Values are median (interquartile range) or n (%) of cases
CPC cerebral performance category, OR odds ratio, CI confidence interval, BCPR bystander cardiopulmonary resuscitation, SR shockable rhythm, NLT no and low-flow time, ECPR extracorporeal cardiopulmonary resuscitation
aDefined as the interval from witnessed OHCA to start of reperfusion (start of extracorporeal membrane oxygenation for ECPR or return of spontaneous circulation for CCPR)
