  1. P values < 0.05 were bolded
  2. The propensity score analysis incorporated the following variables: age, sex, BCPR, SR, ICPS, and cardiogenic cause
  3. CPC Glasgow–Pittsburgh Cerebral Performance Category, OR odds ratio, CI confidence interval, ECPR extracorporeal cardiopulmonary resuscitation, BCPR bystander cardiopulmonary resuscitation, SR shockable rhythm, TTM target temperature management, ICPS interval from collapse to pump start, IPTW inverse probability of the treatment-weighting
