结局指标

主要结局

Change From Baseline in Average Daily Pain Numeric Rating Scale (NRS) Score at Week 6

时间窗: Baseline, Week 6

Participants assessed their average daily pain during the past 24 hours on an 11--point NRS ranging from 0 (no pain) to 10 (worst possible pain) with lower scores indicating less pain. Week 6 score was calculated as the mean of average daily pain NRS scores over the past 7 days. The change from baseline was calculated using difference between Week 6 mean score and Baseline mean score.
