Adjusted survival after non-ventricular fibrillation/ventricular tachycardia cardiac arrest. Stratified by Resuscitation Outcomes Consortium site. Early survival includes individuals surviving up to one calendar day after cardiac arrest. Later survival includes early survivors progressing to hospital discharge. Sites listed in order of unadjusted early survival in order to facilitate comparison with Figure 3. Odds ratios referenced to largest site (site 1) and adjusted for age, sex, public location, witnessed arrest, bystander CPR, bystander AED use and EMS response time. Adjusted survival varied across sites for early (p<0.001) and later survival (p=0.02). Detailed odds ratios listed in the Appendix.
