Table 2 Estimated adjusted hazard ratios for rheumatoid factor (RF) and rheumatoid arthritis (RA) in relation to CHD and CVD events in the cohort free of CHD and stroke at baseline in 1972. Table shows hazard ratio, 95% CI and p-value

From: Rheumatoid factors do not predict cardiovascular disease and mortality in the general population in the Busselton Health Survey
