Multivariate association of PA:A ratio and echocardiogram parameters

Echo parameter	Entire cohort* n=88		CT scan and echocardiogram performed within 50 days of each other* n=43
	β	P-value	β	P-value
RV end diastolic area	0.009	0.01	0.013	0.01
RV end systolic area	0.015	0.003	0.017	0.04
RV wall thickness	0.56	0.002	0.56	0.11
RV fractional area change	−0.49	0.05	−0.25	0.7
E/e’ lateral	0.006	0.09	0.01	0.03

Notes: E/e’ lateral indicates ratio of the early mitral inflow velocity to tissue Doppler early lateral diastolic longitudinal velocity.

^*Covariates: age, sex, race, FEV₁, diastolic dysfunction.

Abbreviations: CT, computed tomography; RV, right ventricular; FEV₁, forced expiratory volume in 1 second; PA:A, pulmonary artery:aorta.
