结局指标
主要结局
Change From Baseline to Endpoint in Mean Pain, Scored Daily on a on an 11-point (0-10) Numeric Rating Pain Scale (NRPS), Where 0 = no Pain and 10 = Worst Possible Pain
时间窗: 17 weeks
Endpoint mean pain was defined as the mean of the last 4 available pain scores in the last 7 days of the treatment period. Likewise, baseline mean pain was defined as the mean of the last 4 available pain scores in the last 7 days of the baseline period.
