AUROC of parameters and diagnostic performance after applying optimal cut-off levels of parameters for the diagnosis of severe portal hypertension.

HVAT = hepatic venous arrival time; ITT = intrahepatic transit time; ΔHVDI = difference between inspiratory and expiratory hepatic venous damping indices; PVV = portal venous velocity; PPV = positive predictive value; NPV = negative predictive value
* P-values were calculated by McNemar tests among 4 parameters (PVV, ΔHVDI, HVAT and ITT by reviewer 1) and <0.0083 of p-value was considered as significant difference between two parameters (Bonferroni’s correction).
