Tendon friction rubs in early diffuse systemic sclerosis: prevalence, characteristics and longitudinal changes in a randomizedn controlled trial

摘要

Objectives. To characterize the baseline tendon friction rubs (TFRs) in early dcSSc and to evaluate the association of change in TFR over 6 and 12 months with changes in modified Rodnan skin score (MRSS) and HAQ-Disability Index (HAQ-DI) over 12 and 24 months, respectively.
