Abstract
Longitudinal and observational studies have provided valuable information on the course, clinical outcomes, and prognostic markers in rheumatoid arthritis (RA). They reflect a complete spectrum of disease in 'true-to-life' settings, and can identify aspects of RA such as long-term outcomes and predictive markers which are not easily obtained from clinical trials. Profiles of drug therapies gained over time from these studies complement those of short-term randomized studies. Comparisons of results from early-RA cohorts show both similarities and considerable differences.
