How has the court treated the testimony of a forensic expert in a medical malpractice case?

The doctor was testifying within his special knowledge of forensic medicine and his conclusions were properly based on facts assumed from the evidence (Evid.Code, 801). The subject was one not equally within the common experience of the jury (see People v. Cole (1956), 47 Cal.2d 99, 103, 301 P.2d 854).
