Quantitative values are expressed as the mean±SD or median (IQR). Categorical variables are expressed as the number (percentage).
When comparing the non-ROSC achievement group and the ROSC achievement group, p values of <0.05 were considered significant.
BSCPR: bystander cardiopulmonary resuscitation, PAD: public access defibrillation, ACC-CPR: automated chest compression cardiopulmonary resuscitation, CPC: cerebral performance category, CPR: cardiopulmonary resuscitation, ED: emergency department, ROSC: return of spontaneous circulation, IQR: interquartile range
