^**Restricted cubic splines, with a separate term to identify missing values if required. CM (Cardiomyopathy), PAP (Pulmonary Artery Pressure), PVR (Pulmonary Vascular Resistance), ECMO (Extra-corporeal Membrane Oxygenation), ICD (Implantable Cardioverter Defibrillator), VAD (Ventricular Assist Device), hr (hour), IV (intravenous), PRA (Panel Reactive Antibodies),

^*The reference category is M recipient-M donor. The donor-recipient BMI ratio or donor LV ejection fraction was not significant.
