HAQ-DI improvements associated with patient ratings of importance. Linearly predicted HAQ-DI improvement was calculated using a mixed model that accounts for within-patient variation over time by patient response as to level of importance of changes; post-baseline patient responses were collected at 4, 12, and 24 weeks. In the patient rating scale for importance of change in function, 1 = not at all important and 7 = extremely important.
| Patient Rating for Importance | No. Ratings | Adjusted Mean Change in HAQ-DI (95% CI) |
|---|---|---|
| 1 | 2 | 0.310 (0.165, 0.455) |
| 2 | 2 | 0.335 (0.214, 0.455) |
| 3 | 9 | 0.360 (0.263, 0.456) |
| 4 | 23 | 0.385 (0.310, 0.460) |
| 5 | 61 | 0.410 (0.352, 0.468) |
| 6 | 81 | 0.435 (0.385, 0.485) |
| 7 | 210 | 0.460 (0.404, 0.515) |
