the factual statements in
    Dr. Mitchell’s expert report for the limited purpose of this appeal. See Marino v.
    Wilkins, 
    393 S.W.3d 318
    , 320 n.1 (Tex. App.—Houston [1st Dist.] 2012, pet.
    denied).
    On March 22, 2015, Milner presented to the Medical Center’s Emergency
    Department with an infected left foot. Her diabetic status was known by the
    healthcare providers. Her foot was noted to be swollen and “blood red with some
    black.” She was admitted to the Medical Center that same day under the care of Dr.
    Balasubramanian, an internal medicine physician who was Milner’s attending
    physician during her hospitalization. Significant findings included hyperglycemia,
    an elevated white blood count, and x-ray evidence of a metallic foreign body in her
    left foot. Milner was treated with intravenous antibiotics. Dr. Balasubramanian
    ordered an infectious disease consultation (which was performed on March 23,
    2015), and he also noted that the pulse in Milner’s left foot was difficult to palpate.
    On March 24, 2015, Dr. Balasubramanian ordered a surgical consultation with Dr.
    3
    Nguyen, who recommended removal of the foreign body and incision and
    debridement of the left distal foot.
    On March 25, 2015, Milner underwent incision and drainage of the foot by
    Dr. Nguyen. Noted findings by Dr. Nguyen included that Milner was at high risk for
    the possibility of eventually losing her toes because of her diabetes and poor
    circulation. The dorsal tissue on the plantar aspect of the great toe was found to be
    blackish. After the surgery, Dr. Nguyen noted that Milner tolerated the procedure
    well and that his plan was for her to undergo wound care and observation.
    In the days following the March 25 surgery, there appears to have been little
    or no physician follow-up or observation of the condition of Milner’s foot wound.
    Dr. Mitchell stated that he saw no evidence in the medical record that Dr.
    Balasubramanian ever examined the wound until March 30, after Milner was
    scheduled to be discharged home. There was also little or no documented wound
    care to indicate whether the wound treatment plan was working. Milner was
    scheduled to be discharged home on March 30, but when her daughter arrived to
    pick her up from the Medical Center, it was discovered that Milner had a gangrenous
    diabetic left-foot infection. Dr. Balasubramanian requested a vascular consult that
    day.
    A March 31, 2015 CT scan showed occlusion of the distal superficial femoral
    artery, and Milner was moved to the ICU. On April 10, 2015, she underwent
    4
    amputation of her great toe. On April 5, 2016, Milner had “left above-the-knee
    femoral popliteal bypass surgery.” Her preoperative diagnosis was critical limb
    ischemia and prior amputation of her great toe. She has continued to require
    debridement procedures on her left foot.
    Milner filed suit, and within the 120-day deadline of section 74.351(a) of the
    Civil Practice and Remedies Code, she provided the defendants with Dr. Mitchell’s
    original expert report and then an amended report. The defendants objected that
    these reports failed to satisfy section 74.351(r)(6); the trial court agreed but granted
    Milner a thirty-day extension to serve a sufficient report under section 74.351(c).
    Milner then provided Dr. Mitchell’s second amended report, which supersedes his
    initial and first amended reports. See Cornejo v. Hilgers, 
    446 S.W.3d 113
    , 124 n.11
    (Tex. App.—Houston [1st Dist.] 2014, pet. denied). The defendants objected to Dr.
    Mitchell’s second supplemental report (referred to in this opinion as Dr. Mitchell’s
    report) and moved to dismiss Milner’s claims for her alleged failure to serve a
    sufficient expert report under section 74.351. The trial court overruled the objections
    and denied the motions to dismiss, and this interlocutory appeal followed.
    Chapter 74 Expert Reports
    Section 74.351 of the Texas Medical Liability Act (TMLA) provides that no
    medical negligence cause of action may proceed until the plaintiff has made a good-
    faith effort to demonstrate that a qualified medical expert believes that a defendant’s
    5
    conduct breached the applicable standard of care and caused the claimed injury. See
    TEX. CIV. PRAC. & REM. CODE § 74.351(l), (r)(6). “[T]he purpose of the expert report
    requirement is to weed out frivolous malpractice claims in the early stages of
    litigation, not to dispose of potentially meritorious claims.” Abshire v. Christus
    Health Se. Tex., 
    563 S.W.3d 219
    , 223 (Tex. 2018) (per curiam).
    To constitute a good-faith effort, the report must provide enough information
    to fulfill two purposes: (1) inform the defendant of the specific conduct that the
    plaintiff has called into question; and (2) provide a basis for the trial court to
    conclude that the claim has merit. Baty v. Futrell, 
    543 S.W.3d 689
    , 693–94 (Tex.
    2018); Am. Transitional Care Ctrs. of Tex., Inc. v. Palacios, 
    46 S.W.3d 873
    , 878–
    79 (Tex. 2001). A report that merely states the expert’s conclusions about standard
    of care, breach, and causation does not fulfill these two purposes. 
    Palacios, 46 S.W.3d at 879
    . The expert must explain the basis for his statements and link his
    conclusions to the facts. Bowie Mem’l Hosp. v. Wright, 
    79 S.W.3d 48
    , 52 (Tex.
    2002). It has been recognized that the supreme court “has construed the TMLA as
    setting a relatively low bar as to what comprises an adequate expert report.” 
    Baty, 543 S.W.3d at 698
    (Johnson, J., dissenting).
    In determining whether the report meets these requirements, the court should
    look no further than the report itself because all of the information relevant to the
    inquiry must be contained within the report’s four corners. Bowie Mem’l Hosp., 
    79 6 S.W.3d at 52
    . The expert report is not required to marshal all of the plaintiff’s proof
    necessary to establish causation at trial. 
    Id. An expert
    report does not have to meet
    the same requirements as the evidence offered in a summary-judgment proceeding
    or at trial. Miller v. JSC Lake Highlands Operations, LP, 
    536 S.W.3d 510
    , 517 (Tex.
    2017) (per curiam). The “only question” is whether the report provides “enough
    information” for the trial court to conclude that it constitutes a good-faith effort. Id.;
    see also 
    Baty, 543 S.W.3d at 696
    –97. We are also mindful that expert-report
    challenges are made at an early, pre-discovery stage in the litigation. See 
    Baty, 543 S.W.3d at 697
    & n.10 (rejecting argument that expert report was inadequate,
    concluding that expert report sufficed “particularly in light of the purposes the report
    is intended to serve” at an early stage in litigation, and stating “additional detail is
    simply not required at this stage of the proceeding”).
    Standard of Review
    We review a trial court’s ruling on a motion to dismiss for an abuse of
    discretion. 
    Abshire, 563 S.W.3d at 223
    ; 
    Palacios, 46 S.W.3d at 875
    . “A trial court
    abuses its discretion when it acts in an arbitrary or unreasonable manner or without
    reference to any guiding rules or principles.” Bowie Mem’l 
    Hosp., 79 S.W.3d at 52
    .
    As a court reviewing matters committed to the trial court’s discretion, we may not
    substitute our own judgment for that of the trial court merely because we would have
    ruled differently. See 
    id. When reviewing
    decisions that fall within the trial court’s
    7
    discretion, “[c]lose calls must go to the trial court.” Larson v. Downing, 
    197 S.W.3d 303
    , 304 (Tex. 2006) (per curiam).
    Analysis
    Qualifications
    In his first issue, Dr. Balasubramanian, an internal medicine physician,
    contends that the expert report of Dr. Mitchell, a vascular surgeon, failed to establish
    Dr. Mitchell’s qualifications to provide an expert report as to Dr. Balasubramanian.
    Dr. Mitchell, a medical doctor who obtained his medical degree from
    Georgetown University School of Medicine, is a fellowship-trained and board-
    certified vascular surgeon and general surgeon. He has over twenty years of
    experience in an academic medical center, where he is actively involved in the
    training of medical students, has a busy clinical practice, and routinely cares for
    patients with conditions similar to Milner’s. His report states:
    Specifically, I have treated, performed surgery, and managed the care
    of many patients with diabetic foot wounds. I am very familiar with the
    accepted standards of medical care for the treatment of a foreign body
    in the foot of a diabetic patient. Caring for such wounds involves a team
    approach. I work closely with wound care nursing staff and rely on
    wound care nursing staff to document the condition of a wound and
    advise me when a wound is deteriorating. In light of my training,
    knowledge, experience and qualifications as set forth above, I am
    familiar with the standard of care for an admitting hospital, wound care
    nurse, attending physician and surgeon with respect to the care and
    treatment of Vickie Milner in March, 2015. I am familiar with the
    responsibilities and duties these parties provide to a patient with the
    signs, symptoms and history Vickie Milner presented with in March,
    2015.
    8
    Regarding the standards of care applicable to Dr. Balasubramanian and to Dr.
    Nguyen, an orthopedic surgeon, Dr. Mitchell’s report states:
    These standards of care apply to any physician treating an infected foot
    in the presence of a foreign body in a diabetic patient, regardless of the
    physician’s specialty. Any attempt to create a superficial difference in
    the standards of care between what would have been expected of an
    internist and what would have been expected of an orthopedic surgeon,
    when faced with the facts and circumstances of this case, is a red
    herring. The standards of care and failures to meet the appropriate
    standards of care set out in my report, are standards basic to the general
    practice of medicine that any general practitioner or resident treating
    diabetic patients with foot infections should know. There is nothing
    novel about the applicable standards of care for treating a patient with
    conditions similar to those of Vickie Milner in March, 2015.
    Dr. Balasubramanian specifically argues that Dr. Mitchell provides no
    explanation for how he is qualified to render an opinion on the standard of care for
    an attending physician who is board certified in internal medicine. Regarding Dr.
    Mitchell’s assertions that he is familiar with treating treating injuries like Milner’s
    and that he is familiar with the standard of care applicable to all healthcare providers
    who would treat those injuries, Dr. Balasubramanian argues that Dr. Mitchell’s
    assertions are not supported and are conclusory.
    In a healthcare liability suit, whether an expert witness is qualified to offer an
    expert opinion under the relevant statutes and rules lies within the sound discretion
    of the trial court. Puppala v. Perry, 
    564 S.W.3d 190
    , 202 (Tex. App.—Houston [1st
    Dist.] 2018, no pet.). The expert’s qualifications must appear in the four corners of
    9
    the expert report or in the expert’s accompanying curriculum vitae. 
    Id. “An expert
    report by a person not qualified to testify does not represent a good-faith effort to
    comply with the definition of an expert report.” Mettauer v. Noble, 
    326 S.W.3d 685
    ,
    693 (Tex. App.—Houston [1st Dist.] 2010, no pet.).
    To qualify as an expert for the purpose of an expert report against a physician,
    a person must be a physician who:
    (1)    is practicing medicine at the time such testimony is given or was
    practicing medicine at the time the claim arose;
    (2)    has knowledge of accepted standards of medical care for the
    diagnosis, care, or treatment of the illness, injury, or condition
    involved in the claim; and
    (3)    is qualified on the basis of training or experience to offer an
    expert opinion regarding those accepted standards of medical
    care.
    TEX. CIV. PRAC. & REM. CODE § 74.401(a); see 
    id. § 74.351(r)(5)(A)
    (defining
    “expert” qualified to give opinion on “whether a physician departed from accepted
    standards of medical care” as “an expert qualified to testify under the requirements
    of Section 74.401”). Section 74.401(c) further provides that in determining whether
    an expert witness is qualified based on his training and experience, a trial court shall
    consider whether the witness is “board certified or has other substantial training or
    experience in an area of medical practice relevant to the claim,” and whether he “is
    actively practicing medicine in rendering medical care services relevant to the
    claim.” 
    Id. § 74.401(c).
    10
    The expert must do more than show that he is a physician, but he “need not
    be a specialist in the particular area of the profession for which testimony is offered.”
    Owens v. Handyside, 
    478 S.W.3d 172
    , 185 (Tex. App.—Houston [1st Dist.] 2015,
    pet. denied). The critical inquiry is “whether the expert’s expertise goes to the very
    matter on which he or she is to give an opinion.” Broders v. Heise, 
    924 S.W.2d 148
    ,
    153 (Tex. 1996); see Mangin v. Wendt, 
    480 S.W.3d 701
    , 707 (Tex. App.—Houston
    [1st Dist.] 2015, no pet.).
    Also, a physician may be qualified to provide an expert report even if his
    specialty differs from that of the defendant if he “has practical knowledge of what is
    usually and customarily done by other practitioners under circumstances similar to
    those confronting the malpractice defendant,” or “if the subject matter is common to
    and equally recognized and developed in all fields of practice.” Keo v. Vu, 
    76 S.W.3d 725
    , 732 (Tex. App.—Houston [1st Dist.] 2002, pet. denied). “‘[T]he applicable
    ‘standard of care’ and an expert’s ability to opine on it are dictated by the medical
    condition involved in the claim and by the expert’s familiarity and experience with
    that condition.’” Lee v. Le, No. 01-18-00309-CV, 
    2018 WL 4923938
    , at *4 (Tex.
    App.—Houston [1st Dist.] Oct. 11, 2018, no pet.) (mem. op.) (quoting Barber v.
    Dean, 
    303 S.W.3d 819
    , 826 (Tex. App.—Fort Worth 2009, no pet.)).
    As stated in Dr. Mitchell’s report, he has treated, performed surgery on, and
    managed the care of many patients with diabetic foot wounds, and he therefore is
    11
    familiar with the accepted standards of medical care for the treatment of patients like
    Milner. He further explains that the applicable standards of care “are standards basic
    to the general practice of medicine that any general practitioner or resident treating
    diabetic patients with foot infections should know.” Based on these statements alone,
    the trial court could have reasonably concluded that Dr. Mitchell was qualified to
    provide standard-of-care opinions under the explicit provisions of section 74.401.
    See Lee, 
    2018 WL 4923938
    , at *4; Armenta v. Jones, No. 01-17-00439-CV, 
    2018 WL 1095388
    , at *4–5 (Tex. App.—Houston [1st Dist.] Mar. 1, 2018, no pet.) (mem.
    op.).
    Additionally, this court recently reiterated that the care and treatment of an
    open wound and infection are common to and equal in all fields of medicine,1 which
    comports with Dr. Mitchell’s opinion:
    Here, the subject matter of the claim against Dr. Clavijo involves
    the standards of care in the treatment of an open wound and the
    prevention of infection. “[T]he care and treatment of open wounds and
    the prevention of infection are subjects common to and equally
    recognized and developed in all fields of practice, thus any physician
    familiar with and experienced in the subject may testify as to the
    standard of care.”; . . .

    (Tex. App.—San Antonio Feb. 18, 2015, no pet.) (mem. op.).2
    The trial court did not abuse its discretion in finding that Dr. Mitchell’s report
    established his qualifications to opine on the standard of care applicable to Dr.
    Balasubramanian. See 
    id. at *6–9
    (holding that trial court did not abuse its discretion
    in concluding cardiologist was qualified to testify on standard of care applicable to
    internist for treatment of open wound and infection prevention). We overrule Dr.
    Balasubramanian’s first issue.
    Standard of Care and Breach
    An expert report must provide a “fair summary” of the expert’s opinions
    regarding the (1) applicable standards of care, (2) manner in which the care rendered
    by the physician or health care provider failed to meet the standards, and (3) causal

    Dr. Balasubramanian. Dr. Balasubramanian’s second issue asserts that Dr.
    Mitchell’s report failed to provide a sufficient opinion on the applicable standard of
    care and breach.
    Regarding the standard of care applicable to Dr. Balasubramanian (and to Dr.
    Nguyen, who does not contest the standard of care and breach in this appeal) and its
    breach by Dr. Balasubramanian, Dr. Mitchell’s report states:
    An infected foot in the presence of a foreign body in a diabetic patient
    is a surgical emergency. Surgical exploration with removal of the
    foreign body and surgical debridement should be done as soon as
    possible after the diagnosis is made, and within 24 hours at the latest.
    This is because the development and progression of the infected wound
    is often complicated by diabetic changes, such as neuropathy and
    vascular disease. Without early intervention, the wound can rapidly
    deteriorate, leading to amputation of the affected limb. Therefore, it is
    at this crucial early stage that physicians have the potential to curb what
    is often progression from mild infection to a more severe problem, with
    14
    necrosis, gangrene and often amputation. If there is any doubt regarding
    diagnosis of peripheral vascular disease, the patient should be referred
    to a specialist for a full vascular assessment.
    After surgical debridement, frequent wound assessment and bacterial
    control and moisture balance is required to prevent maceration and
    infection. Additionally, infection control and restoring pulsatile blood
    flow is critical for healing of the wound. This requires a team approach.
    Documentation of the size of the wound is important to determine if the
    wound is healing and the treatment plan is working. Debridement may
    be a one-off procedure or it may need to be ongoing for maintenance of
    the wound bed. The requirement for further debridement should be
    determined each day following changing of dressings. [Emphases
    added.].
    In stating his opinion on the applicable standard of care, Dr. Mitchell’s report
    states with sufficient detail what a physician should have done and explains why it
    was the standard of care; it provides “enough information” for the trial court to have
    concluded that the report constitutes a good-faith effort to set forth the applicable
    standard of care as to Dr. Balasubramanian. See 
    Miller, 536 S.W.3d at 517
    ; see also
    
    Baty, 543 S.W.3d at 696
    –97.
    Dr. Balasubramanian’s actual complaint about Dr. Mitchell’s standard-of-care
    opinion is that Dr. Mitchell insufficiently explains why his articulated standard of
    care applies to Dr. Balasubramanian, an internist. This is a reiteration of Dr.
    Balasubramanian’s argument on Dr. Mitchell’s qualifications to provide a standard-
    of-care opinion as to Dr. Balasubramanian. We rejected that argument above and
    reject this reiteration for the same reason.
    15
    Next, we address Dr. Balasubramanian’s assertion that Dr. Mitchell’s report
    insufficiently addresses Dr. Balasubramanian’s breach of the standard of care. The
    section of Dr. Mitchell’s report concerning Dr. Balasubramanian’s breach of the
    standard of care states:
    An attending physician, and certainly an internist must be aware that an
    infected foot in the presence of a foreign body in a diabetic patient is a
    surgical emergency. Ms. Milner should have undergone surgical
    exploration with removal of the foreign body and wide surgical
    debridement as soon as possible after her March 22nd admission to the
    hospital, and within 24 hours at the latest. Dr. Balasubramanian
    breached the standard of care by waiting until March 24, 2015 to
    request a consult with a surgeon. The delay in getting Ms. Milner to
    surgery put her entire leg at risk for amputation and was a proximate
    cause of the great toe amputation, as well as, her long and protracted
    recovery and hospitalization. This is because diabetic foot wounds are
    known to rapidly deteriorate. By the time Dr. Balasubramanian referred
    Ms. Milner to surgery, her wound had become more necrotic and
    difficult to manage.
    After the March 25, 2015 surgery, it does not appear from the medical
    records that Dr. Balasubramanian examined the wound until March 30,
    2015 when Ms. Milner was scheduled to be discharged. At that point,
    it was discovered that Ms. Milner had a gangrenous diabetic left foot
    infection. Dr. Balasubramanian breached the standard of care by failing
    to follow-up and assess the condition of the wound. The lack of
    physician follow-up following surgery put Ms. Milner’s entire leg at
    risk for amputation and was a proximate cause of the great toe
    amputation, as well as, her long and protracted recovery and
    hospitalization. As stated above, diabetic foot wounds can, and do,
    rapidly deteriorate and must be managed in a timely and effective way
    with tissue debridement, inflammation and infection control, and
    moisture balance. A physician cannot simply abandon the patient
    following surgery and hope for the best.
    On March 23, 2015 it was noted that Ms. Milner’s pulse in the affected
    left foot was difficult to palpate. At this time, Dr. Balasubramanian
    16
    should have called into question Ms. Milner’s vascular status given her
    history of diabetes and ordered a vascular consult. This was critical to
    prevent any complications associated with ischemia. Dr.
    Balasubramanian breached the standard of care by waiting until March
    30, 2015 to order a vascular consult. This too put Ms. Milner’s entire
    leg at risk for amputation and was a proximate cause of the great toe
    amputation, as well as, her long and protracted recovery and
    hospitalization. This is because treating any severe ischemia is critical
    to wound healing, regardless of other interventions. Early referral to a
    vascular specialist likely would have resulted in earlier arterial
    reconstruction to improve blood flow and improve healing of the
    wound, which would have substantially reduced the risk of amputation.
    Timely and effective wound management in this case, as described
    above, likely would have prevented the need for amputation of Vickie
    Milner’s great toe.
    In summary, Dr. Mitchell opined that Dr. Balasubramanian: (1) failed to
    timely consult with a surgeon so that Milner could have undergone surgical
    exploration, with removal of the foreign body and wide surgical debridement,
    within 24 hours of admission; (2) failed to request a vascular consult when the pulse
    in Milner’s affected foot was difficult to palpate; and (3) failed to follow up and
    assess the condition of the wound in the five days between surgery and her
    scheduled discharge.
    Regarding Dr. Mitchell’s opinion that Dr. Balasubramanian breached the
    standard of care by failing to obtain a surgical consultation until two days after
    Milner’s admission, Dr. Balasubramanian asserts that the medical records reflect that
    he ordered the surgical consultation “within the relevant timeframe.” As stated
    above, our review of the adequacy of Dr. Mitchell’s report is limited to the four
    17
    corners of his report. Bowie Mem’l 
    Hosp., 79 S.W.3d at 52

    or the facts upon which the expert bases such opinions, but to act as a gatekeeper in
    evaluating the sufficiency of the report itself. 
    Mettauer, 326 S.W.3d at 691
    . Further,
    a “court may not consider an expert’s credibility, the data relied upon by the expert,

    , 562
    (Tex. App.—Houston [1st Dist.] 2018, no pet.). Thus, at this preliminary stage, a
    court does not determine an alleged factual dispute about the underlying medical
    records or the health care at issue. See id.; Holt v. Holt, No. 01-17-00008-CV,

    Dr. Mitchell’s opinion is that Milner’s infected foot was a surgical emergency,
    that she needed surgery within 24 hours at the latest, and that Dr. Balasubramanian
    breached the standard of care by failing to obtain a surgical consultation until two
    days after Milner’s admission. Dr. Mitchell concluded or inferred from the medical
    records that Dr. Balasubramanian ordered a surgical consultation with Dr. Nguyen
    on March 24, 2015, two days after Milner was admitted to the Medical Center.
    Dr. Balasubramanian next contends that Dr. Mitchell does not describe how
    Dr. Balasubramanian failed to follow up and assess the condition of Milner’s wound
    after the March 25 surgery. We disagree; according to Dr. Mitchell’s report, after
    the March 25 surgery, “it does not appear from the medical records that Dr.
    Balasubramanian examined the wound until March 30, 2015 when Ms. Milner was
    scheduled to be discharged. At that point, it was discovered that Ms. Milner had a
    gangrenous diabetic left foot infection.”
    Lastly, Dr. Balasubramanian asserts that Dr. Mitchell’s opinion that Dr.
    Balasubramanian failed to request a vascular consult is too vague because of Dr.
    Mitchell’s statement that if “there is any doubt regarding diagnosis of peripheral
    vascular disease, the patient should be referred to a specialist for a full vascular
    19
    assessment.” But a court reviews the report “in its entirety,” 
    Baty, 543 S.W.3d at 695
    , and Dr. Mitchell clarifies later in his report:
    On March 23, 2015 it was noted that Ms. Milner’s pulse in the affected
    left foot was difficult to palpate. At this time, Dr. Balasubramanian
    should have called into question Ms. Milner’s vascular status given her
    history of diabetes and ordered a vascular consult. This was critical to
    prevent any complications associated with ischemia. Dr.
    Balasubramanian breached the standard of care by waiting until March
    30, 2015 to order a vascular consult.
    “More detail” is not required at this stage. See 
    id. at 696;
    Lee, 
    2018 WL 4923938
    , at *5. Dr. Mitchell’s report sufficiently identifies the “conduct being called
    into question.” 
    Baty, 543 S.W.3d at 697
    ; see 
    Palacios, 46 S.W.3d at 875
    . Dr.
    Mitchell’s report on the standard of care and its breaches informs Dr.
    Balasubramanian of the specific conduct being called into question and provided the
    trial court with a basis to conclude that Milner’s claim has merit; it therefore satisfies
    the good-faith effort required by the statute. See 
    id. We overrule
    Dr.
    Balasubramanian’s second issue.
    Cypress Fairbanks Medical Center. In its sole issue, the Medical Center
    contends in part that Dr. Mitchell’s report failed to provide the necessary fair
    summary of the standard of care applicable to its nursing staff and the breach of the
    standard of care. Regarding the standard of care applicable to the Medical Center’s
    nursing staff and its breach, Dr. Mitchell’s report states:
    After surgical debridement frequent wound assessment and bacterial
    control and moisture balance is required to prevent maceration.
    20
    Additionally, infection control and restoring pulsatile blood flow is
    critical for healing of the wound. This requires a team approach. A
    physician may only see the patient once or twice per day and relies on
    the wound care nursing staff to document the condition of the wound.
    Documentation of the size of the wound is important to determine if the
    wound is healing and the treatment plan is working. Recording the size,
    depth, appearance and location of the wound establishes a baseline for
    treatment, and monitoring any response to interventions. The wound
    care nursing staff must notify physicians if the wound is deteriorating.
    Debridement may be a one-off procedure or it may need to be ongoing
    for maintenance of the wound bed. The requirement for further
    debridement should be determined after each dressing change. This can
    only occur with prompt communication between the wound care
    nursing team and the treating physicians. Once the wound progresses
    to the state of gangrene, it is often too late to curb life threatening
    infection without amputation of the affected limb.
    ....
    In the days following the March 25th surgery there appears to have been
    little or no documented wound care or follow-up of the condition of the
    wound. The nurses and wound technicians at Cypress Fairbanks
    Medical Center breached the standard of care by failing to timely
    provide wound care and assessment following the March 25, 2015
    surgery, and by failing to timely report the declining condition of Ms.
    Milner’s wound to physicians allowing same to become gangrenous by
    March 30, 2015. The failure to timely provide wound care and alert
    physicians of the declining condition of the wound following the March
    25, 2016 surgery put Ms. Milner’s entire leg at risk for amputation and
    was a proximate cause of the great toe amputation, as well as, her long
    and protracted recovery and hospitalization. This is because diabetic
    foot wounds can, and do, rapidly deteriorate in light of diabetic
    changes, such as neuropathy and vascular disease. Once the wound
    progresses to the state of gangrene, it is often too late to curb life
    threatening infection without amputation of the affected limb.
    Therefore, the wound must be managed in a timely and effective way
    with tissue debridement, inflammation and infection control, and
    moisture balance. This requires a team approach, including prompt
    communication with the treating physicians when the wound is not
    healing as desired. Timely and effective wound management, including
    21
    communication with physicians when the wound was declining, likely
    would have prevented the need for amputation of Ms. Milner’s great
    toe. [Emphases added.].
    “The standard of care is defined by what an ordinarily prudent healthcare
    provider would have done under the same or similar circumstances.” Clavijo, 
    2018 WL 2976116
    , at *13 (citing 
    Palacios, 46 S.W.3d at 880
    ); see Peabody v. Manchac,
    No. 14-17-00646-CV, — S.W.3d —, —, 
    2018 WL 6836864
    , at *3 (Tex. App.—
    Houston [14th Dist.] Dec. 27, 2018, no pet. h.).
    The Medical Center argues that Dr. Mitchell’s opinion on the applicable
    standard of care and its breach lacks the specificity and detail required to satisfy the
    fair-summary standard. We disagree. Dr. Mitchell opined that the Medical Center’s
    nursing staff should have: (1) performed frequent wound assessment;
    (2) documented the condition of the wound; and (3) promptly notified physicians if
    the wound was deteriorating. Dr. Mitchell then opined that the Medical Center
    nurses and wound technicians breached the standard of care by (1) failing to timely
    provide wound care and assessment; (2) failing to document the condition of the
    wound; and (3) failing to timely report the declining condition of the wound to
    physicians. Dr. Mitchell’s opinions are supported by his statement that, from the
    medical records, “there appears to have been little or no documented wound care or
    follow-up of the condition of the wound” in the days following the March 25 surgery
    22
    and by the fact that Milner’s wound had become gangrenous by March 30, which
    was discovered only as she was being discharged and picked up by her daughter.
    Dr. Mitchell could infer the standard-of-care breaches from the lack of
    documentation in the medical records and the gangrenous condition on March 30.
    See Hood, 
    2012 WL 4465357
    , at *5–6 (holding expert could infer from lack of
    documentation in medical records that thorough wound cleaning did not occur and
    breached standard of care); Azle Manor, Inc. v. Vaden, No. 02-08-00115-CV, 
    2008 WL 4831408
    , at *6 (Tex. App.—Fort Worth Nov. 6, 2008, no pet.) (mem. op.)
    (holding expert could draw inferences from what was not in patient’s medical
    records), overruled in part on other grounds by Certified EMS, Inc. v. Potts, 
    392 S.W.3d 625
    (Tex. 2013); see also Bay Oaks SNF, LLC v. Lancaster, 
    555 S.W.3d 268
    , 273–74, 280–84 (Tex. App.—Houston [1st Dist.] 2018, pet. filed) (affirming
    trial court’s approval of expert report that relied in part on lack of documentation of
    required care to prevent pressure ulcers).
    The Medical Center further argues that Dr. Mitchell’s report could have
    provided more detail:
    What is ‘timely’ under the circumstances? What sort of ‘wound’ care
    should the nurses have provided? How often should Cypress Fairbank’s
    staff have been assessing the wound? Who should have reported the
    wound’s condition to the physicians, and when should they have
    reported it?
    23
    But as Milner also correctly points out, in Hood, a similar wound-care case, this
    court rejected similar complaints. See Hood, 
    2012 WL 4465357
    , at *3–7. And as the
    supreme court stated in Baty, while an expert report can arguably provide “an
    additional degree of specificity,” “[a]dditional detail is simply not required at this
    stage of the proceedings.” 
    Baty, 543 S.W.3d at 697
    & n.10; see Lee, 
    2018 WL 4923938
    , at *5.
    Dr. Mitchell’s report on the standard of care and its breach gave the trial court
    a sufficient basis to reasonably conclude that Milner’s claims against the Medical
    Center have merit and advised the Medical Center of the conduct that Milner,
    through her expert, has called into question. 
    Baty, 543 S.W.3d at 697
    ; 
    Palacios, 46 S.W.3d at 875
    . We overrule those portions of the Medical Center’s sole issue.
    Causation
    Dr. Balasubramanian, Dr. Nguyen, and the Medical Center each contend that
    Dr. Mitchell’s report on causation is inadequate.
    For causation, the expert report must explain “how and why” the physician’s
    or healthcare provider’s breach proximately caused the plaintiff’s injury. Columbia
    Valley Healthcare Sys., L.P. v. Zamarripa, 
    526 S.W.3d 453
    , 459–60 (Tex. 2017).
    “In satisfying this ‘how and why’ requirement, the expert need not prove the entire
    case or account for every known fact; the report is sufficient if it makes ‘a good-faith
    24
    effort to explain, factually, how proximate cause is going to be proven.’” 
    Abshire, 563 S.W.3d at 224
    (quoting 
    Zamarripa, 526 S.W.3d at 460
    ).
    The report need not use the words “proximate cause,” “foreseeability,”
    or “cause in fact.” “[A] report’s adequacy does not depend on whether
    the expert uses any particular ‘magical words.’”
    ....
    Proximate cause has two components: (1) foreseeability and (2) cause-
    in-fact. For a negligent act or omission to have been a cause-in-fact of
    the harm, the act or omission must have been a substantial factor in
    bringing about the harm, and absent the act or omission—i.e., but for
    the act or omission—the harm would not have occurred.
    This is the causal relationship between breach and injury that an expert
    report must explain to satisfy the Act.
    
    Zamarripa, 526 S.W.3d at 460
    (footnoted citations omitted).
    A causation opinion must provide a “straightforward link” between the
    alleged breach of the standard of care and the claimed injury. See Abshire, 
    563 S.W.3d 225
    . The court’s role is to determine whether the expert has explained how
    the negligent conduct caused the injury. 
    Id. at 226.
    Dr. Balasubramanian. In his third issue, Dr. Balasubramanian contends that
    Dr. Mitchell’s report on causation is insufficient because it is “speculative, contains
    analytical gaps in its causal links, and relies on assumptions.” He also contends that
    Dr. Mitchell’s report only suggests that Milner’s amputation was preventable, that it
    impermissibly “works backward” from a bad outcome to establish causation, and
    that it fails to exclude other possible causes. In short, Dr. Balasubramanian argues
    25
    that Dr. Mitchell does not tie Dr. Balasubramanian’s alleged breaches to the
    outcome, resulting in an “impermissible analytical gap” and lack of sufficient
    specificity to inform Dr. Balasubramanian of how his alleged breaches caused the
    outcome.
    The supreme court does not use the term “analytical gap” in the context of
    section 74.351 expert reports, but it has noted that some courts of appeals do.3
    
    Abshire, 563 S.W.3d at 225
    , n.10.
    It appears that the courts have generally used this term to mean a failure
    to link the breach of the standard of care to the injury, which comports
    with this Court’s discussion of chapter 74’s expert report requirements
    with respect to causation. See 
    Zamarripa, 526 S.W.3d at 460
    (holding
    that an expert report sufficiently addresses causation where it
    “explain[s] the basis of [the expert’s] statements to link [the]
    conclusions to the facts”).
    
    Id. We will
    follow the supreme court and decline to analyze the causation issue with
    the term “analytical gap.”
    Dr. Balasubramanian’s assertion that Dr. Mitchell’s report has a fatal one-
    week gap concerning Milner’s care between March 25 and March 30 is premature.
    Cf. 
    Puppula, 564 S.W.3d at 201
    (“But the absence of an opinion stating with
    specificity at what point in the continuum of disease progression an intervention
    3
    The term arose from and is used in the area of expert-opinion reliability. See
    Gammill v. Jack Williams Chevrolet, Inc., 
    972 S.W.2d 713
    , 726–27 (Tex.
    1998) (deeming expert testimony unreliable when “there is simply too great
    an analytical gap between the data and the opinion proffered”).
    26
    would have proven timely does not cause these experts’ causation opinion to be
    conclusory at this early stage of evaluation.”). Further, Dr. Mitchell was not required
    to exclude or rule out other possible causes of Milner’s injuries in his expert report.
    
    Curnel, 562 S.W.3d at 562
    (quoting Baylor Med. Ctr v. Wallace, 
    278 S.W.3d 552
    ,
    562 (Tex. App.—Dallas 2009, no pet.) (“Nothing in section 74.351 suggests the
    preliminary report is required to rule out every possible cause of the injury, harm, or
    damages claimed.”)).
    Regarding Dr. Balasubramanian’s alleged failure to timely consult with a
    surgeon so that Milner could have undergone surgery within 24 hours of admission,
    Dr. Mitchell’s report explains “how and why” this failure caused the amputation of
    her great toe. It first states that a diabetic patient’s foot infection is a “surgical
    emergency” that requires surgical treatment within 24 hours because “diabetic foot
    wounds are known to rapidly deteriorate.” “Without early intervention, the wound
    can rapidly deteriorate, leading to amputation of the affected limb. Therefore, it is at
    this crucial early stage that physicians have the potential to curb what is often
    progression from mild infection to a more severe problem, with necrosis, gangrene
    and often amputation.”
    As a result, Dr. Mitchell then opines, the “delay in getting Ms. Milner to
    surgery put her entire leg at risk for amputation and was a proximate cause of the
    great toe amputation, as well as, her long and protracted recovery and
    27
    hospitalization.”4 To further support his opinion that Dr. Balasubramanian’s delayed
    surgical consultation was a cause of the great-toe amputation, Dr. Mitchell notes that
    at the time of the allegedly delayed surgery, the “dorsal tissue on the plantar aspect
    of the great toe was found to be blackish” by the surgeon, Dr. Nguyen. Dr. Mitchell
    concludes that Dr. Balasubramanian’s breach “was a proximate cause of Ms.
    Milner’s amputation and long and protracted recovery and hospitalization. I am of
    the medical opinion that Ms. Milner more likely than not would not have required
    amputation and extended hospitalization with prompt and proper care and
    assessment of the wound as described above.”
    Dr. Mitchell sufficiently addresses foreseeability. In explaining why a
    diabetic’s foot infection with a foreign body is a surgical emergency, he states that
    “diabetic foot wounds are known to rapidly deteriorate,” further explaining that this
    is “because the development and progression of the infected wound is often
    complicated by diabetic changes, such as neuropathy and vascular disease.”
    Dr. Mitchell sufficiently describes the causal relationship because he explains
    the factual basis for his opinions and he links Dr. Balasubramanian’s alleged
    conduct—the      delayed    surgical   consultation—with      Milner’s    subsequent
    development of gangrene and the amputation. See Peabody, — S.W.3d at —, 2018
    4
    While not required, see 
    Zamarripa, 526 S.W.3d at 460
    , Dr. Mitchell’s report
    contains and relies on an accurate definition of proximate cause.
    
    28 WL 6836864
    , at *7, 14; Clavijo, 
    2018 WL 2976116

    2017 WL 3483211
    , at *4; Hood, 
    2012 WL 4465357
    , at *6. This causation opinion provides
    the “how and why” and a “straightforward link” between the alleged breach of the
    standard of care and the claimed injury. See 
    Abshire, 563 S.W.3d at 225
    ; Peabody,
    — S.W.3d at —, 
    2018 WL 6836864
    , at *7, 14.
    Regarding Dr. Balasubramanian’s alleged failure to request a vascular
    consultation when the pulse in Milner’s affected foot was difficult to palpate on
    March 23, Dr. Mitchell’s report explains that this “too put Ms. Milner’s entire leg at
    risk for amputation and was a proximate cause of the great toe amputation, as well
    as, her long and protracted recovery and hospitalization.” As part of foreseeability,
    he explains why: “[T]reating any severe ischemia is critical to wound healing,
    regardless of other interventions. Early referral to a vascular specialist likely would
    have resulted in earlier arterial reconstruction to improve blood flow and improve
    healing of the wound, which would have substantially reduced the risk of
    amputation.” And again, his report states elsewhere that “the development and
    progression of the infected wound is often complicated by diabetic changes, such as
    neuropathy and vascular disease.”
    Dr. Mitchell sufficiently describes the causation element pertaining to Dr.
    Balasubramanian’s alleged failure to request a vascular consultation. Dr. Mitchell
    explains the factual basis for his opinions and links Dr. Balasubramanian’s failure
    29
    to request a vascular consultation with Milner’s subsequent development of
    gangrene and the amputation. See Peabody, — S.W.3d at —, 
    2018 WL 6836864
    , at
    *14 (concluding “it is reasonable to anticipate the consulting specialist doctor would
    comply with the standard of care”). This causation opinion likewise provides the
    “how and why” and a “straightforward link” between the alleged breach of the
    standard of care and the claimed injury.5
    Because Dr. Mitchell’s expert report adequately links his conclusions with the
    underlying facts, the trial court could have reasonably concluded that it constitutes
    an objective, good-faith effort to provide a fair summary of his opinions with respect
    to the causal relationship between Dr. Balasubramanian’s alleged breaches and
    Milner’s injury. See 
    Abshire, 563 S.W.3d at 225
    –26; Peabody, — S.W.3d at —,
    
    2018 WL 6836864
    , at *7, 14. We overrule Dr. Balasubramanian’s third issue.
    Dr. Nguyen. In his sole issue, Dr. Nguyen asserts that Dr. Mitchell’s
    causation opinions are conclusory and contain an “analytical gap” or “missing link.”
    Dr. Mitchell’s standard-of-care and causation opinions as to Dr. Nguyen are as
    follows:
    5
    If an expert report adequately addresses at least one liability theory, it satisfies
    the statutory requirements. See Certified EMS, Inc. v. Potts, 
    392 S.W.3d 625
    ,
    630–32 (Tex. 2013). Because we have found two of Milner’s negligence
    theories in Dr. Mitchell’s expert report against Dr. Balasubramanian to be
    adequate, we need not further address the allegation that Dr. Balasubramanian
    failed to follow up and assess the condition of the wound in the five days
    between surgery and Milner’s scheduled discharge.

    Dr. Nguyen noted in his March 25, 2015 operative report that due to
    her diabetes, Ms. Milner was at high risk for possibly eventually losing
    her toes due to poor circulation. Nevertheless, he breached the standard
    of care by failing to refer her to [a] vascular specialist to manage any
    ischemia. This put Ms. Milner’s entire leg at risk for amputation and
    was a proximate cause of the great toe amputation, as well as, her long
    and protracted recovery and hospitalization. This is because treating
    any severe ischemia is critical to wound healing, regardless of other
    interventions. Early referral to a vascular specialist likely would have
    resulted in earlier arterial reconstruction to improve blood flow and
    improve healing of the wound, which would have substantially reduced
    the risk of amputation.
    Between March 25th and March 30th (following the debridement
    procedure) it does not appear from the medical records that Dr. Nguyen
    ever examined the wound. On March 30, 2015, it was discovered that
    Ms. Milner had a gangrenous diabetic left foot infection. Dr. Nguyen
    breached the standard of care by failing to follow-up and assess the
    condition of the wound. The lack of physician follow-up following
    surgery put Ms. Milner’s entire leg at risk for amputation and was a
    proximate cause of the great toe amputation, as well as, her long and
    protracted recovery and hospitalization. This is because diabetic foot
    wounds can, and do, rapidly deteriorate and must be managed in a
    timely and effective way with tissue debridement, inflammation and
    infection control, and moisture balance. Frequent wound assessment
    and bacterial control and moisture balance is required to prevent
    maceration. Debridement may need to be repeated for maintenance of
    the wound bed. The requirement for further debridement should be
    determined after each dressing change. A physician cannot simply
    abandon the patient following surgery and hope for the best. Timely
    and effective wound management in this case likely would have
    prevented the need for amputation of Ms. Milner’s great toe.
    Dr. Nguyen relies on Humble Surgical Hospital, LLC v. Davis, 
    542 S.W.3d 12
    (Tex. App.—Houston [14th Dist.] 2017, pet. filed), to support his causation
    31
    argument. We find this opinion unpersuasive for several reasons.6 First, it largely
    relies on the “analytical gap” argument in the Beaumont Court’s opinion in Abshire,
    which has been reversed. 
    Id. at 23–26
    (citing HealthSouth Rehabilitation Hosp. of
    Beaumont, LLC v. Abshire, 
    561 S.W.3d 193
    , 214–17 (Tex. App.—Beaumont 2017),
    rev’d, 
    563 S.W.3d 219
    (Tex. 2018)). It is therefore questionable whether the
    Fourteenth Court’s opinion in Humble Surgical comports with the supreme court’s
    direction in Abshire on the review of causation reports:
    Dr. Rushing explained how the nurses’ breach—failing to consistently
    document Abshire’s OI, particularly in light of her continued
    complaints of back pain—caused a delay in diagnosis and proper
    treatment and why that delay caused the issues that led to Abshire’s
    paraplegia. Thus, the report adequately explained the links in the causal
    chain.
    Despite this identified causal link, the court of appeals held that
    the report was conclusory because it “fail[ed] to explain how the nurses’
    alleged failure to document OI was a substantial factor in causing or
    exacerbating Abshire’s injuries . . . or that it would have changed the
    
    outcome.” 562 S.W.3d at 217
    . Specifically, the court observed that the
    physicians did not order tests or provide spinal treatment on either the
    November 22 or 23 visits, even though Abshire’s OI was noted during
    these visits. See 
    id. at —.
    Therefore, the court held that Dr. Rushing’s
    “opinion that the nurses’ failure to chart Abshire’s history of OI caused
    Abshire’s injury rests on an analytic gap that renders his causation
    opinion as to the nurses conclusory.” 
    Id. at 201.
    We disagree that such an analytic gap exists. As explained above,
    Dr. Rushing’s report adequately links his conclusion with the

    The plaintiff’s petition for review in Humble Surgical is pending before the
    supreme court, and briefing on the merits was requested and has been
    completed. See Davis v. Humble Surgical Hosp., LLC, No. 18-0092 (Tex.),
    Petition for Review, filed Feb. 2, 2018.
    32
    underlying facts (failure to properly document Abshire’s medical
    history was a substantial factor in her delayed treatment and subsequent
    injury). Rather, it appears the court of appeals simply did not agree with
    his conclusions in light of Abshire’s overall course of treatment.
    However, the court’s job at this stage is not to weigh the report’s
    credibility; that is, the court’s disagreement with the expert's opinion
    does not render the expert report conclusory.
    ....
    In the same vein, with respect to causation, the court’s role is to
    determine whether the expert has explained how the negligent conduct
    caused the injury. Whether this explanation is believable should be
    litigated at a later stage of the proceedings.
    The ultimate evidentiary value of the opinions proffered by Dr.
    Rushing and Nurse Aguirre is a matter to be determined at summary
    judgment and beyond. In this regard, the court of appeals improperly
    examined the merits of the expert’s claims when it identified what it
    deemed an “analytical gap.”

    Additionally, Peabody, a subsequent Fourteenth Court opinion that applied
    the supreme court’s Abshire opinion, is persuasive. See Peabody, — S.W.3d at —,
    
    2018 WL 6836864
    , at *6, 8–11 (“The Texas Supreme Court recently approved a
    causation opinion in a similar expert report . . . . We look to the cases relied on by
    St. Luke’s with this more recent test in mind.”) (citing 
    Abshire, 563 S.W.3d at 225
    –

    the experts’ causation opinions met the test in Abshire. See

    We have addressed Dr. Mitchell’s causation opinion as to Dr.
    Balasubramanian’s alleged failure to request a vascular consultation. For the same
    reasons, we conclude that Dr. Mitchell’s causation opinion as to Dr. Nguyen
    constitutes an objective, good-faith effort to provide a fair summary of his opinions
    with respect to the causal relationship between Dr. Nguyen’s alleged breach and
    Milner’s injury.7 We overrule Dr. Nguyen’s sole issue.
    Cypress Fairbanks Medical Center. The Medical Center contends in the last
    part of its sole issue that Dr. Mitchell’s report failed to explain how its nursing staff
    caused Milner’s injury.
    Dr. Mitchell’s report states the following on causation as to the Medical
    Center:
    In the days following the March 25th surgery there appears to have been
    little or no documented wound care or follow-up of the condition of the
    wound. The nurses and wound technicians at Cypress Fairbanks
    Medical Center breached the standard of care by failing to timely
    provide wound care and assessment following the March 25, 2015
    surgery, and by failing to timely report the declining condition of Ms.
    Milner’s wound to physicians allowing same to become gangrenous by
    March 30, 2015. The failure to timely provide wound care and alert
    physicians of the declining condition of the wound following the March
    25, 2016 surgery put Ms. Milner’s entire leg at risk for amputation and
    was a proximate cause of the great toe amputation, as well as, her long
    and protracted recovery and hospitalization. This is because diabetic
    foot wounds can, and do, rapidly deteriorate in light of diabetic
    7
    As we did with Dr. Balasubramanian, we similarly need not address Dr.
    Nguyen’s causation argument on his alleged failure to follow up and assess
    the condition of the wound in the five days between surgery and Milner’s
    scheduled discharge.

    changes, such as neuropathy and vascular disease. Once the wound
    progresses to the state of gangrene, it is often too late to curb life
    threatening infection without amputation of the affected limb.
    Therefore, the wound must be managed in a timely and effective way
    with tissue debridement, inflammation and infection control, and
    moisture balance. This requires a team approach, including prompt
    communication with the treating physicians when the wound is not
    healing as desired. Timely and effective wound management, including
    communication with physicians when the wound was declining, likely
    would have prevented the need for amputation of Ms. Milner’s great
    toe. [Emphases added.].
    Regarding the Medical Center’s standard of care, Dr. Mitchell’s report states
    the following, which also pertains to causation:
    A physician may only see the patient once or twice per day and relies
    on the wound care nursing staff to document the condition of the wound.
    Documentation of the size of the wound is important to determine if the
    wound is healing and the treatment plan is working. Recording the size,
    depth, appearance and location of the wound establishes a baseline for
    treatment, and monitoring any response to interventions. The wound
    care nursing staff must notify physicians if the wound is deteriorating.
    Debridement may be a one-off procedure or it may need to be ongoing
    for maintenance of the wound bed. The requirement for further
    debridement should be determined after each dressing change. This can
    only occur with prompt communication between the wound care
    nursing team and the treating physicians. Once the wound progresses
    to the state of gangrene, it is often too late to curb life threatening
    infection without amputation of the affected limb. [Emphases added.].
    Dr. Mitchell concludes: “It is my opinion that Cypress Fairbanks Medical
    Center failed to use ordinary care in its treatment of Vickie Milner by failing to
    provide timely and appropriate wound care and wound assessment; and by failing to
    alert physicians of the declining condition of the wound.” He then includes the
    35
    Medical Center with the physicians in his causation conclusion, stating that the
    Medical Center’s negligence (breach) “was a proximate cause of Ms. Milner’s
    amputation and long and protracted recovery and hospitalization. I am of the medical
    opinion that Ms. Milner more likely than not would not have required amputation
    and extended hospitalization with prompt and proper care and assessment of the
    wound as described above.” (Emphasis added).
    Specifically, the Medical Center asserts that Dr. Mitchell’s report (1) does not
    explain how the nursing staff’s providing wound care would have halted the progress
    of Milner’s infection; (2) does not explain how the nursing staff would have
    anticipated that, as a result of their failure to provide proper wound care and
    management, the physicians would not themselves evaluate and manage Milner’s
    wound; (3) does not explain how alerting physicians would have changed the
    outcome and prevented Milner’s toe amputation; (4) does not show at what point in
    the timeline that alerting physicians would have allowed them to intervene to prevent
    the amputation; (5) does not explain how additional information from the nursing
    staff would have led the physicians to curb the progression of Milner’s infection if
    the physicians already had that information; and (6) requires the court to assume that
    the nursing staff’s communication to a physician would have caused the physician
    to take action that would have prevented the amputation.
    36
    The Medical Center contends that Dr. Mitchell does not explain how wound
    care would have halted the progression of Milner’s infection, and it makes the related
    contention that his report does not explain how alerting physicians would have
    changed the outcome and prevented Milner’s toe amputation. We disagree; his report
    states:
    Without early intervention, the wound can rapidly deteriorate, leading
    to amputation of the affected limb. Therefore, it is at this crucial early
    stage that physicians have the potential to curb what is often
    progression from mild infection to a more severe problem, with
    necrosis, gangrene and often amputation.
    ....
    Documentation of the size of the wound is important to determine if the
    wound is healing and the treatment plan is working. Recording the size,
    depth, appearance and location of the wound establishes a baseline for
    treatment, and monitoring any response to interventions. The wound
    care nursing staff must notify physicians if the wound is deteriorating.

    [D]iabetic foot wounds can, and do, rapidly deteriorate in light of
    diabetic changes, such as neuropathy and vascular disease. Once the
    wound progresses to the state of gangrene, it is often too late to curb
    life threatening infection without amputation of the affected limb.
    Therefore, the wound must be managed in a timely and effective way
    with tissue debridement, inflammation and infection control, and
    moisture balance. This requires a team approach, including prompt
    communication with the treating physicians when the wound is not
    healing as desired. Timely and effective wound management, including
    communication with physicians when the wound was declining, likely
    would have prevented the need for amputation of Ms. Milner’s great
    toe. [Emphases added].
    37
    The Medical Center makes another related argument that Dr. Mitchell does
    not explain when alerting Milner’s physicians would have allowed them to intervene
    to prevent the amputation. But as we have already noted, the absence of such an
    opinion in an expert report at this early stage does not render the report deficient.
    See 
    Puppala, 564 S.W.3d at 201
    .
    Next, and relying in part on Curnel, the Medical Center contends that Dr.
    Mitchell does not explain how the nursing staff would have anticipated that, as a
    result of their failure to provide proper wound care and management, the physicians
    themselves would not evaluate and manage Milner’s wound, especially since Dr.
    Mitchell states that “physicians have the potential to curb what is often progression
    from mild infection to a more severe problem, with necrosis, gangrene and often
    amputation.” Dr. Mitchell’s report does explain this alleged omission. He states that
    wound care and management is a “team approach,” that the wound care nursing staff
    should document the “size, depth, appearance and location of the wound” and
    monitor the wound’s response to interventions, and that the physician “relies on the
    wound care nursing staff to document the condition of the wound.” As for Curnel,
    it is inapposite because it concluded that the causation report was deficient on cause-
    in-fact because the report stated that the subsequent treating physicians did have the
    additional information that the nursing staff allegedly failed to provide to them so
    that they could make the correct diagnosis. See 
    Curnel, 562 S.W.3d at 567
    –68. And
    38
    Christus Health Gulf Coast v. Davidson, No. 15-15-00643-CV, 
    2016 WL 2935715
    ,
    at *5 (Tex. App.—Houston [14th Dist.] May 17, 2016, no pet.) (mem. op.), also
    relied on by the Medical Center, is inapposite for the same reason.
    The Medical Center’s last argument relating to the nursing staff’s alleged
    failure to alert and how it would have changed the outcome is that Dr. Mitchell’s
    opinion requires the court to assume that the nursing staff’s communication to a
    physician would have caused the physician to take action that would have prevented
    the amputation.8 Peabody addressed a similar argument, concluding “it is reasonable
    to anticipate the consulting specialist doctor would comply with the standard of
    care.” Peabody, — S.W.3d at —, 
    2018 WL 6836864
    , at *14. Dr. Mitchell plainly
    states how timely communication of wound deterioration to the physician and early
    intervention could have prevented amputation, explaining that at the crucial early
    stage, “physicians have the potential to curb what is often progression from mild
    infection to a more severe problem, with necrosis, gangrene and often amputation.”
    Dr. Mitchell’s causation opinions as to the Medical Center are similar to his
    causation opinions as to Dr. Balasubramanian, which we have found sufficient. For
    the same reasons, we conclude that Dr. Mitchell sufficiently describes the causation
    element as to the Medical Center: Dr. Mitchell explains the factual basis for his
    opinions and he links the Medical Center nursing staff’s alleged conduct—failing to

    This argument largely relies on Humble Surgical, which is addressed above.

    provide timely and appropriate wound care and wound assessment and failing to
    alert physicians of the declining condition of the wound—with Milner’s subsequent
    development of gangrene and the amputation. See Peabody, — S.W.3d at —,

    , at *7; Clavijo,

    at *4; Hood, 
    2012 WL 4465357
    , at *6. Dr. Mitchell’s causation opinions provide the
    “how and why” and a “straightforward link” between the alleged breach of the
    standard of care and the claimed injury. The trial court could have reasonably
    concluded that his report constitutes an objective, good-faith effort to provide a fair
    summary of his opinions with respect to the causal relationship between the Medical
    Center’s alleged breaches and Milner’s injury. See
