One-month outcomes of all the bystander-witnessed out-of-hospital cardiac arrests (OHCAs) (n = 95,072) and those with initial ventricular fibrillation (VF) of cardiac origin (n = 11,970). Group A, advanced cardiac life support (ACLS) by emergency life-saving technicians (ELSTs) without bystander-initiated cardiopulmonary resuscitation (BCPR); Group B, ACLS by ELSTs with BCPR; Group C, ACLS by physicians without BCPR; Group D, ACLS by physicians with BCPR. CPC, cerebral performance category.
