Outcome results

Primary

Day and Night Mean Pain Score for the Previous 24 Hours on a Nine-point Scale (0 = no Pain to 8 = Very Severe Pain) at Visit 3 (4 Weeks Following Treatment) in Comparison to Baseline.

Scoring of day and night pain for the previous 24 hours was performed on a nine-point scale (0 = no pain to 8 = very severe pain) at each visit and compared to baseline. The overall mean pain score was calculated for participants who completed the study at each visit.

Time frame: Baseline and 4 weeks

Population: Effectiveness data were analyzed using the intent-to-treat (ITT) and per-protocol (PP) populations, each of which consisted of all 519 enrolled participants.
