| Parameters | Univariate | Multivariate | ||||
|---|---|---|---|---|---|---|
| B | 95% CI | P-value | B | 95% CI | P-value | |
| DPA ratio of 0–10 HU | 120.8 | 77.4–164.1 | <0.001 | 89.7 | 46.3–133.1 | <0.001 |
| PA/AA ratio | 29.8 | 5.0–54.5 | 0.020 | 24.5 | 9.3–39.8 | 0.002 |
| RV/LV ratio | 16.2 | 8.3–24.1 | 0.042 | 7.1 | 0.3–14.0 | 0.042 |
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.
