| Parameters | Univariate | Multivariate | ||||
|---|---|---|---|---|---|---|
| B | 95% CI | P-value | B | 95% CI | P-value | |
| DPA ratio of 0–10 HU | 44.1 | 29.5–58.8 | <0.001 | 26.8 | 14.7–38.8 | <0.001 |
| PA/AA ratio | 9.4 | 0.5–18.4 | 0.039 | 7.3 | 3.0–11.5 | 0.002 |
| RV/LV ratio | 7.1 | 4.8–9.4 | <0.001 | 4.4 | 2.5–6.3 | <0.001 |
DPA ratio, decreased pulmonary perfusion area ratio; PA/AA ratio, main pulmonary artery diameter to ascending aortic diameter ratio; RV/LV ratio, right ventricular diameter to left ventricular diameter ratio; B, partial regression coefficient.
