Reproducibility of Joint Swelling Assessments in Long-lasting Rheumatoid Arthritis: Influence on Disease Activity Score-28 Values (SEA-Repro Study Part I)

Abstract

Clinical inter- and intraobserver reliability is highly dependent on the examiner. Consequences on the DAS28 score can be substantial. Agreement with sonography is poor when both B-mode and PD are used but seems better, although low, when B-mode is used alone.
