JSN progression rate for years 1 and 2, based on linear mixed modelling, using conventional SvdH scoring and IJSTP-based scoring with and without CMC3-5
| Assessment method of JSN | Progression rate year 1 (95% CI) | p Value | Progression rate year 2 (95% CI) | p Value |
|---|---|---|---|---|
| Conventional SvdH scoring (reference) | 1.70 (0.92 to 2.49) | – | 1.47 (0.65 to 2.29) | – |
| IJSTP | 1.40 (0.58 to 2.22) | 0.59 | 1.56 (0.55 to 2.56) | 0.89 |
| IJSTP without CMC3-5 | 1.33 (0.55 to 2.11) | 0.50 | 1.36 (0.63 to 2.10) | 0.85 |
CMC3-5, third to fifth carpometacarpal joints; IJSTP, individual joint of a single time point; JSN, joint space narrowing; SvdH, Sharp-van der Heijde scoring.
