Demographic characteristics and outcome measures of general health and disease-specific questionnaires and performance tests in erosive persons (n = 80)
| Outcome | Erosive, ≥1 E phase (n = 23; 76 affected joints) | Erosive, R phase only (n = 57; 140 affected joints) | Adjusted mean differencea (95% CI) |
|---|---|---|---|
| AUSCAN pain | 8.7 (4.6) | 7.7 (4.0) | −1.0 (−3.0, 1.0) |
| AUSCAN stiffness | 2.0 (0.9) | 1.3 (1.0) | −0.7 (−1.2, −0.2) |
| AUSCAN function | 15.5 (7.9) | 13.1 (8.1) | −2.4 (−6.4, 1.5) |
| AIMS-2 pain subscale | 5.3 (2.8) | 4.4 (2.5) | −0.8 (−2.1, 0.5) |
| AIMS-2 hand/finger function | 3.9 (2.7) | 2.8 (2.2) | −1.1 (−2.2, −0.1) |
| AIMS-2 impact subscale | 2.5 (2.3) | 2.6 (2.2) | 0.1 (−1.0, 1.3) |
| SF-12 PCS | 33.2 (11.1) | 38.7 (11.1) | 5.8 (0.2, 11.5) |
| SF-12 MCS | 53.1 (9.5) | 52.9 (9.3) | −0.3 (−5.1, 4.6) |
| MHQ aesthetics subscale | 48.1 (23.7) | 54.3 (23.7) | 5.4 (−6.6, 17.3) |
Values are mean (s.d.) unless stated otherwise, stratified for the presence of erosive (E) or remodelled (R) phase with mean differences of outcome between E phase and R phase persons. E phase: eroded joint according to the Verbruggen–Veys scoring method; R phase: remodelled joint according to the Verbruggen–Veys scoring method.
aAdjusted for age and sex; PCS: physical component summary score; MCS: mental component summary score.
