Early rheumatoid disease. II. Patterns of joint involvement.
Data from the first research clinic visit (Fleming and others, 1976) have been subjected to factor analysis to identify early patterns of joint involvement. Nine patterns emerged. Two patterns, if present early, were found to have prognostic significance. An eventually more severe disease was associated with a pattern of large joint involvement (shoulder, elbow, wrist, knee) and a pattern based on metatarsophalangeal joints I and III.
