  1. Values are median (interquartile range) or n (%) of cases
  2. ECPR extracorporeal cardiopulmonary resuscitation, CCPR conventional cardiopulmonary resuscitation, OR odds ratio, CI confidence interval, BCPR bystander cardiopulmonary resuscitation, SR shockable rhythm, NLT no and low-flow time, CPC cerebral performance category
  3. 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)
