Fig. 3

Linear dose–response meta-analysis of 25-hydroxyvitamin D concentration and risk of rheumatoid arthritis in men and women. Estimates are for a 25 nmol/L increment in 25(OH)D. Study-specific RRs are plotted as squares, with the area of each square inversely proportional to the variance of the logRR, and corresponding CIs are plotted as horizonal lines. The diamond represents the pooled RR and 95% credible interval. CI, confidence interval; 25(OH)D, 25-hydroxyvitamin D; NHS, Nurses’ Health Study; NSHDS, Northern Sweden Health and Disease Study; RR, relative risk
