Variables | Sensitivity/Specificity | PPV/NPV | LR | ROC AUC |
---|---|---|---|---|
Pulmonary artery size ≥ 2.9 | 59/73 | 87/37 | 2.1 | 0.71 |
PA/Ao ratio ≥ 1 | 54/74 | 87/40 | 2.2 | 0.73 |
RV/LV ratio | 55/53 | 76/30 | 1.2 | 0.54 |
Right ventricle wall thickness ≥ 3.5 mm | 65/67 | 88/35 | 1.9 | 0.74 |
Hepatic vein reflux, present/absent | 41/85 | 89/35 | 2.7 | 0.73 |
PPV: positive predictive value; NPV: negative predictive value; LR: likelihood ratio; ROC AUC: receiver-operator characteristics area under the curve; RV/LV ratio: right ventricle/left ventricle transverse distance ratio; PA/Ao: pulmonary artery/aorta ratio.
