Parameters	POPH (n = 30)	IPAH (n = 180)	value
Total bilirubin (μmol/L)	25.0 (17.0, 44.3)	19.0 (14.0, 28.3)	0.013
Direct bilirubin (μmol/L)	10.5 (6.0, 17.0)	6.0 (4.0, 10.5)	<0.001
Albumin (g/L)	32.88 ± 4.27	38.41 ± 5.14	<0.001
ALT (IU/L)	26.5 (17.8, 38.0)	24.0 (19.0, 32.0)	0.566
AST (IU/L)	37.5 (30.0, 44.0)	25.0 (20.0, 30.0)	<0.001

POPH, portopulmonary hypertension; IPAH, idiopathic pulmonary arterial hypertension; ALT, alanine aminotransferase; AST, aspartate aminotransferase.
