Abstract
When a community-derived population of 840 rheumatoid arthritis patients was used to test the American Rheumatism Association's 11 diagnostic criteria for rheumatoid arthritis, these criteria divided patients into 3 reasonably distinct classifications (probable, definite, and classic). The severity of disease increased in direct proportion to the number of positive criteria. Three criteria involve invasive procedures that are rarely performed; they are unnecessary for effective use of the other 8 criteria. Although 256 possible combinations of these 8 criteria exist, the criteria function principally to classify patients into only 7 major clinical syndromes, each of which corresponds to a major clinical presentation. By identifying the logical interrelationships between criteria in this report, we have confirmed their applicability and provided insight into the manner by which criteria classify patients.This publication has 5 references indexed in Scilit:
