| OA vs RA | 3.39 (1.25–9.20) | 0.02 |
| White vs nonwhite | 0.34 (0.12–0.95) | 0.04 |
| Preoperative BMI > 30 vs ≤ 30 | 0.89 (0.38–2.05) | 0.78 |
| Preoperative SF-36 PCS | 0.99 (0.92–1.05) | 0.68 |
| Preoperative WOMAC pain | 1.04 (1.00–1.08) | 0.03 |
| Preoperative WOMAC function | 0.97 (0.93–1.01) | 0.10 |
| Preoperative LEAS | 1.15 (0.99–1.34) | 0.08 |
| Preoperative SF-36 MCS | 0.98 (0.95–1.02) | 0.27 |
| Preoperative EQ-5D index score | 0.87 (0.05–16.24) | 0.93 |
Multiple logistic regression controlling for diagnosis, race, BMI, SF-36 PCS, preoperative WOMAC Pain, preoperative WOMAC Function, preoperative LEAS, preoperative SF-36 MCS, and preoperative EQ-5D index score. Significant data are in bold face. OA: osteoarthritis; RA: rheumatoid arthritis; BMI: body mass index; SF-36: Medical Outcomes Study Short Form-36; PCS: physical component summary; WOMAC: Western Ontario and McMaster Universities Osteoarthritis Index; LEAS: Lower Extremity Activity Scale; MCS: mental component summary.
