Correlations of computed tomography (CT) and echocardio graphy measures with mPAP and PVR.

	mPAP		PVR
Measurement	r	p	r	p
CT
Right ventricle wall thickness	0.47	< 0.001	0.35	0.007
Pulmonary artery size	0.37	0.003	0.28	0.03
PA/Ao ratio	0.43	< 0.001	0.36	0.004
RV/LV ratio	0.40	0.005	0.35	0.015
Hepatic vein reflux	0.53	0.001	0.58	0.001
Echocardiography

mPAP: mean pulmonary artery pressure; PVR: pulmonary vascular resistance; RV/LV ratio: right ventricle/left ventricle transverse distance ratio; PA/Ao: pulmonary artery/aorta ratio.
