EMS agency matched analysis
ETI vs. BVM	0.30 (0.14–0.65)	0.17 (0.06–0.50)	1.08 (0.63–1.83)
SGA vs. BVM	0.22 (0.10–0.51)	0.10 (0.03–0.31)	0.92 (0.51–1.67)

^*Due to the small sample size for SGA in the complete case analysis, the 95% confidence interval upper limit approaches infinity. Other covariates included in the analysis include age and first recorded rhythm (shockable, asystole, PEA) for the primary and EMS agency matched analyses; age, race, who applied the AED, and the time of day of the call broken down by hour for the complete case analysis; age, first recorded rhythm and race for ≤1 year old; and age, presumed arrest etiology, and who first defibrillated for >1 year old. OR = Adjusted Odds Ratio, CI = Confidence Interval.
