- Primary Outcome Measures
Name Time Method Pain VAS (Visual Analog Scale) Response. Percentage of Subjects With a Greater Than or Equal to 30% Reduction in Pain VAS From Baseline (BOCF). Baseline to Week 14 Percentage of pain VAS responders. Subjects with a \>= 30% reduction in pain VAS from baseline to endpoint (week 14) were considered responders; all other subjects were considered non-responders. Missing data were handled using BOCF (Baseline Observation Carried Forward). The pain VAS ranges from 0 (no pain) to 100 (worst imaginable pain). The pain VAS was collected morning, afternoon and evening. Baseline is the average value recorded for the measure during the week prior to the end-of-baseline visit. Endpoint is the average value recorded for the measure during the week prior to week 14.
