SFR for patients with RA and OA compared with the general population.
| Cohort | Fracture | SFR (95% CI) | |
|---|---|---|---|
| Women | Men | ||
| RA | Hip | 1.54 (1.40–1.70) | 1.81 (1.51–2.17) |
| Distal radius | 0.93 (0.82–1.05) | 1.29 (0.90–1.80) | |
| Hip OA | Hip | 0.61 (0.56–0.65) | 0.77 (0.69–0.85) |
| Hip* | 0.81 (0.74–0.89) | 1.10 (0.96–1.26) | |
| Distal radius | 1.04 (0.97–1.11) | 1.08 (0.91–1.26) | |
| Knee OA | Hip | 0.89 (0.85–0.93) | 1.00 (0.92–1.08) |
| Distal radius | 1.05 (1.00–1.11) | 1.11 (0.97–1.26) | |
↵* Sensitivity analysis where subjects were censored at the time of the joint replacement surgery for the hip (n = 17,914). SFR: standardized fracture rate ratio; RA: rheumatoid arthritis; OA: osteoarthritis.
