Regression analysis of predictors of survival

		95% CI
Variable	Odds ratio	Lower	Upper	P
Male gender	5.47	0.190	158.200	0.316
Age (years)	1.05	0.960	1.140	0.297
Arrest location	0.64	0.021	19.687	0.800
Shockable rhythm (VT/VF)	1.03	0.102	10.430	0.980
Arrest to ECMO flow time (min)	0.91	0.822	1.015	0.094
First lactate at cannulation	1.047	0.750	1.462	0.787

ECMO = extracorporeal membrane oxygenation; VF = ventricular fibrillation; VT = ventricular tachycardia.
