Change from baseline in mean daily average pain score during double-blind treatment period and follow-up period (full analysis set). The mean daily average pain score assessed by the Numeric Rating Scale, which consists of a single question that asks patients to record their daily average pain on an 11-point scale (ranging from 0=no pain to 10=pain as bad as you can imagine) over the previous 24 hours. Data from the double-blind period are presented as LS mean ± standard error; data from the follow-up period are presented as mean ± standard error. *Indicates P<0.05.
