European League Against Rheumatism Sjogren's Syndrome Disease Activity Index and European League Against Rheumatism Sjogren's Syndrome Patient-Reported Index: A Complete Picture of Primary Sjogren's Syndrome Patients

摘要

Objective. The European League Against Rheumatism (EULAR) Sjogren's Syndrome (SS) Disease Activity Index (ESSDAI) and the EULAR SS Patient-Reported Index (ESSPRI) were recently developed. We aimed to determine whether patients' symptoms differed between patients with and without systemic involvement and if the disease-specific indices correlated with each other in primary SS.
