  1. Regression coefficients, HR Hazard ratio, 95% CI confidence intervals, and P values of Cox-regression model. Sign (- or +) indicates negative or positive effect on the dependent variable. APACHE II, Acute Physiology and Chronic Health Evaluation II; CI, confidence interval; bystander CPR, bystander cardiopulmonary resuscitation; Time to ROSC, time to return of spontaneous circulation.
