| DAS28-CRP | Low disease activity (%) | 5 (6.7) | 2 (2.7) | 0 (0) |
| Moderate disease (%) activity | 1 (1.3) | 14 (18.7) | 12 (16) | |
| High disease activity (%) | 0 (0) | 1 (1.3) | 40 (53.3) | |

n = 75, patients with ESR and CPR measures available at baseline and at the follow-up visit one year later.
