What is the standard of motion in a personal injury appeal?

Counsel filed an opening brief that sets forth the facts of the case and requests this court to review the record and determine whether there are any arguable issues on appeal. (People v. Wende, supra, 25 Cal.3d 436.) Counsel advised defendant of the right to file a supplemental brief within 30 days of the date of filing of the opening brief. More than 30 days elapsed, and we received no communication from defendant. Having undertaken an examination of the entire record, we find no arguable error that would result in a disposition more favorable to defendant.
