†95% CIs are based on Wilson with continuity correction. ppPASI75/90/100 response is defined as ≥75/90/100% improvement in the ppPASI score from the baseline. ppIGA response is defined as a ppIGA score of 0 (cleared) or 1 (almost clear/minimal) AND ≥ 2-grade reduction from the baseline in the IGA score. PASI75/90/100 response is defined as ≥75/90/100% improvement in PASI score from baseline. In the calculation of the ppPASI, the pustules score is considered 0 and the index has a maximum score of 48. CI, confidence interval; DLQI, Dermatology Life Quality Index; PASI, Psoriasis Area and Severity Index; ppIGA, palmoplantar Investigator’s Global Assessment; ppPASI, palmoplantar PASI; q8w, every 8 weeks.
