Table 2.

Outcomes of OHCA due to non-cardiac cause in patients who had witnessed bystander CPR and initial shockable rhythm.

		EMS shock	Bystander AED shock	P value
		N = 996 (94.6)	N = 57 (5.4)
Outcomes at one month	Survival	198 (19.9)	16 (28.1)	0.14
	Favorable neurological outcome (CPC = 1 or 2)	109 (10.9)	9 (15.8)	0.26

Continuous variables were compared using the Mann–Whitney U test. Categorical variables were compared using the Chi-squared test.

AED: Automated External Defibrillator, OHCA: out-of-hospital cardiac arrest, CPR: cardiopulmonary resuscitation, CPC: Cerebral Performance Category, EMS: emergency medical service.
