Clear for analysis (2 points)				<0.001
Clear to safely deliver a shock (2 points)				0.005
Safely delivers a shock and resume; compression (2 points)				0.017
Completeness for AED checklist	8 (26.7)	13 (43.3)	30 (100.0)	<0.001
Time interval from AED arrival to defibrillation (sec)				0.004

Categorical variables were expressed by (%), continuous variables by mean (standard deviation). Statistical analysis was conducted by nonparametric test. AED: automated external defibrillator.
