Proportional Hazards Models for Bloodstream Infection Clearance

Variable	Hazard Ratio (95% CI)	P Value
Cause-specific hazard model^a
Vancomycin + cefepime	1.408 (1.125–1.762)	.003
Endovascular source	0.542 (0.418–0.703)	<.001
Subdistribution hazard model^b
Vancomycin + cefepime	1.264 (1.040–1.536)	.019
Endovascular source	0.569 (0.457–0.708)	<.001

Abbreviation: CI, confidence interval.

^aAfrican American race, unknown source, invasive prosthetic device source, bone/joint source, lower respiratory tract source, intravenous drug use, chronic hemodialysis, and acute kidney injury were all included at model entry but did not meet criteria for retention.

^aBased on the results of the cause-specific model, only vancomycin + cefepime and endovascular were included in the model.
