Cox Proportional Hazards Model Parameter Estimates for Recovery of Total Cholesterol at 3 Months Post-LVAD Implantation as a Binary Variable

Variable	Hazard Ratio	95% Confidence Interval	P Value
Cholesterol recovery at 3 mo (change ≥median)	0.241	0.092–0.628	0.004
Age at implant, per 1 y	0.983	0.954–1.014	0.28
Ischemic HF cause	0.560	0.242–1.299	0.18
Bridge to transplantation strategy	0.661	0.291–1.502	0.32
Left ventricular ejection fraction at baseline, per 1%	1.040	0.975–1.110	0.23
Baseline cholesterol, per 1 mg/dL	0.986	0.975–0.997	0.01

Wald χ²=14.1, 6 degrees of freedom, P for model fit=0.0285, n=129 (34 events). HF indicates heart failure; and LVAD, left ventricular assist device.
