Course of the modified Rodnan skin thickness score in systemic sclerosis clinical trials: Analysis of three large multicenter, double‐blind, randomized controlled trials

Abstract

Our study confirms recent findings that in patients entered into these 3 RCTs, skin thickening did not follow the same trend in natural history as that seen in the dcSSc populations entered into early, open longitudinal studies previously reported. These findings have important implications for study design, in which "prevention of worsening" is the main objective.
