Combined assessment of lesion severity and area affected into single score; range: 0 (no disease) to 72 (maximal disease). Body was divided into 4 sections (head, arms, trunk, legs); each area scored by itself and scores combined for final PASI. For each section, area of skin involved was estimated: 0 (0%) to 6 (90 - 100%), and severity estimated by clinical signs: erythema, induration, and desquamation; scale: 0 (none) to 4 (exceptionally striking). Final PASI = sum of severity parameters for each section * area score * weight of section (head: 0.1, arms: 0.2, body: 0.3, legs: 0.4).

PGA of Psoriasis: score based on dermatologist's assessment of disease averaged over all lesions of head, scalp, and neck. Overall lesions were graded for induration, erythema, and scaling; range: 0 (no evidence) to 5 (severe). The sum of the 3 scores was divided by 3 to obtain a final PGA score. Higher scores indicate greater severity of disease. Assessment of clear = PGA score of 0 (no evidence).
