How is the substantial evidence standard applied in medical malpractice cases?

"In both jury and nonjury trials, factual findings made by the trier of fact are generally reviewed for substantial evidence. [Citations.] Factual issues may be reviewed de novo when the facts are uncontroverted and only one deduction or inference may reasonably be drawn. [Citation.]" (Ermoian v. Desert Hospital (2007) 152 Cal.App.4th 475, 500-501.) "Under the substantial evidence standard of review, our review begins and ends with the determination as to whether, on the entire record, there is substantial evidence, contradicted or uncontradicted, which will support the trial court's factual determinations. [Citations.] Substantial evidence is evidence of ponderable legal significance, reasonable in nature, credible, and of solid value. [Citation.] The substantial evidence standard of review applies to both express and implied findings of fact made by the court in its statement of decision. [Citation.]" (Id. at p. 501.)
