Multivariable logistic regression models for survival.

	ROSC	Survival to 24 hours	Survival to hospital discharge	12-month survival
Adrenaline total dose	OR 0.89; (0.83–0.97); 𝑃=0.006	OR 0.81; (0.73–0.90); 𝑃<0.001		OR 0.56; (0.36–0.85); 𝑃=0.007
Age	OR 0.95; (0.90–0.99); 𝑃=0.026	OR 0.96; (0.93–0.99); 𝑃=0.015		OR 0.97; (0.94–1.00); 𝑃=0.076
Duration of CPR	OR 0.86; (0.81–0.92); 𝑃<0.001	OR 0.92; (0.88–0.95); 𝑃<0.001	OR 0.90; (0.82–0.99); 𝑃=0.022	0.93; (0.87–1.00); 𝑃=0.001
Witnessed arrest		OR 2.56; (1.01–6.50); 𝑃=0.048		3.34; (1.05–10.65); 𝑃=0.041

Initial rhythm shockable			OR 13.41; (1.69–106.22); 𝑃=0.014
Recent history of surgery				15.42; (3.02–78.79); 𝑃=0.001

For ROSC, 80.6% of all cases were correctly classified with this model. The area under the ROC (receiver-operating characteristic) curve was 0.92 (SE 0.03 and 95% CI 0.85 to 0.96). For survival to 24 hours, 80.5% of all cases were correctly classified with this model (area under the ROC curve 0.91, SE 0.02, and 95% CI 0.85 to 0.95). For survival to hospital discharge, 85.7% of all cases were correctly classified with this model (area under the ROC curve 0.84, SE 0.085, and 95% CI 0.85 to 0.95). For survival after one year, 89.9% of all cases were correctly classified with this model (area under the ROC curve 0.93, SE 0.085, and 95% CI 0.88 to 0.96).
