Cardiopulmonary changes and its association with clinical features in noncirrhotic portal hypertension

Figure 1 Consort diagram of the cohort. Portal hypertension was defined by presence of gastric, esophageal, or ectopic varices, portal hypertensive gastropathy, or the presence of ascites or portosystemic shunting in imaging. NCPH: Noncirrhotic portal hypertension; RVSP: Right ventricular systolic pressure; LVDD: Left ventricular diastolic volume; LVSD: Left ventricular systolic volume.

Figure 2 Performance of liver-related criteria to screen for shunting. Wilson-Brown method was used to calculate the confidence interval of test characteristics. PPV: Positive predictive value; NPV: Negative predictive value; AUROC: Area under receiver operating characteristic; IPVD: Intrapulmonary vascular dilatation; AST/ALT: Aspartate aminotransferase to alanine aminotransferase.
