Primary Outcome Measures
NameTimeMethod
The Percentage of Subjects Who Completed the 14-day Double-blind Phase.14 days

The indicator variable was 1 = completion, and 0 = noncompletion. For the primary efficacy analysis, the percentage of subjects who completed the double-blind phase was computed with its 95% confidence interval (CI) for each treatment regimen (starting dose of BTDS 10 or BTDS 20) across and within baseline Vicodin® stratum (15 to 22.5mg/day vs \>22.5 to 30 mg/day as determined by the daily average hydrocodone dose during the run-in period).
