Abstract

Purpose: Proper statistical analysis is an essential element in the evaluation of clinical trial outcomes. We had the informal observation that double-organ bias was a neglected issue during the statistical analyses of clinical trials on eyelid ptosis. The aim of this study was to formally document the prevalence of this bias in these studies.
