Evaluation of Scleroderma Clinical Trials Consortium training recommendations on modified Rodnan skin score assessment in scleroderma

Abstract

The modified Rodnan skin score (mRSS) is a validated outcome measure for skin thickness in systemic sclerosis (SSc). Training has been shown to reduce variability in the measurement of mRSS. Our objective was to assess the inter‐ and intra‐observer variability of mRSS scoring using the proposed recommendations for training by the Scleroderma Clinical Trials Consortium (SCTC) and World Scleroderma Foundation (WSF).
