Cox proportional hazards regression models for the primary composite outcome by treatment duration and route^c

	Unadjusted HR	95% CI	P-value	Adjusted HR	95% CI	P-value
5–10-day treatment durationa	0.99	0.73–1.33	0.97	0.90	0.65–1.22	0.50
Oral switch antibiotic therapyb	1.05	0.82–1.36	0.70	1.19	0.92–1.55	0.19

^a N = 1,407 for unadjusted analysis of antibiotic duration, and N = 1,390 for adjusted analysis of antibiotic duration. Patients who met the composite outcome within 10 days after initiating antibiotic therapy were excluded. In the adjusted analysis, 17 additional patients were excluded due to missing hospital white blood cell count.

^b N=1,461 for unadjusted analysis of antibiotic route, and N = 1,443 for adjusted analysis of antibiotic route. In the adjusted analysis, 18 additional patients were excluded due to missing hospital white blood cell count.

^c CI, confidence interval; HR, hazard ratio.
