Is Respondent's negligence a proximate cause of injury as a matter of law?

Appellant contends that respondent's negligence was a proximate cause of appellant's injury as a matter of law. This argument calls for our [18 Cal.App.4th 26] determining whether substantial evidence supported the jury's verdict for respondent. In reviewing the evidence, we must presume the judgment is correct and that the jury drew all reasonable inferences in respondent's favor (Mock v. Michigan Millers Mutual Ins. Co. (1992) 4 Cal.App.4th 306, 322, 5 Cal.Rptr.2d 594).
