Mean PDQ subscale change scores from baseline to Week 52 for both studies ranged from \u22121.5 to \u22124.6 (P &amp;lt; 0.0001). In Study 1, effect sizes were moderate to large on the Psychological and Physical Symptoms (\u22120.56) and Symptom Bother subscales (\u22120.84). For patients with penile pain at baseline, the effect size was large (\u22121.05) for the Penile Pain subscale. Similar effect sizes were seen in Study 2. The Psychological and Physical Symptoms and Symptom Bother subscales significantly discriminated patient improvement ratings of GAPD and degree of penile curvature at Weeks 24 and 52.<\/jats:p>\n
