Logistic Regression Model to Quantify Effect of Penicillin Allergy on 30-Day and 90-Day Mortality Rates in Patients With MSSA Bacteremia While Adjusting for Confounders

Variable	Odds Ratio (95% CI)	P Value
30-d mortality model
Penicillin allergy	0.73 (0.29–1.84)	.51
SOFA score	1.32 (1.17–1.49)	<.01
Age > 65 y	1.91 (0.91–3.98)	.09
90-d mortality model
Penicillin allergy	0.60 (0.15–1.40)	.23
SOFA score	1.32 (1.17–1.48)	<.01
Age > 65 y	1.94 (1.01–3.78)	.05
CHF	1.96 (1.03–3.75)	.04
Cancer	2.28 (1.15–4.50)	.02

Abbreviations: CHF, congestive heart failure; CI, confidence interval; MSSA, methicillin-susceptible Staphylococcus aureus; SOFA, sequential organ failure assessment.
