结局指标
主要结局
Percent Change From Baseline in Target Plaque Severity Score (TPSS) at Week 4
时间窗: Baseline, Week 4
Target plaque was evaluated individually for signs of induration, scaling and erythema. Each of the 3 signs was rated on 5-point severity scale ranged from 0 to 4: 0=none, 1=slight, 2=moderate, 3=marked, 4=very marked. The individual signs severity sub scores were summed to calculate TPSS. The total score varied in increments of 1 and ranged from 1 to 12, with higher scores representing greater severity of psoriasis.
