Logistic regression models for predicting high and low disease activity states and need for increase in treatment intensity using mini-BASDAI*
| Response | Predictor | OR | p Value | AUC | N | 95% CI of AUC |
|---|---|---|---|---|---|---|
| High disease activity based on patient report | Mini-BASDAI | 2.47 | <0.001 | 0.91 | 194 | 0.87 to 0.95 |
| High disease activity based on physician report | Mini-BASDAI | 1.51 | <0.001 | 0.77 | 194 | 0.67 to 0.88 |
| Change in treatment | Mini-BASDAI | 1.31 | <0.001 | 0.91 | 156 | 0.64 to 0.76 |
