Does a failure to include express findings on all relevant facts in the judgment of a jury?

11 An appellate court may affirm on the basis of any evidence in the record that supports the trial court's judgment. The failure to include express findings on all relevant facts "does not require remand if a complete understanding of the issues may be had without the aid of separate findings." Swanson v.
