OPINION
{1 In this medical malpractice action, Plaintiffs Steven and Stacey Woods appeal a jury verdict finding that Defendant Gary R. Zeluff, M.D., did not breach the applicable standard of care in conjunction with an operation on Steven's toe. Plaintiffs argue that the trial court erred by excluding, as unfairly prejudicial, post-operative statements allegedly made by Dr. Zeluff and that such error warrants a new trial. We agree.
BACKGROUND
12 Steven Woods was experiencing toe pain and sought treatment from Dr. Zeluff. Without offering more conservative treat *554 ments for the pain or referring Steven to a rheumatologist, Dr. Zeluff determined that Steven was a good candidate for MTP-implant surgery. 1 The surgery was unsuccessful, however, requiring additional corrective surgeries and ultimately rendering Steven permanently disabled.
I 3 During a post-operative visit, Dr. Zeluff allegedly told Steven, "I jumped the gun," "I've missed something," and "I don't think we should have done this surgery." Plaintiffs subsequently filed a medical malpractice action against Dr. Zeluff and related entities.
T4 Defendants filed a motion in limine requesting that testimony regarding Dr. Ze-Iuffs alleged post-operative statements be excluded at trial. After a hearing on the matter, the trial court granted the motion, refusing to allow the use of such testimony "on the grounds that the testimony is minimally probative and is substantially outweighed by the dangers of unfair prejudice." The case proceeded to trial, and the jury found in favor of Defendants. Plaintiffs now appeal.
ISSUE AND STANDARD OF REVIEW
T5 Plaintiffs argue that the trial court erred in applying the evidentiary balancing test of rule 408 of the Utah Rules of Evidence. See Utah R. Evid. 403 of the Utah Rules of Evidence. "In reviewing a trial court's ruling on the admissibility of evidence under rule 408, we will not overturn the court's determination unless it was an abuse of discretion." State v. Hamilton,
ANALYSIS
T6 Under the Utah Rules of Evidence, relevant evidence is generally admissible. See Utah R. Evid. 402. Relevant evidence is defined as "evidence having any tendency to make the existence of any fact that is of consequence to the determination of the action more probable or less probable than it would be without the evidence." Id. 401. Under this broad definition, the trial court determined that the statements allegedly made by Dr. Zeluff that he "missed something," "jumped the gun," and "shouldn't have done this surgery" were relevant to the question of Dr. Zeluffs negligence. Under rule 408, however, even relevant evidence "may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice." Id. 403. It is the result of this balancing test that the parties dispute on appeal.
17 We agree with Plaintiffs that testimony regarding Dr. Zeluffs statements should not be excluded under rule 403 because the testimony is not unfairly prejudicial. In its determination below, the trial court made several references to the evidence as being "highly prejudicial." Indeed it is. But prejudice alone is not sufficient justification to exclude the evidence. Rather, the balancing test under rule 408 requires measuring the danger of unfair prejudice.
Since all effective evidence is prejudicial in the sense of being damaging to the party against whom it is offered, prejudice which calls for exclusion is given a more specialized meaning: an undue tendency to suggest decision on an improper basis, commonly but not necessarily an emotional one, such as bias, sympathy, hatred, contempt, retribution or horror.
State v. Maurer,
T8 Even recognizing this minimal risk of unfair prejudiee-for example, the jury might conceivably confuse the doctor's subjective sense of his personal standard of care with the standard of care ordinarily exercised by doctors in similar situations-we readily conclude that exclusion would be improper. "The mere fact that evidence possesses a tendency to suggest a decision upon an improper basis does not require exclusion; evidence may be excluded only if the danger of unfair prejudice substantially outweighs the probative value of the proffered evidence." Id. (internal quotation marks and citation omitted) (emphasis added). See Utah R. Evid. 403; K-B Trucking Co. v. Riss Int'l Corp.,
19 Defendants argue that the statements had very little probative value because they were, at most, words of compassion or remorse, and that they would be insufficient to establish that Dr. Zeluff's conduct fell below the standard of care. But Defendants do not point to, nor do we find, any case in which testimony of similar statements by a treating physician was completely withheld from the fact finder. Instead, the cases Defendants discuss in support of their argument only *556 establish that Dr. Zeluff's statements may not alone be sufficient to establish negligence. 5 Even assuming Defendants are correct in their assertion that Dr. Zeluff's statements, alone, are insufficient to support a finding of medical negligence, the statements are nonetheless clearly probative, see Black's Law Dictionary 579 (ith ed.1999) (defining "probative evidence" as "[elvidence that tends to prove or disprove a point in issue") {emphasis added), and Defendants' assertion does not alter our rule 403 analysis.
110 Finally, we determine that the trial court's error in exeluding testimony regarding Dr. Zeluffs statements was prejudicial to Plaintiffs. Statements by the treating doctor that he "missed something," "jumped the gun," and "shouldn't have done this surgery" tend to reflect a medical expert's assessment of his own care-an assessment which would likely carry considerably more weight than that of medical experts not involved in the patient's treatment. Thus, testimony regarding these alleged statements, if believed, would be central to Plaintiffs' case, and we conclude that absent the erroneous exclusion, "there is a reasonable likelihood of an outcome more favorable to [Plaintiffs]." State v. Dunn,
CONCLUSION
111 Testimony regarding the statements allegedly made by Dr. Zeluff was not unfairly prejudicial to such a degree as to substantially outweigh its probative value. Exelusion of such testimony was therefore in error, and this error was prejudicial to Pldintiffs. Accordingly, we reverse and remand for a new trials. 6

Notes
. MTP is an acronym for metatarsophalangeal joints, which are basically the joints connecting the toes to the feet. Webster's Medical Desk Dictionary 430 (1986).
. Several cases to which we refer are federal cases discussing rule 403 of the Federal Rules of Evidence. This federal rule is identical to the Utah rule, compare Fed.R.Evid. 403, with Utah R. Evid. 403, and such reference is therefore appropriate. See State v. Fedorowicz,
. Defendants argue that Dr. Zeluff®'s statements "could not reflect Dr. Zeluff's personal opinions or impressions because he strongly contests ever making the statements." This argument is misplaced. The question of whether Dr. Zeluff actually made the statements calls for a routine credibility determination, which is completely within the province of the jury, and a simple assertion that the statements were never made does not tip the rule 403 balancing test in favor of exclusion. See State v. Branch,
. Moreover, an appropriate cautionary instruction would be effective in reducing or eliminating the danger of confusion here. See Fed.R.Evid. 403 advisory committee note ("[CJonsideration should be given to the probable effectiveness or lack of effectiveness of a limiting instruction.").
. The primary cases discussed by Defendants are Sutton v. Calhoun,
. Given our determination of the evidentiary issue and the resulting remand, we need not address Defendants' argument regarding juror bias, since any error in that regard will also be remedied by our remand and the impaneling of a new jury.
