PASI: Psoriasis Area and Severity Index. (the interpretation of PASI score differed between the studies. In most studies, the score below 10 was interpreted as mild disease, between 10 and 20 as moderate, and above 20 as severe disease.) BSA: body surface area; ↑: increased in patients; ↓: decreased in patients; NS: not significant; ND: not done; ^∗mild disease.
