An evaluating instrument for RA was applied to an arbitrary example of 3847 subjects > 30 years of age. Positive screening was characterized by in any event 1 of the accompanying: 2 swollen joints for at any rate 4 back to back weeks (past/present), or potentially a determination of joint inflammation before. People with positive screening had rheumatoid factor, anticitrullinated protein antibodies, and C-responsive protein estimated, just as clinical assessment performed by a rheumatologist. Self-report of specialist analyzed RA was likewise performed. 

Results. The screening survey was applied to 2998 subjects. A positive screening was found for 783 (22.1%).
