Persistently active disease is common in patients with rheumatoid arthritis, particularly in women: a long-term inception cohort study

摘要

Objectives: Despite improved treatment strategies for rheumatoid arthritis (RA), some patients do not respond satisfactorily. The aim of this study was to investigate the course and outcome of early RA diagnosed during the 1990s and followed for 8 years with a focus on those who did not respond well to treatment.
