The Different Effects of Direct Bilirubin on Portopulmonary Hypertension and Idiopathic Pulmonary Arterial Hypertension

Figure 3

Comparison of estimated survival between IPAH and POPH in total patients (a). When divided by the upper limit of the normal range of direct bilirubin (both IPAH and POPH), the different survival situations between POPH and IPAH patients with direct bilirubin <7 μmol/L (b) and patients with direct bilirubin ≥7 μmol/L (c). POPH, portopulmonary hypertension; IPAH, idiopathic pulmonary arterial hypertension.
