    discretion in denying his request for a new trial due to erroneous evidentiary
    rulings at trial. We reverse and remand for a new trial limited to the issues
    of causation and damages.
    Appellees     developed     and    manufactured     risperidone,   an    atypical
    antipsychotic, for the treatment of schizophrenia in adult patients. In 1993,
    the Food and Drug Administration granted approval to Appellees to market
    risperidone for this purpose. Appellees brought their product to market
    under the brand name Risperdal.
    In February 2002, at the age of six, Appellant was prescribed Risperdal
    for the treatment of attention deficit disorder, attention deficit hyperactive
    disorder, and oppositional defiant disorder.2 He remained on Risperdal,
    periodically,   until   March    2007.     At   that   point   Appellant’s    physician
    discontinued Appellant’s use of the medication. At some time between 2006
    and 2008, when Appellant was ten to twelve years old, Appellant’s mother,
    M.C. (“Mrs. C”), alleged she observed Appellant suffering from unexplained

    weight gain and gynecomastia.3 However, at that time, neither Appellant nor
    Mrs. C informed Appellant’s medical providers of his condition.
    On March 14, 2013, Appellant commenced this action by filing a
    complaint. Appellant’s complaint was filed as part of the In re Risperdal®
    mass tort program, and incorporated allegations found in the master
    complaint.4 Appellant alleged his Risperdal usage caused his gynecomastia,
    and raised claims against Appellees of (I) negligence; (II) negligent design
    defect; (III) fraud; (IV) strict liability failure to warn; (V) strict liability
    design defect; (VI) breach of express warranty; (VII) breach of implied
    warranty; (VIII) violation of Pennsylvania’s Unfair Trade Practices and
    Consumer Protection Law (“UTPCPL”), 73 P.S. § 201, et. seq.; (IX) unfair
    and deceptive trade practices; (X) conspiracy; and (XI) punitive damages.
    Mrs. C asserted claims for medical expenses incurred by a parent and loss of
    consortium. Appellees denied all of Appellant’s and Mrs. C’s allegations.
    Appellees later filed a motion for partial summary judgment on the
    master docket disputing the validity of the punitive damages claim. The trial

    court granted Appellees’ motion and dismissed all plaintiffs’ claims for
    punitive damages. The trial court then denied reconsideration.
    Appellees filed a motion for summary judgment as to each count of
    Appellant’s and Mrs. C’s complaint. Appellant and Mrs. C responded,
    asserting that their claims were legally and factually sound, and therefore
    not subject to dismissal on summary judgment. The trial court granted
    Appellees’ motion in part, dismissing all claims against Appellees with the
    exception of Appellant’s negligence claim.
    Appellant’s jury trial for his remaining negligence claim began on
    February 20, 2015. Appellant offered the testimony of eleven witnesses and
    introduced approximately 200 exhibits in support of his contention that he
    developed gynecomastia as a result of Appellees’ failure to notify physicians,
    health care providers, and the FDA of the significant risk of gynecomastia
    associated with the use of Risperdal in pre-pubescent males.
    Pertinent to the instant appeal, Appellant offered the expert testimony
    of Mark Solomon, M.D. He opined Appellant suffered from gynecomastia and
    developed gynecomastia solely due to Risperdal ingestion during childhood.
    See N.T., Trial, 3/3/15, Morning Session, at 37-38, 58. At the request of
    Appellant’s counsel, Dr. Solomon performed a physical examination of
    Appellant’s chest in front of the jury to demonstrate how he determined
    Appellant was suffering from gynecomastia rather than chest enlargement
    due to obesity. See id., at 39-35. During this examination, Appellant’s
    counsel asked Dr. Solomon to analogize the amount of breast tissue
    -4-
    J-A27024-16
    Appellant had to either a softball or tennis ball. See id., at 43. Dr. Solomon
    concluded that Appellant was suffering from the presence of breast tissue
    approximately the size of a tennis ball. See id., at 44. On cross-
    examination, Dr. Solomon was asked numerous questions about Appellant’s
    visit to the emergency room in March 2013 for chest pain. Dr. Solomon
    opined that a chest examination performed in the emergency department for
    chest pain would not necessarily have led to the discovery of Appellant’s
    gynecomastia. See id., at 105-113.
    Through the introduction of seven witnesses and over eighty exhibits,
    Appellees contested every aspect of Appellant’s negligence claim. Appellees
    denied that Risperdal usage correlated to a significant risk of gynecomastia.
    They further disputed that they had negligently failed to inform physicians,
    health care providers, and the FDA of this significant risk. Further, and
    relevant to the instant appeal, Appellees heavily contested Appellant’s claim
    that he developed gynecomastia as a result of Risperdal usage. Rather,
    Appellees argued Appellant never suffered from gynecomastia, and that any
    chest enlargement was a result of weight gain.
    In support of this contention, Appellees presented the videotaped
    deposition of Michelle Baker, a physician’s assistant who treated Appellant
    from 2005 until 2013. See N.T., Trial, 2/25/15, Morning Session, at 20
    (playing deposition tape from 7/28/14); Def. Ex. 19, Baker Deposition,
    7/28/14, at 21:8-101:21. Ms. Baker opined Appellant’s breast enlargement
    was caused by his rapid weight gain, rather than his Risperdal usage. See
    -5-
    J-A27024-16
    id., at 101:5-101:21. Additionally, Appellees presented the expert testimony
    of Dr. Adelaide S. Robb and Dr. Mark Moltich. See N.T., Trial, 3/9/15,
    Morning Session, at 15-112; N.T., Trial, 3/9/15, Afternoon Session, at 5-72;
    N.T., Trial, 3/10/15, Morning Session, 15-149; N.T., Trial, 3/10/15,
    Afternoon Session, at 5-43. Dr. Moltich testified that he did not believe that
    Risperdal usage could have caused gynecomastia in Appellant. See N.T.,
    Trial, 3/10/15, Morning Session, at 86. Further, both doctors testified that
    they would expect a chest examination of a male to reveal the existence of
    breast tissue the size of a tennis ball. See N.T., Trial, 3/9/15, Morning
    Session, at 54-55; N.T., Trial, 3/10/15, Morning Session, at 66.
    Following the close of Appellees’ case, Appellees informed the trial
    court they were planning to display two tennis balls and a Power Point
    presentation during their closing argument. Appellant objected to the use of
    both visual aids. However, the trial court found that both the tennis balls and
    Power Point presentation were proper visual aids and allowed both to be
    displayed during closing arguments.
    The jury returned with a verdict in favor of Appellees. While the jury
    found Appellees negligent for failing to provide an adequate warning to
    Appellant’s prescribing physicians concerning the risk of gynecomastia
    associated with Risperdal use, they failed to find that Appellees’ negligence
    caused Appellant’s gynecomastia.
    Appellant and Mrs. C filed post-trial motions requesting a new trial, in
    which they challenged the grant of partial summary judgment. Appellant
    -6-
    J-A27024-16
    also contested the evidentiary rulings during the jury trial. The court denied
    the post-trial motions. This timely appeal follows.
    On appeal, Appellant presents the following issues5 for our review,
    which we have reordered for ease of disposition:
    1. … [D]id the trial court abuse its discretion by permitting
    [Appellees’] counsel to display two tennis balls during his
    closing?
    2. Did the trial court abuse its discretion by permitting
    [Appellees] to use in closing a 75 slide pre-prepared Power
    Point presentation: (a) that was not introduced into evidence
    during [Appellees’] case-in-chief; (b) that was not properly
    authenticated as a fair and adequate representation of that
    which it purported to represent (i.e., the evidence at trial);
    (c) that was not properly founded upon the evidence of
    record; and (d) whose effect was highly prejudicial to
    [Appellant]?
    3. Did the trial court abuse its discretion by admitting into
    evidence testimony from [Appellees’] causation experts Drs.
    Robb and Molitch, in which they opined without a factual basis
    and beyond the fair scope of their expert reports that
    [Appellant’s] gynecomastia was not caused by Risperdal
    ____________________________________________
    5 In their post-trial motions, Appellant and Mrs. C raised claims of error
    related to the trial court’s decision to dismiss all of Mrs. C’s claims and 10 of
    Appellant’s claims on summary judgment, as well as additional alleged
    errors at trial, i.e., permitting Appellees to use a Power Point in opening
    statements, permitting Appellees’ counsel to violate its time limitation during
    closing statements, and permitting Appellees’ counsel to argue that
    Appellant fraudulently brought claims during closing statements. See Post-
    Trial Motion, 5/20/15, at ¶¶ 17-28, 33, 35, 37, 41-42. However, Appellant
    appears to have abandoned these claims by failing to provide any discussion
    or citation to authority in his appellate brief. Further, Mrs. C appears to have
    dropped her appeal entirely as she does not challenge the trial court’s
    decision to dismiss both of her claims. Thus, we will not consider these
    issues.
    -7-
    J-A27024-16
    because otherwise a physical examination of [Appellant] in
    March 2013 would have revealed breasts the size of “tennis
    balls,” and the examination did not reveal “tennis ball”-sized
    breasts?
    4. Michelle Baker was a physician’s assistant who was offered at
    trial only to present fact testimony about her treatment of
    [Appellant]. Did the trial court abuse its discretion by
    admitting into evidence the deposition testimony of Ms. Baker
    designated by [Appellees], in which she offered an expert
    opinion that weight gain was the cause of [Appellant’s]
    gynecomastia?
    Appellant’s Brief, at 5 (suggested answers omitted). Based upon these
    alleged errors, Appellant contends that a new trial is warranted.
    Our standard of review is as follows:
    We will reverse a trial court’s decision to deny a motion for a
    new trial only if the trial court abused its discretion. We must
    review the court’s alleged mistake and determine whether the
    court erred, and, if so, whether the error resulted in prejudice
    necessitating a new trial. If the alleged mistake concerned an
    error of law, we will scrutinize for legal error. Once we determine
    whether an error occurred, we must then determine whether the
    trial court abused its discretion in ruling on the request for a new
    trial. An abuse of discretion exists when the trial court has
    rendered a judgment that is manifestly unreasonable, arbitrary,
    or capricious, has failed to apply the law, or was motivated by
    partiality, prejudice, bias, or ill will.
    Paliometros v. Loyola, 
    932 A.2d 128
    , 132 (Pa. Super. 2007) (internal
    citations and quotation marks omitted). See also Knowles v. Levan, 
    15 A.3d 504
    , 507 (Pa. Super. 2011).
    In his first two arguments, Appellant contends the trial court abused
    its discretion by permitting Appellees’ counsel to utilize improper visual aids
    during closing arguments. Appellant raises several different arguments
    -8-
    J-A27024-16
    based upon the trial court’s decision to allow Appellees’ counsel to present
    two tennis balls and a Power Point presentation to the jury during their
    summation. See Appellant’s Brief, at 47-55. Appellant maintains the use of
    these items was inappropriate because neither the tennis balls nor the Power
    Point presentation was entered into evidence during Appellees’ case-in chief.
    See id., at 47, 51. Further, as the Power Point presentation was not entered
    into evidence during the trial, Appellant argues the trial court failed to
    recognize that the individual slides were never authenticated. See id., at 51-
    52. Appellant thus asserts that individual slides of the Power Point
    presentation were misleading and unreliable. See id., at 52- 55.
    Our Supreme Court has held that during opening and closing
    statements,
    so long as no liberties are taken with the evidence, a lawyer is
    free to draw such inferences as he wishes from the testimony
    and to present his case in the light most suited to advance his
    cause and win a verdict in the jury box. However, this latitude
    does not include discussion of facts not in evidence which are
    prejudicial to the opposing party. In general, any prejudicial
    remarks made by counsel during argument can be handled
    within the broad powers and discretion of the trial judge and his
    actions will not be disturbed on appeal unless there is an obvious
    abuse of discretion.
    Hyrcza v. W. Penn Allegheny Health Sys., Inc., 
    978 A.2d 961
    , 977 (Pa.
    Super. 2009) (internal citations, brackets, and quotation marks omitted).
    In appropriate cases, counsel is permitted to use visual aids during
    opening and closing statements to assist the jury in understanding the
    evidence. See Commonwealth v. Rickbaugh, 
    706 A.2d 826
    , 837 (Pa.
    -9-
    J-A27024-16
    Super. 1997); Commonwealth v. Pelzer, 
    612 A.2d 407
    , 412 (Pa. 1992).
    An item may be used as a visual aid, even if not admitted into evidence, as
    long as the trial court concludes that it accurately reflects the testimony
    elicited as evidence during trial. See Commonwealth v. Twilley, 
    612 A.2d 1056
    , 1060 (Pa. Super. 1992) (citations omitted). Ultimately, permission to
    use visual aids during closing arguments “is within the sound discretion of
    the trial judge.” Pelzer, 
    612 A.2d at 412
    .
    Here, the trial court determined it was appropriate to allow Appellees’
    counsel to use both the tennis balls and Power Point presentation as visual
    aids during closing arguments because both items accurately reflected the
    trial testimony. See Trial Court Opinion, 6/30/15, at 11, 13. We agree.
    Appellant’s   own   expert   witness,   Dr.   Solomon,   testified    Appellant’s
    gynecomastia, caused by Risperdal usage, led to breast tissue the size of a
    tennis ball. See N.T., Trial, 3/3/15, Morning Session, at 44.        Further, our
    review of the Power Point presentation reveals that the content of each of
    the 75 slides accurately reflects the testimony elicited during the trial.
    Contrary to Appellant’s claims, Appellees’ counsel did not argue facts that
    were not in evidence—the slides were merely another iteration of the same
    proof that was presented orally.
    Additionally, as pointed out by Appellant in his first argument, the
    Power Point presentation itself is not evidence; it was merely a visual aid,
    used by Appellees’ counsel to assist the jury sort through the glut of
    - 10 -
    J-A27024-16
    testimony elicited during a month-long trial. Authentication of each slide was
    not required. See Pa.R.E. 901(a). See also Hon. Daniel J. Anders, Ohlbaum
    on the Pennsylvania Rules of Evidence, § 901.05 (2016 ed.) As both the
    tennis balls and Power Point presentation accurately reflected the evidence
    adduced at trial, it was within the discretion of the trial court to allow the
    display of both. We see no reason to disturb that discretion here.
    Finally, Appellant contends that even if the Power Point presentation
    was properly utilized during the closing argument, the trial court erred by
    denying his request to review Appellees’ Power Point presentation the day
    before closing arguments. See Appellant’s Brief, at 51. Appellant asserts
    that this ruling deprived him of the chance to prepare an effective rebuttal,
    and thus, denied him a fair trial. See id. However, Appellant can point to no
    rule requiring opposing counsel reveal materials from closing argument prior
    to trial. Moreover, as discussed at length above, the Power Point
    presentation was nothing more than a visual summation of the evidence
    adduced at trial. Appellant should have been prepared to dispute all
    evidence, favorable or unfavorable, presented during trial. Thus, this
    argument merits no relief.
    In his final two issues on appeal, Appellant challenges the trial court’s
    evidentiary rulings.
    When we review a ruling on the admission or exclusion of
    evidence, including the testimony of an expert witness, our
    standard is well-established and very narrow. These matters are
    within the sound discretion of the trial court, and we may
    - 11 -
    J-A27024-16
    reverse only upon a showing of abuse of discretion or error of
    law. An abuse of discretion may not be found merely because an
    appellate court might have reached a different conclusion, but
    requires a result of manifest unreasonableness, or partiality,
    prejudice, bias, or ill-will, or such lack of support so as to be
    clearly erroneous. In addition, to constitute reversible error, an
    evidentiary ruling must not only be erroneous, but also harmful
    or prejudicial to the complaining party.
    Freed v. Geisinger Medical Center, 
    910 A.2d 68
    , 72 (Pa. Super. 2006)
    (internal citations, brackets, and quotation marks omitted).
    Appellant contends the trial court erred by permitting Dr. Robb and Dr.
    Moltich, to testify that any chest examination of Appellant after he claimed
    to have developed breasts would have revealed tennis ball-sized breasts.
    See Appellant’s Brief, at 5, 39-47. In support of his contention of trial court
    error, Appellant offers two arguments. First, Appellant claims Dr. Robb and
    Dr. Moltich offered their opinion without the proper factual basis for their
    testimony. See id., at 42-44. Second, Appellant alleges this testimony
    should have been excluded as improperly exceeding the fair scope of Dr.
    Robb’s and Dr. Moltich’s pretrial expert reports. See id.
    Turning to the first argument, “expert testimony is incompetent if it
    lacks an adequate basis in fact.” Helpin v. Trustees of the University of
    Pennsylvania, 
    969 A.2d 601
    , 617 (Pa. Super. 2009) (citation omitted). This
    means that an expert’s testimony must be “based on more than mere
    personal belief,” and “must be supported by reference to facts, testimony or
    empirical data.” Snizavich v. Rohm & Haas, Co., 
    83 A.3d 191
    , 195 (Pa.
    Super. 2013) (citations omitted). While the facts supporting an expert
    - 12 -
    J-A27024-16
    opinion elicited at trial may be facts reasonably relied upon by experts in his
    particular field, an expert may also base his opinion on “[t]he facts or data
    in the case … that the expert has been made aware of or personally
    observed.” Pa.R.E. 703. In order to ensure that an expert’s opinion is
    properly supported, an expert must “state the facts or data on which the
    opinion is based.” Pa.R.E. 705. Examining counsel may ask the expert to
    assume the truth of testimony the expert has heard or read, or pose a
    hypothetical question to the expert. See 
    id.,
     Comment.
    This argument rests upon Appellant’s contention the record did not
    include sufficient evidence of the procedure surrounding his emergency room
    visit and chest examination for Appellees’ experts to offer testimony “as to
    whether, as a factual matter, [Appellant] ha[d] breasts in March 2013.”
    Appellant’s Brief, at 41-42. However, our review of the record reveals that
    Appellant misconstrues both the nature of the opinions offered by Dr. Robb
    and Dr. Moltich as well as the factual basis underlying their opinions.
    The testimony Appellant challenges was elicited through hypothetical
    questions posed by defense counsel as follows:
    [Defense Counsel]: Doctor, it has been suggested to the jury
    that [Appellant] had two tennis balls for breasts. Doctor, if you
    were performing a physical examination of a child, and let’s say
    that they had their shirt on or even a sweater, can you conceive
    of you not noticing two tennis balls on this young boy’s chest?
    [Appellant’s Counsel]: Objection for about six reasons.
    The court: Overruled.
    - 13 -
    J-A27024-16
    [Dr. Robb]: That would be impossible to miss, if they were the
    size of tennis balls, even with a sweatshirt on. And if I were
    examining the chest – when you think about it, all of you have
    had a physical examination and had the doctor listen to your
    heart, it’s on the left side of your chest. It would be impossible
    to miss a tennis ball as you’re listening to the four areas of the
    heart where you would listen on the left side of your chest.
    N.T., Trial, 3/9/15, Morning Session, at 54-55.
    [Defense Counsel]: Doctor, are you familiar with Dr. Solomon’s
    testimony about [Appellant’s] breast tissue?
    [Dr. Moltich]: I am.
    [Defense Counsel]: And, as an endocrinologist, would you expect
    that if a patient has tennis-ball sized breast tissue, it’s
    something that would be noticed and recorded by the examiner?
    [Dr. Moltich]: Oh, I certainly would.
    N.T., Trial, 3/10/15, Morning Session, at 66.
    Despite Appellant’s contention, neither of these expert opinions can be
    reasonably construed as factual testimony that Appellant did not have
    breasts as a result of gynecomastia when he was admitted to the emergency
    department in March 2013. Both doctors gave expert opinions based upon
    hypothetical situations posed to them by Appellees’ counsel. Further, these
    hypothetical questions were based upon facts of record. Appellant’s expert,
    Dr. Solomon, testified that Appellant had breasts the size of “tennis balls”
    and that a typical chest examination, such as the one performed on
    Appellant in the emergency department in March 2013, would likely miss the
    existence of these growths. Thus, we find this argument unavailing.
    - 14 -
    J-A27024-16
    Next, Appellant asserts the trial court should have excluded Dr. Robb’s
    and Dr. Moltich’s opinion testimony as exceeding the scope of their expert
    reports. See Appellant’s Brief, at 43-44. Specifically, Appellant claims both
    expert reports were limited to opinions concerning the validity of Appellant’s
    claim of Risperdal-induced gynecomastia. Thus, he argues any testimony
    regarding the ability to discover breast tissue during a chest examination
    exceeded the permissible scope. See 
    id.
    Pennsylvania Rules of Civil Procedure require that an expert’s
    testimony at trial be limited to the fair scope of his deposition
    testimony or pretrial report:
    To the extent that the facts known or opinion held by
    an expert have been developed in discovery
    proceedings under subdivision (a)(1) or (2) of this
    rule, the direct testimony of the expert at the trial
    may not be inconsistent with or go beyond the fair
    scope of his or her testimony in the discovery
    proceedings as set forth in the deposition, answer to
    an interrogatory, separate report, or supplement
    thereto ….

    ...
    [I]n deciding whether an expert’s trial testimony is
    within the fair scope of his report, the accent is on
    the word “fair.” The question to be answered is
    whether, under the circumstances of the case, the
    discrepancy between the expert’s pre-trial report and
    his trial testimony is of a nature which would prevent
    the adversary from preparing a meaningful response,
    or which would mislead the adversary as to the
    nature of the appropriate response.

    However, in situations where a plaintiff introduces certain evidence in
    his case in chief, he cannot later bar the opposition from disputing it. See
    Leaphart v. Whiting Corp., 
    564 A.2d 165
    , 171 (Pa. Super. 1989). “Thus,
    an expert's opinion offered in response to other testimony presented at trial
    need not be addressed in the expert's report.” Daddona v. Thind, 
    891 A.2d 786
    , 806 (Pa. Cmwlth. 2006) (citing Earlin v. Cravetz, 
    399 A.2d 783
     (Pa.
    Super. 1979)) (additional citation omitted).
    Here, while neither Dr. Robb nor Dr. Moltich opined about the ability of
    a medical provider to detect breast tissue in their expert reports, both of the
    contested opinions were offered directly in response to Dr. Solomon’s expert
    testimony that a typical chest examination would miss the existence of
    tennis ball-sized breasts. Thus, it did not need to be in their expert reports
    in order to be properly admitted. We have already determined that both Dr.
    Robb and Dr. Moltich’s testimony amounted to properly supported expert
    testimony. As such, Appellant’s third issue on appeal merits no relief.
    In his final issue on appeal, Appellant contests the trial court’s decision
    to allow Michelle Baker, a physician’s assistant who treated Appellant from
    2005 until 2013, to testify as to the cause of Appellant’s gynecomastia. See
    Appellant’s Brief, at 32-40. Appellant contends Baker’s testimony constituted
    improper expert testimony, as Baker was not qualified as an expert witness
    - 16 -
    J-A27024-16
    or designated as one pursuant to Pennsylvania Rule of Civil Procedure
    4003.5, prior to trial. See 
    id.
     Conversely, both the trial court and Appellees
    assert Baker’s testimony did not cross over into expert testimony, and as
    such, it was properly admitted as lay testimony of a fact witness. See Trial
    Court Opinion, at 6-8; Appellees’ Brief, at 14.
    Pennsylvania Rule of Evidence 701 provides:
    If a witness is not testifying as an expert, testimony in the form
    of an opinion is limited to one that is (a) rationally based on a
    witness’s perception; (b) helpful to clearly understanding the
    witness’s testimony or to determining a fact in issue; and (c) not
    based on scientific, technical, or other specialized knowledge
    within the scope of Rule 702.
    Pa.R.E. 701.
    Rule 702 mandates that
    [i]f scientific, technical or other specialized knowledge beyond
    that possessed by a layperson will assist the trier of fact to
    understand the evidence or determine a fact in issue, a witness
    qualified as an expert by knowledge, skill, expertise, training or
    education may testify thereto in the form of an opinion or
    otherwise.
    Pa.R.E. 702.
    Further, it is generally accepted that “[t]he cause and effect of a
    physical condition lies in a field of knowledge in which only a medical expert
    can give a competent opinion…. [Without experts] we feel that the jury could
    have no basis other than conjecture, surmise or speculation upon which to
    consider causation.” Toogood v. Owen J. Rogal, D.D.S., P.C., 
    824 A.2d 1140
    , 1149 (Pa. 2003) (citations omitted; brackets and ellipses in original).

    Here, Appellees do not dispute that they did not designate Baker as an
    expert or disclose any expert reports prior to trial. See Appellees’ Brief, at
    19. However, Appellees contend Baker’s testimony constituted permissible
    lay opinion testimony as it was rationally based on her perception of
    Appellant during treatment. See id., at 14. If Baker’s testimony only
    revealed this information, it would have been permissible lay witness
    testimony.
    However, during the taped deposition, Appellees elicited the following
    response from Baker:
    [Appellees’ Counsel]: And all of those weights we just reviewed
    were after Risperdal use had discontinued, correct?
    [Baker]: Yes, correct.
    [Appellees’ counsel]: [Baker], do you plan to offer any opinion
    as to – if indeed [Appellant] has chest growth, do you plan to
    offer any opinion as to the cause of that chest growth?
    [Baker]: The extreme weight gain, I would say.
    [Appellees’ counsel]: And what is the basis for that opinion?
    [Baker]: Because he hasn’t been on Risperdal since, we said,
    ’07, so if he was taken off the Risperdal, the prolactin [6] would
    have returned to normal.
    [Appellant’s counsel]: I’m going to enter an objection to this
    whole series of questions and answers.

    N.T., Trial, 2/25/15, Morning Session, at 20 (playing Baker Deposition
    recorded on 7/28/14) (emphasis added); Def. Ex. 19, Baker Deposition,
    7/28/14, at 101:5-101:21.
    Despite Appellees’ claims, in order to reach this conclusion, Baker was
    required to draw upon specialized medical knowledge concerning causation
    in order to opine that Appellant’s breast growth was caused by weight gain.
    The effect of Risperdal on a hormone such as prolactin is clearly a subject
    that requires specialized knowledge. This testimony clearly required the use
    of “scientific, technical, or other specialized knowledge within the scope of
    Rule 702.” Pa.R.E. 701. Thus, we conclude that the trial court erred in
    determining that Baker’s testimony did not constitute expert testimony.
    Appellees counter that even if Baker’s testimony constituted expert
    testimony, Baker, as a physician’s assistant, was qualified to testify as both
    an expert in causation and a fact witness. See Appellees’ Brief, at 14-16.
    The qualification of an expert witness rests with the sound discretion of
    the trial court. See Nobles v. Staples, Inc., 
    150 A.3d 110
    , 113 (Pa. Super.
    2016). “The standard for qualifying an expert witness is a liberal one; the
    witness need only have a reasonable pretension to specialized knowledge on
    a subject for which expert testimony is admissible.” Commonwealth v.
    Kinard, 
    95 A.3d 279
    , 288 (Pa. Super. 2014) (en banc) (citation omitted). A
    - 19 -
    J-A27024-16
    witness who is not a medical doctor may be qualified as an expert witness
    regarding medical issues. See Miller v. Brass Rail Tavern, Inc., 
    664 A.2d 525
    , 528-529 (Pa. 1995).
    This Court has recognized that the rules governing expert and lay
    testimony do not preclude a single witness from testifying as both a lay
    witness and an expert witness in the same trial. See Commonwealth v.
    Huggins, 
    68 A.3d 962
    , 967 (Pa. Super. 2013).
    The witness’ association to the evidence controls the scope of
    admissible evidence that he or she may offer. In order to avoid
    jury confusion, the trial court should direct the [proffering party]
    to clarify when testimony, given in the form of an opinion, was
    based upon expert knowledge, as opposed to testimony
    regarding the facts as personally perceived…. [S]hould a single
    witness testify in dual capacities, the trial court must instruct the
    jurors regarding lay versus expert testimony and tell them that
    they are solely responsible for making credibility determinations.
    Commonwealth v. Yocolano, 
    169 A.3d 47
    , 62 (Pa. Super. 2017) (some
    brackets added and omitted; quotation marks and citations omitted).
    We recognize that Baker, as a licensed physician’s assistant, had
    qualifications that could have met the standard for an expert witness.
    However, because the trial court believed Baker’s testimony did not amount
    to expert testimony, the trial court failed to determine if Baker was qualified
    as an expert witness. Further, the trial court, believing Baker’s testimony to
    be fact testimony, did not ensure that the jury was able to separate Baker’s
    expert testimony from her lay testimony. See 
    id.
     As such, we find the trial
    - 20 -
    J-A27024-16
    court abused its discretion and erred as a matter of law in permitting a lay
    witness to offer an expert opinion at trial.
    Appellant argues that the effect of this erroneous ruling deprived him
    of a fair trial and that he should be granted a new trial on the issues of
    causation and damages. See Appellant’s Brief, at 58. We are constrained to
    agree.
    Throughout the entire trial, the parties relied on the opinions of
    experts as to the cause of Appellant’s gynecomastia. Appellant’s experts
    opined that Appellant’s gynecomastia occurred before 2013 and was caused
    by Risperdal ingestion. Appellees’ experts opined that weight gain rather
    than Risperdal ingestion caused Appellant to appear to have gynecomastia.
    Baker’s testimony, in which she opined that Appellant’s weight gain, rather
    than his Risperdal usage, caused him to appear to have gynecomastia, was
    the only causation testimony offered by a witness who personally treated
    Appellant.
    This opinion was offered without the proper vetting and safeguards
    surrounding expert testimony. Further, this opinion was introduced into
    evidence due to the trial court’s improper application of the law, which is
    clearly an abuse of discretion. Therefore, we find that the trial court abused
    its discretion in denying Appellant’s request for a new trial, limited to the
    issues of causation and damages.
    Judgment reversed. Case remanded for further proceedings consistent
    with this opinion. Jurisdiction relinquished.
