How has the court treated questions about the depth or scope of expert testimony in a medical malpractice case?

There being sufficient evidence to conclude the trial court did not abuse its broad discretion in finding Donnelly's testimony was not outside of her expertise within the meaning of Evidence Code section 720, questions about the depth or scope of her knowledge or experience go to the weight, not the admissibility, of her testimony. (People v. Eubanks, supra, 53 Cal.4th at p. 140.)
