Results for the final multivariate hand model
| Explanatory variable | OR (95% CI) | p Value | |
|---|---|---|---|
| Joint-specific activity variables | EWMA | 1.40 (1.25 to 1.56)* | <0.001 |
| PROP | 1.33 (1.20 to 1.48)* | <0.001 | |
| Swelling at any visit | 1.63 (1.35 to 1.97) | <0.001 | |
| Global activity variable | Swelling in the same hand at any of most recent 3 visits | 1.55 (1.30 to 1.84) | <0.001 |
| Damage variables | Damage in the symmetric joint | 2.24 (1.79 to 2.80) | <0.001 |
| Damage in an adjacent joint | 1.53 (1.22 to 1.91) | <0.001 |
↵* The OR for the exponentially weighted moving average (EWMA) (an estimated probability) and proportion of visits with activity observed in the joint (PROP) are scaled to represent the effect for an increase of 0.25 on these (0–1) scales.
