Laboratory measurements in patients with RA at visits 1 and 2 compared with matched controls
| Characteristic | Patient visit 1 | Patient visit 2 | Controls | P1 value visit 1 | P2 value visit 2 | P3 value visit 1 vs visit 2 |

| ES R (mm/h) | 46 (10–87) | 46 (5–95) | 8 (3–16) | <0.001 | 0.002 | 0.49 |
| CRP (mg/L) | 52 (7–108) | 57 (3–224) | 6 (4–9) | <0.001 | 0.001 | 0.39 |
