Abstract

Thirty (7.5%) of 401 adult rheumatoid arthritis (RA) patients were antinuclear antibody positive (ANA+) and rheumatoid factor negative (RF‐), and 15 of 16 patients who were followed for a year or longer remained so. Clinical, other laboratory, and radiographic parameters were compared among this group and 90 matched RA controls divided into ANA+RF+, ANA‐RF+, and ANA‐RF‐ groups. All groups were identical, except the ANA‐RF‐ group, which had significantly fewer nodules and less destructive disease than the other three.
