Objective. Presence of extra-articular manifestations (EAM) in rheumatoid arthritis (RA) is associated with more severe disease and increased mortality. Prevalence of EAM may vary in different geographic areas and in different ethnic populations. In this study we investigated the frequency of EAM in 526 RA patients from a single university hospital in Turkey.
