7. Modified Sartorius Score: Change From Baseline to Each Visit for Participants in the EW/EW/EW Analysis Population

   The Sartorius Scale is used to quantify the severity of HS. Points are awarded for 12 body areas (left and right axillae, left and right sub/inframammary areas, intermammary area, left and right buttocks, left and right inguino-crural folds, perianal area, perineal area, and other): points were awarded for nodules (2 points for each); abscesses (4 points); fistulas (4 points); scars (1 point); other findings (1 point); and longest distance between two lesions (2-6 points, 0 if no lesions); and if lesions are separated by normal skin (yes-0 points; no-6 points). The total Sartorius score is the sum of the 12 regional scores. Higher scores indicate greater severity of HS. A negative change indicates decrease in severity. LOCF: The last completed evaluation from the previous visit was carried forward to impute missing data at later visits.

   Measured: Baseline (in prior phase 3 study) to Weeks 2 (first dose of adalimumab in prior phase 3 study), 4, 8, 12, 16, 20, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180, 192, 204, and 216
