In proportion: approaches for displaying patient-reported outcome research study results as percentages responding to treatment

Purpose Patient-reported outcome (PRO) data from clinical trials can promote valuable patient–clinician communication and aid the decision-making process regarding treatment options. Despite these benefits, both patients and doctors face challenges in interpreting PRO scores. The purpose of this study was to identify best practices for presenting PRO results expressed as proportions of patients with changes from baseline (improved/stable/worsened) for use in patient educational materials and decision aids.
