	Hazard Ratio	95% Confidence Interval	P-Value
Donor age
<40 years old	Ref	Ref	Ref
≥40 years old	0.95	0.43, 2.13	0.904
Recipient age, increasing, per year	1.03	1.01, 1.06	0.034
Diabetes mellitus	1.02	0.56, 1.86	0.945
Prior cardiac surgery	2.38	1.32, 4.30	0.004
Total bilirubin, increasing, per 1 mg/dL	1.21	0.98, 1.48	0.071
Serum creatinine, increasing, per 1 mg/dL	1.38	0.82, 2.32	0.228
Total graft preservation time, increasing, per hour	1.14	1.01, 1.29	0.033

9 (0.9%) study patients were excluded from the final model due to incomplete data.
