Why the study?
Extra-articular manifestations of rheumatoid arthritis are major predictors of premature mortality, but their prevalence and correlation with disease activity and duration required determination.
In adult patients with rheumatoid arthritis, extra-articular manifestations are highly prevalent (78.7%) and are significantly predicted by increased disease activity, disease duration, and high positive rheumatoid factor levels.

May support screening for extra-articular RA manifestations in active disease; leaves open causal links pending longitudinal studies.
