Background: Although rheumatoid arthritis (RA) of varying degrees of severity has been seen in our clinics, there is no statistical evidence of the magnitude of the problem in Saudi nationals. We conducted this study to determine the prevalence of RA in the Al Qassim Region of Saudi Arabia.
Patients And Methods: Five thousand eight hundred and ninety-one Saudi adults, aged 16 years and over, were studied in a house-to-house survey in the Al Qassim Region.
