Accurate ultrasonography-based portal pressure assessment in patients with hepatocellular carcinoma

Figure 1 Correlation between portal pressure gradient and hepatic venous pressure gradient in the overall group. A: Paired t-test showed that there was no significant difference between hepatic venous pressure gradient (HVPG) and portal pressure gradient (PPG); B: Scatterplot shows agreement between PPG and HVPG; C: Bland-Altman plot shows the difference between PPG and HVPG.

Figure 2 Correlation between portal pressure gradient and estimated portal pressure gradient in the overall group. A: Scatterplot shows agreement between portal pressure gradient (PPG) and estimated PPG (ePPG); B: Bland-Altman plot shows the difference between PPG and ePPG.

Figure 3 Diagnostic performance of estimated portal pressure gradient for portal pressure gradient. A: Receiver operating characteristic curves of estimated portal pressure gradient (PPG) for predicting PPG in the training and validation cohorts (n = 102 and n = 20, respectively); B: Receiver operating characteristic curves of the HVPG_CT score. AUC: Area under curve; HVPG_CT score: CT-based portal pressure score.
