What is the relevance of evidence in a medical malpractice case?

I believe there is a substantial probative value that substantially outweighs any potential prejudice particularly when any potential prejudice from the court's perspective can be mitigated by [defense counsel's] questioning concerning the very specific natures and durations of the drugs and narcotics used." We review the trial court's determination regarding the relevance of evidence and whether its prejudicial effect outweighs its probative value for an abuse of discretion. ( People v. Horning (2004) 34 Cal.4th 871, 900, 22 Cal.Rptr.3d 305, 102 P.3d 228.)
