In one RCT of Grenz ray therapy, 13 of 17 sides receiving Grenz ray showed greater improvement than the contralateral side; by comparison an advantage was seen in only one of 17 sides receiving placebo. The author commented that the degree of improvement was modest. One of two RCTs comparing colchicine with placebo claimed benefit from the former but at the expense of troublesome side-effects. There is no good evidence from RCTs to support the use of tar or anthralin. There are no RCTs of methotrexate therapy for chronic palmoplantar pustular psoriasis.
