| Null hypothesis: the difference in 24-hour average pain score between duloxetine and placebo treatment groups at last visit of treatment phase is zero. This study will have at least 80% power to detect a treatment group difference of 1.0 point in the baseline-to-endpoint mean change on the weekly mean of 24-hour average pain severity between duloxetine and placebo treatment groups based on Baseline Observation Carried Forward (BOCF). | Mixed-Effects Model Repeated Measures | No adjustments for multiple comparisons were made. | <0.001 | P-value for treatment effect at last visit. Effects evaluated based on 2-sided significance level=0.05.
