Multivariable logistic regression model for ulcer detection by TOF-MRA among ulcers detected by CE-MRA
| Characteristic | Multivariable | ||
|---|---|---|---|
| OR | 95% CI | P | |
| Orientation (distally pointing vs perpendicular) | 5.57 | 1.08–28.65 | 0.04 |
| Orientation (proximally-pointing vs perpendicular) | 0.21 | 0.14–0.29 | <0.001 |
| Location (proximal vs isolevel)a | 2.79 | 0.94–8.32 | 0.06 |
| Location (distal vs isolevel)a | 5.17 | 2.10–12.70 | <0.001 |
| Neck-to-depth ratio | 1.96 | 1.11–3.45 | 0.02 |
| Volume index | 1.01 | 1.00–1.02 | 0.06 |
| Degree of stenosis | 0.97 | 0.94–1.01 | 0.23 |
Note:—Robust variance estimate was used to account for 2 readers' results for each ulcer.
