    Submitted May 25, 2017 – Decided July 25, 2017
    Before Judges Hoffman, O'Connor and Mawla.
    On appeal from Superior Court of New Jersey,
    Law Division, Camden County, Docket No. L-
    2859-13.

    brief).
    The opinion of the court was delivered by
    HOFFMAN, J.A.D.
    Plaintiff Norma S. Ehrlich appeals from a January 28, 2016
    Law Division order dismissing her complaint against defendant
    Jeffrey J. Sorokin, M.D., based on a no-cause jury verdict in
    her medical negligence action.     This suit arose after plaintiff
    suffered     complications         from    a     colonoscopy        and     polypectomy
    procedure defendant performed in 2011.                       On appeal, plaintiff
    raises three claims of trial error, asserting the judge (1)
    admitted    irrelevant      evidence       regarding       informed       consent,      (2)
    delivered inadequate jury instructions on the standard of care,
    and (3) admitted net opinion testimony.                    Following our review of
    the   record      and   applicable        law,   we    agree       the    admission      of
    informed consent evidence constituted harmful error.                        R. 2:10-2.
    We therefore vacate the order of dismissal and remand for a new
    trial consistent with this opinion.
    I.
    We begin by summarizing the most pertinent evidence from
    the record.        In May 2003, plaintiff first came under the care of
    defendant,     a    gastroenterologist,          after      her    family       physician
    referred    her     based   upon    complaints        of    back    pain    and    rectal
    bleeding.            Defendant      recommended            plaintiff       undergo         a
    colonoscopy, which he performed on May 27, 2003.
    Plaintiff's colonoscopy revealed the presence of a polyp at
    the tip of her cecum opposite the ileocecal valve.                         According to
    defendant, because the polyp's size and histologic type made it
    a   significant      risk   for    malignancy,        he    recommended         plaintiff
    undergo surgery to remove a portion of her colon.                               Plaintiff
    declined     surgery,       so     defendant      referred         her     to     another
    2                                     A-2781-15T3
    gastroenterologist, Dr. Jerome Waye, one of the few doctors who
    — at that time — removed polyps with a colonoscope.
    On November 14, 2003, Dr. Waye performed this procedure;
    however, plaintiff subsequently suffered a hemorrhage.             In May
    2004, plaintiff returned to the care of defendant, who informed
    her she needed a surveillance colonoscopy.            Because plaintiff
    suffered    from    recurrent   polyps,   defendant    performed     five
    colonoscopy and polypectomy procedures between 2004 and 2011.
    Defendant    used    several    techniques   to   remove    plaintiff's
    recurrent polyps.      One of these procedures, the "saline lift"
    technique, involves injecting fluid into the colon to lift the
    polyp from the colon wall.        Once lifted, the polyp is usually
    removed with a hot or cold snare.
    An alternative procedure, Argon Plasma Coagulation (APC),
    utilizes a thin catheter passed through a channel.           Conductive
    argon gas then passes through the channel to the location of the
    polyp, followed by an electrical charge that vaporizes the cells
    of the polyp.      Unlike the snare technique, the APC catheter does
    not make direct contact with the polyp.
    Defendant applied the following techniques to remove polyps
    from plaintiff's colon on the following dates:
    November 16, 2004 - saline lift to remove a
    polyp with a hot snare.
    3                          A-2781-15T3
    December 28, 2005 - saline lift to remove a
    polyp with hot and cold snares.
    March 20, 2007 - hot snare to remove a
    polyp; at trial, defendant explained he did
    not   use  saline  because   his   "clinical
    judgment was that it did not need the
    saline."
    September 21, 2009 – hot snare to remove a
    polyp, followed by the APC to "ablate
    whatever remaining polyp tissue was there."
    August 29, 2011 – APC to remove a polyp.
    Following     the       August       29   procedure,         defendant    discharged
    plaintiff to her home; however, at approximately 3:00 a.m. on
    August 30, plaintiff awoke in pain and told her husband, "[C]all
    9-1-1[,]    I'm   in     trouble."             Emergency         personnel    transported
    plaintiff    to   Virtua       Hospital,           where    she    underwent    emergency
    surgery.     Virtua doctors determined plaintiff suffered from a
    perforation of her colon and peritonitis.                         The doctors performed
    a   right    hemicolectomy,           ileostomy,           and     mucous     fistula     on
    plaintiff.        She        later    underwent            surgery    to     reverse    the
    ileostomy.
    Plaintiff filed her complaint against defendant on July 12,
    2013,   alleging        he     negligently           performed       the     August     2011
    procedure    by   "[f]ailing         to    inject      the    polyp    and    surrounding
    colon with Saline to create a cushion underneath the polyp."
    She did not assert a claim for lack of informed consent.
    4                                  A-2781-15T3
    The case proceeded to a jury trial in January 2016.                          Prior
    to   testimony,     plaintiff    moved    in       limine    to   exclude    evidence
    regarding her consent to the colonoscopy procedures from 2003 to
    2011.   The trial judge denied the motion, finding "the forms and
    any information provided to the patient was part of the standard
    of care, and therefore relevant."                  Plaintiff again raised the
    issue after opening statements, but the judge reaffirmed his
    decision.
    Plaintiff      then     testified,       describing         her    history       of
    treatment   with     defendant.       Because         the    trial      court    denied
    plaintiff's    in     limine     motion       to    exclude       informed      consent
    evidence,     plaintiff's        counsel        also        questioned       plaintiff
    regarding   the     various     consent       forms    she    signed     before     each
    procedure completed by defendant.1
    On cross-examination, defense counsel asked plaintiff about
    the language from one of her consent forms, which stated the
    procedure could result in injury and hospitalization.                        Plaintiff
    said the form indicated "passage of the instrument may result in
    an injury, but it never said that there would be a possibility
    1
    During the charge conference following the conclusion of
    testimony, plaintiff's counsel explained that he addressed
    informed consent matters during his case in chief only after the
    trial court rejected his request to exclude informed consent
    evidence as irrelevant.
    5                                     A-2781-15T3
    that my colon might be burnt."                     Defendant also asked plaintiff
    about the 2011 consent form, which she signed in defendant's
    office       in   June     2011,    two        months      before        the    August        2011
    procedure.        Plaintiff reiterated defendant never discussed the
    potential for burning.
    Plaintiff            presented               expert          testimony                 from
    gastroenterologist Stuart Finkel, M.D., who asserted defendant
    deviated from the standard of care in both the 2009 and 2011
    procedures.       Regarding the 2011 procedure, Dr. Finkel stated the
    APC    burned     plaintiff's       colon,         resulting       in    the    perforation,
    because       defendant     "failed       to    perform       saline       injection          lift
    technique prior to that application of the APC, which increased
    her risk for this particular complication."                             He noted "that the
    finding of a flat, broad, [two] centimeter sessile polyp in . .
    .     the    thinnest     area     of   the        colon     and    most       at    risk        for
    perforations"          required    defendant         to    "create        [a]       cushion       of
    saline"       before     using    the   APC;       defendant's          failure      to     do   so
    deviated from the standard of care.
    Defendant presented expert testimony from Timothy Hoops,
    M.D.        Prior to Dr. Hoops' testimony, the judge held an N.J.R.E.
    104 hearing to determine the admissibility of his opinion on
    proximate cause.           According to Dr. Hoops, plaintiff's multiple
    polypectomies likely would have scarred her tissue or resulted
    6                                          A-2781-15T3
    in     fibrosis,   which    would       make    the   saline     lift      procedure
    ineffective by holding down the surface of the tissue.                      He gave
    his opinion to a reasonable degree of medical probability, based
    on "years of both my experience, as well as experience of people
    that I've seen . . . and on the medical literature."                        However,
    Dr. Hoops conceded none of defendant's records for plaintiff
    mentioned      scarring    or   fibrosis.         Plaintiff      thus      moved    to
    preclude this testimony as net opinion, which the trial judge
    denied.     Dr. Hoops then testified to this information before the
    jury.
    Dr. Hoops also testified that defendant's use of the APC
    "was within the accepted standards of care."                  He noted, "At the
    time    [the    2011]     procedure      was    performed,"      there     were     no
    guidelines     regarding     the    use    of   saline   with        the   APC,     and
    "[t]here was nothing for it or against it;" in addition, he had
    never seen a doctor use them together.                He further noted, "[A]t
    the time of the procedure . . . there was no evidence that doing
    the saline lift would have reduced the risk for perforation."
    On cross-examination, Dr. Hoops acknowledged that saline lifts
    are "very safe" overall, but added, "[T]here might be some risks
    for infection."
    Defendant    testified      he     did   not   use      the    saline       lift
    technique during the August 2011 procedure because "there was no
    7                                 A-2781-15T3
    literature to support the use of the saline lift technique with
    an [APC]."       He said there is a risk for perforation any time he
    performs     a   colposcopy,      and     burning        a    colon     is   a    "known
    complication of the use of [the APC] for the performance of
    colonoscopy."
    At the end of the testimony, the trial judge allowed the
    jury to review plaintiff's informed consent documents as part of
    its   deliberation.       Responding          to   plaintiff's        objection,       the
    judge stated:
    If you can go and talk about all that Dr.
    Sorokin had done in 2003, 2004, 2005 and so
    on, and exclude this small piece of it, that
    cannot be consistent with notions of justice
    or the search of truth. And maybe if I mis-
    characterized it as going to the standard of
    care that was my fault and a mistake.    But
    in a fundamental sense, there could be no
    way to have a fair trial that would allow
    the plaintiff to explore this treatment for
    all these years, include the detail of it,
    including almost every single statement
    written by Dr. Sorokin, and exclude the
    informed consent.   That can't be consistent
    with a notion of a fair trial.
    Plaintiff then submitted a proposed jury instruction on the
    standard   of    care.    The     trial       judge   denied      this   request       and
    proceeded to charge the jury under the model jury charge.                              The
    next day, the jury asked the court to reiterate "the definition
    of standard of care[.]"          Plaintiff again requested a custom jury
    charge,    but     the   judge     re-read         the       previous    instruction.
    8                                      A-2781-15T3
    Following       additional       deliberation,     the    jury     reached     a     6-1
    verdict that defendant did not breach the standard of care.
    Plaintiff filed a motion for a new trial, which the judge
    denied.    This appeal followed.
    II.
    We     first    address      plaintiff's      contention     the   trial       judge
    erred by allowing defendant to present irrelevant and misleading
    evidence of her informed consent to the colonoscopy procedures.
    Plaintiff argues, because she did not assert a claim for lack of
    informed    consent,       the     sole   issue   was    whether    defendant       was
    negligent for failing to perform a saline lift with the APC.
    She asserts a new trial is necessary because defendant misled
    the jury to believe consent was connected to the standard of
    care.     We are constrained to agree.
    Our     review    of     the    trial    court's    evidential     rulings      "is
    limited    to    examining       the   decision   for    abuse   of    discretion."
    Parker v. Poole, 
    440 N.J. Super. 7
    , 16 (App. Div.) (quoting
    Hisenaj v. Kuehner, 
    194 N.J. 6
    , 12 (2008)), certif. denied, 
    223 N.J. 163
    (2015).       We will only reverse if the error "is of such
    a nature as to have been clearly capable of producing an unjust
    result."    
    Ibid. (quoting R. 2:10-2).
    Pursuant to our rules, evidence is relevant if it has "a
    tendency in reason to prove or disprove any fact of consequence
    9                               A-2781-15T3
    to the determination of the action."                    N.J.R.E. 401.          Relevant
    evidence     is    generally      admissible,       N.J.R.E.      402,   but   "may    be
    excluded if its probative value is substantially outweighed by
    the risk of . . . undue prejudice, confusion of issues, or
    misleading the jury."          N.J.R.E. 403.
    To prevail in a medical malpractice action based upon a
    deviation     from     the    standard         of   care,   the     plaintiff     "must
    generally      present       expert      testimony      establishing       '(1)       the
    applicable standard of care; (2) a deviation from that standard
    of   care;    and    (3)   that    the    deviation     proximately       caused      the
    injury.'"         Newmark-Shortino v. Buna, 
    427 N.J. Super. 285
    , 304
    (App. Div. 2012) (quoting Telihaber v. Greene, 
    320 N.J. Super. 453
    , 465 (App. Div. 1999)), certif. denied, 
    213 N.J. 45
    (2013).
    "A physician must act with that degree of care, knowledge, and
    skill ordinarily possessed and exercised in similar situations
    by   the   average     member      of    the    profession     practicing       in    the
    field."      Aiello v. Muhlenberg Reg'l Med. Ctr., 
    159 N.J. 618
    , 626
    (1999).
    Informed consent is generally unrelated to the standard of
    care for performing medical treatment.                      Eagel v. Newman, 
    325 N.J. Super. 467
    , 474-75 (App. Div. 1999).
    [T]he informed-consent basis of malpractice,
    as opposed to deviation from the applicable
    standard of care, rests not upon the
    physician having erred in diagnosis or
    10                                  A-2781-15T3
    administration of treatment but rather in
    the failure to have provided the patient
    with adequate information regarding the
    risks of a given treatment or with adequate
    information regarding the availability of
    alternative treatments and the comparative
    risks and benefits of each.
    [Ibid.]
    "Although       each      cause   of          action    is    based      on    different
    theoretical underpinnings, 'it is now clear that deviation from
    the standard of care and failure to obtain informed consent are
    simply   sub-groups         of    a   broad          claim    of    medical     negligence.'"

    However,       these       theories      are          distinguishable         because        they
    represent two independent duties: "(1) the duty to diagnose and
    treat a patient in accordance with the standard of care; and (2)
    the    duty     to     disclose        all       medically          reasonable        treatment
    alternatives      .    .    .    so   that       a    patient      may   make    an    informed
    decision."

    Plaintiffs        must     meet       a       different,       four-part       test     to
    establish the prima facie case for lack of informed consent.
    See 
    Telihaber, supra

    claim based on lack of informed consent, the patient must prove
    that     the     doctor         withheld         pertinent          medical       information

    As   plaintiff          recognizes,       there    are       no    New    Jersey       cases
    specifically addressing the admissibility of informed consent
    evidence    where     the       plaintiff       has     only       asserted      a    claim      of
    negligent treatment.             She therefore relies on cases from other
    state    courts     addressing         this     issue,    in        particular        a    recent
    Pennsylvania Supreme Court decision, Brady v. Urbas, 
    111 A.3d 1155
    (Pa. 2015).
    In   Brady,    the       plaintiff      asserted         a    claim      for    negligent
    treatment and moved in limine to exclude any consent-related
    evidence; the trial court denied her motion.                                  After reviewing
    the evidence during deliberations, the jury returned a verdict
    in favor of the plaintiff's doctor.                      
    Id. at 1158.
                   On appeal,
    the doctor argued the evidence was relevant to establish the
    applicable standard of care.                    
    Id. at 1159.
                    The Pennsylvania
    Supreme Court disagreed, finding "the fact that a patient may
    have agreed to a procedure in light of the known risks does not
    make it more or less probable that the physician was negligent
    in either considering the patient an appropriate candidate for
    the     operation        or    in     performing         it        in    the     post-consent
    timeframe."       
    Id. at 1162.
               The Court also concluded that such
    12                                          A-2781-15T3
    evidence could confuse the jury by distracting it from whether
    the doctor breached the standard of care.                   
    Id. at 1163-64.
    The     other    state   courts      plaintiff          cites    reached      similar
    conclusions.        See Baird v. Owczarek, 
    93 A.3d 1222
    , 1232 (Del.
    2014)   (agreeing     that   "evidence        of    informed        consent,      such   as
    consent    forms,    is   both    irrelevant        and     unduly    prejudicial        in
    medical malpractice cases without claims of lack of informed
    consent"    (quoting      Hayes    v.   Camel,      
    927 A.2d 880
    ,    889    (Conn.
    2007))); Waller v. Aggarwal, 
    688 N.E.2d 274
    , 275 (Ohio Ct. App.
    1996) ("[T]he issue of informed consent was not relevant to
    appellant's claim of negligence."); Wright v. Kaye, 
    593 S.E.2d 307
    , 317 (Va. 2004) (holding where the plaintiff did not plead
    lack of informed consent, "evidence of information conveyed to
    [plaintiff] concerning the risks of surgery in obtaining her
    consent is neither relevant nor material to the issue of the
    standard    of   care");     cf.    
    Hayes, supra
    ,    927     A.2d    at     889-91
    (holding the trial court abused its discretion by admitting such
    evidence, but finding the error harmless).
    Additional       state   courts     have       found     evidence       of   informed
    consent irrelevant and potentially prejudicial where the issue
    was negligent treatment.           See Schwartz v. Johnson, 
    49 A.3d 359
    (Md. Ct. Spec. App. 2012); Wilson v. Patel, 
    517 S.W.3d 520
    (Mo.
    2017); Warren v. Imperia, 
    287 P.3d 1128
    (Or. Ct. App. 2012); cf.
    13                                       A-2781-15T3
    Liscio v. Pinson, 
    83 P.3d 1149
    , 1156 (Colo. App. 2003) (finding
    informed consent evidence may be irrelevant but not reversible
    error where the plaintiff "opened the door").
    Furthermore, although not directly on point, our decision
    in Gonzalez v. Silver, 
    407 N.J. Super. 576
    (App. Div. 2009), is
    instructive on this issue.               Gonzalez was a medical malpractice
    action   wherein    the     defendant          doctor       attempted      to    introduce
    hearsay testimony regarding statements plaintiff made about the
    cause of his injury.         
    Id. at 593.
                 We held that such testimony
    was irrelevant to the issue of whether or not the defendant
    doctor provided proper medical care, and though it was perhaps
    relevant for impeachment, it carried "an enormous potential for
    prejudice."     
    Id. at 594-95.
               We concluded the balance "should
    have weighed in favor of excluding such evidence."                         
    Id. at 595.
    Considering         Gonzalez    and       the     non-binding       but     persuasive
    out-of-state    cases,      we     are    convinced          the     admission     of   the
    informed     consent     evidence        in        this    matter,    where      plaintiff
    asserted     only   a    claim     of     negligent          treatment,       constituted
    reversible     error.       The     only           issue    at     trial   was    whether
    defendant's use of the APC without a saline lift deviated from
    the standard of care.            Plaintiff's acknowledgment of the risk
    for perforation had no bearing on this determination.                              Indeed,
    although negligent treatment and informed consent fall under the
    14                                  A-2781-15T3
    umbrella of medical negligence, our law clearly distinguishes
    the two claims, and they require different elements of proof.
    See    
    Newmark-Shortino, supra
    ,      427    N.J.    Super.    at       304.        We
    therefore conclude the informed consent evidence was irrelevant
    to the issue presented at trial, N.J.R.E. 401, and should have
    been excluded on plaintiff's motion in limine.
    We reject defendant's assertion the evidence was relevant
    to    "counter    plaintiff's       testimony     on    direct    examination         that
    [defendant] gave plaintiff absolutely no information about her
    condition and treatment."              We also disagree with the judge's
    end-of-trial       conclusion       that    plaintiff       opened      the    door       by
    exploring her entire history with defendant.                     Rather, the record
    shows    that    after    twice     attempting     to     exclude    this     evidence,
    plaintiff       tried    to   minimize     its    damage    by   addressing          it   on
    direct examination.           As the judge incorrectly ruled the informed
    consent evidence admissible prior to any testimony, we flatly
    reject defendant's attempt to assign relevance to this evidence
    after the fact.           Moreover, we find defendant went beyond the
    purported purpose of rebutting plaintiff's claims by raising the
    consent issue during Dr. Hoops' testimony and during summation.
    We   further      conclude    this    evidence      had    the     capacity        to
    mislead the jury, N.J.R.E. 403, thereby making it capable of
    producing an unjust result.                R. 2:10-2.        As the Pennsylvania
    15                                   A-2781-15T3
    Supreme Court noted, "the jury might reason that the patient's
    consent    to    the    procedure   implies    consent     to    the   resultant
    injury, see Wright, 
    [supra,] 593 S.E.2d at 317
    , and thereby lose
    sight     of    the    central   question     pertaining    to    whether     the
    defendant's      actions    conformed    to   the    governing     standard    of
    care."     
    Brady, supra
    , 111 A.3d at 1163.               This was especially
    true here, where the jury received the consent forms as part of
    their deliberations, immediately after hearing defense counsel's
    summation referencing this issue.
    Accordingly, we conclude that the admission of the informed
    consent    evidence     constituted     reversible   error.       We   therefore
    vacate the dismissal order and remand for a new trial.
    III.
    In order to provide guidance to the court on remand, we
    briefly address plaintiff's remaining arguments and find they
    lack merit.        Plaintiff first argues the trial judge erred by
    rejecting her proposed jury charge on the standard of care.                   The
    proposed charge added the following language to the model jury
    charge:
    The law recognizes that the practice of
    medicine   is     not    an    exact science.
    Therefore,    the     practice    of medicine
    according to accepted medical standards may
    not prevent a poor or unanticipated result.
    However, when a risk is obvious, and a
    precautionary measure available, an industry
    or professional standard that does not call
    16                              A-2781-15T3
    for such precaution is not conclusive if,
    regardless of the standard or custom, the
    exercise of reasonable care would call for a
    higher standard.     Therefore, whether Dr.
    Sorokin was negligent depends not on the
    outcome but on whether he adhered to or
    departed from the applicable standard of
    care.
    [(emphasis added).]
    Plaintiff based this language on our decision in Estate of
    Elkerson v. North Jersey Blood Center, 
    342 N.J. Super. 219
    (App.
    Div.), certif. denied, 
    170 N.J. 390
    (2001).                  In Elkerson, the
    plaintiff produced expert testimony establishing that the entire
    blood bank industry was following inadequate safety standards in
    screening    donated      blood,   when      a   better   test   was   known   and
    available.       
    Id. at 233-35.
           In that context, we held the trial
    court erred in limiting the jury to considering whether the
    defendant blood bank followed the prevailing industry practice
    at the time of the plaintiff's blood transfusion.                  "[T]he trial
    court's negligence charge constitutes reversible error because
    it   did   not   allow    the   jury    to   reject   the   industry    standard
    applied uniformly by blood banks in 1983 in favor of its own
    expert-informed judgment in determining whether that custom was
    or was not reasonable."         
    Id. at 235.
    Elkerson     is    inapplicable     here    because   plaintiff    did   not
    produce an expert report to opine the existing standard of care
    for APC use was unreasonable.                Rather, this was a case where
    17                               A-2781-15T3
    plaintiff presented expert testimony that the standard of care
    required defendant to use the saline lift with the APC, and
    defendant presented expert testimony that the standard of care
    did not require this technique.            Unlike in Elkerson, here no
    guidelines stated doctors should not use a saline lift with the
    APC.     We therefore find the trial judge did not err by rejecting
    plaintiff's requested charge.
    Plaintiff also argues the trial judge erred by permitting
    Dr. Hoops to deliver net opinion testimony regarding proximate
    cause.     "The net opinion rule is a 'corollary of [N.J.R.E. 703]
    . . . which forbids the admission into evidence of an expert's
    conclusions that are not supported by factual evidence or other
    data.'"        Townsend   v.   Pierre,     
    221 N.J. 36
    ,   53-54    (2015)
    (alterations in original) (quoting Polzo v. County of Essex, 
    196 N.J. 569
    , 583 (2008)).         A net opinion is "a bare conclusion
    unsupported by factual evidence."           Creanga v. Jardal, 
    185 N.J. 345
    , 360 (2005).       To avoid a net opinion, the expert must "'give
    the why and wherefore' that supports the opinion."                 
    Townsend, supra
    , 221 N.J. at 54 (quoting Borough of Saddle River v. 66 E.
    Allendale, LLC, 
    216 N.J. 115
    , 144 (2013)).
    Experts are required to "be able to identify the factual
    bases    for   their   conclusions,   explain    their    methodology,       and
    demonstrate that both the factual bases and the methodology are
    18                               A-2781-15T3
    reliable."       
    Id. at 55
    (quoting Landrigan v. Celotex Corp., 
    127 N.J. 404
    , 417 (1992)).           The net opinion rule is a "prohibition
    against speculative testimony."            Harte v. Hand, 
    433 N.J. Super. 457
    , 465 (App. Div. 2013) (quoting Grzanka v. Pfeifer, 301 N.J.
    Super. 563, 580 (App. Div. 1997), certif. denied, 
    154 N.J. 607
    (1998)).
    Dr. Hoops testified that plaintiff's multiple polypectomies
    would    have    caused   scarring   in    her    colon,    likely   making   the
    saline lift procedure ineffective.                Plaintiff asserts, because
    defendant's notes contained no reference to scar tissue, Dr.
    Hoops' testimony on this issue "constituted nothing more than
    mere speculation."        Although the record did not show definitive
    evidence of scarring, Dr. Hoops set forth the factual basis for
    his opinion, noting in the "majority of cases," a polypectomy
    procedure would result in scarring, and it was "[a]bsolutely
    more likely than not that . . . [the] area would have been
    scarred down and would not have lifted.               The . . . saline lift
    would have been unsuccessful; you would have had a non-lift
    sign."      He    based   this    opinion    on    his     medical   experience.
    Therefore, giving deference to the trial judge's decision on
    expert testimony, 
    Townsend, supra
    , 221 N.J. at 52, we discern no
    error in his admission of this evidence.
    Vacated and remanded.          We do not retain jurisdiction.
