  1. Coronary artery bypass grafting (CABG), extracorporeal cardiopulmonary resuscitation (ECPR), Glasgow Coma Scale (GCS), Interquartile range (IQR), number (N), out-of-hospital cardiac arrest (OHCA), percutaneous intervention (PCI), pulseless electrical activity (PEA), return of spontaneous circulation (ROSC), renal replacement therapy (RRT), standard deviation (SD), ventricular fibrillation (VF), ventricular tachycardia (VT)
  2. Categorical variables were compared primarily using χ2, or Fisher’s exact test when there were few observations (i.e., < 10 per group). Continuous variables were compared using Student’s t-test, or Wilcoxon rank sum test for not normally distributed data. A two-sided p-value < 0.05 was considered statistically significant for all analyses
