- Values are median (interquartile range) or n (%) of cases
- ECPR extracorporeal cardiopulmonary resuscitation, NLT no and low-flow time, OR odds ratio, CI confidence interval, BCPR bystander cardiopulmonary resuscitation, SR shockable rhythm, CPC cerebral performance category
- 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)
