Radiographic severity of Rheumatoid Arthritis in African Americans: Results from a multicenter observational study

Abstract

To our knowledge, this is the largest radiographic study of African American RA patients. Damage occurs early in the disease and is associated with radiographic progression at 3 years of disease duration. The CLEAR Registry will provide a valuable resource for future analyses of genetic, clinical, and environmental factors associated with radiographic severity of RA in African Americans.
