title: The prediction of radiological destruction during the early stage of rheumatoid arthritis.
abstract: A total of 107 patients with definite rheumatoid arthritis of no longer than six months' duration were observed for three years. The radiological destruction of the hand and foot joints after the follow-up time was compared with 65 anamnestic, clinical, laboratory and radiological variables at the onset of the disease. Of the individual variables, early radiological changes in the joints showed the best correlation with the progress of joint destruction. Grip strength, ESR, serum iron, serum C1 esterase inhibitor, rheumatoid factor and old age also had prognostic value. In multiple regression analysis 15 variables explained about 50% of the variance in the progress of joint destruction.
