Outcome analysis comparing empiric β-lactam versus vancomycin, adjusted for age, age-adjusted Charlson-comorbidity index, infectious diseases consultation, infective endocarditis and time to receipt of empiric antibiotics

Outcomes	Crude OR (95 % CI)	p value	Adjusted OR (95 % CI)	p value
28-day mortality	0.60 (0.23–1.55)	0.29	0.85 (0.27–2.67)	0.78
90-day mortality	0.56 (0.28–1.15)	0.11	0.88 (0.36–2.17)	0.79

	Ratio of mean (95 % CI)	p value	Adjusted ratio of mean (95 % CI)	p value
Duration of bacteremia	0.77 (0.64–0.93)	0.01	0.77 (0.62–0.95)	0.01
Hospital length-of-stay	0.85 (0.68–1.07)	0.16	0.86 (0.66–1.10)	0.23

Duration of bacteremia was further adjusted for surgical source control
