Change From Baseline in Brief Pain Inventory-Modified Short Form (BPI-SF) Interference Score Between Responder and Non-Responder Participants at 4 Weeks [ Time Frame: Baseline, 4 weeks ] [ Designated as safety issue: No ]
BPI-SF interference score asks about the degree to which pain interferes with mood, walking and other physical activity, work, social activity, relations with others, and sleep. BPI-SF interference score ranges from 0 (no interference) to 10 (interferes completely). Response is defined as a >=50% reduction in the Maier subscale score from baseline. The Maier subscale (Items 1,2,7,8,9,10) represents "core" symptoms of depression. Total subscale scores range from 0 (normal) to 24 (severe). Factors used for adjustment for least squares means are listed in 'Other relevant information' section.

  • Change From Baseline in the Brief Pain Inventory - Modified Short Form (BPI-SF) Average Pain Score at 8 Weeks [ Time Frame: Baseline, 8 weeks ] [ Designated as safety issue: No ]

CSFQ measures 5 dimensions of sexual behavior: pleasure; desire/frequency; desire/interest; arousal; orgasm. Lower total scores are associated with diminished sexual functioning. Total scores <=47 (men) and <=41 (women) indicate global sexual dysfunction, with all phases of sexual response cycle affected. Factors used for adjustment for least squares means are in 'Other relevant information' section.
