Multivariable Model for Cardiac Transplantation

Variable	Hazard Ratio	95% CI	P-value	Reliability
RVPAS vs. MBTS^*	1.46	(0.57, 3.70)	.43	-
Lower pre-Norwood RV fractional area change, %	1.49^†	(1.12, 1.97)	.006	60%
HLHS vs. other diagnosis	0.32	(0.11, 0.89)	.029	51%
Number of pre-Norwood surgeries	5.64	(1.69, 18.77)	.005	54%

Shunt type was forced into the model.

HLHS = Hypoplastic left heart syndrome; MBTS = Modified Blalock-Taussig shunt; RV = right ventricular; RVPAS = Right ventricle to pulmonary artery shunt;;
