Sensitivity Analyses^a.

Outcome	Cohort	OR (95% CI)^b	P
At least one antibiotic present	Infant^c	0.52 (0.18–1.55)	.24
	Febrile UTI^d	0.28 (0.08–0.98)	.046
At least one imaging procedure performed	Infant^c	1.22 (0.38–3.92)	.73

Abbreviations: OR, odds ratio; CI, confidence interval; UTI, urinary tract infection; NAMCS, National Ambulatory Medical Care Survey; NHAMCS, National Hospital Ambulatory Medical Care Survey.

National estimates of patient characteristics and outcomes of interest for sensitivity analyses stratified by year—2008–2010 and 2012–2014. NAMCS and NHAMCS survey design was used to obtain national estimates.

Results of weighted logistic regression modeling for the 2 primary outcomes. OR given represents the indicator of a visit being before 2011 or after 2011, where before 2011 is the reference group.
