title: Characteristics of responders and nonresponders to slow-acting antirheumatic drugs in juvenile rheumatoid arthritis.
abstract: A 12-month double-blind, parallel, randomized, placebo-controlled multicenter trial of D-penicillamine and hydroxychloroquine was conducted in 162 children with juvenile rheumatoid arthritis in the United States and in the Union of Soviet Socialist Republics. No statistically significant intergroup differences were detected in primary outcome variables. We investigated the possible existence of select subgroups of patients who have a higher likelihood of response to active drugs than to placebo. Using previously published criteria, each patient was classified as a responder or nonresponder, and their demographic and disease characteristics at baseline were compared. We were unable to identify a subgroup of individuals who were more likely to respond to D-penicillamine or hydroxychloroquine than to placebo.
