The odds ratio (95% confidence intervals) of those with high disease activity among patients with and without nocturnal pain. (High disease activity defined as six or more tender joints, three or more swollen joints, ESR > 28mm 1st h, CRP > 20 mg/l). The odds ratio for radiographic scores above the median value are also included in the table
| Odds ratio | 95% Confidence intervals | |
|---|---|---|
| Joint tenderness | 7.88 | (3.23, 19.18) |
| Swollen joints (n) | 4.61 | (2.41, 8.79) |
| CRP | 2.36 | (1.19, 4.70) |
| ESR | 2.15 | (1.20, 3.85) |
| Radiographic score | 0.94 | (0.46, 1.94) |
