De-Ritis Ratio Is Associated with Mortality after Cardiac Arrest

Table 6

Comparison of different prognostic models on CA patients.

Model predictors	Likelihood ratio test	AIC	value	AUROC
ICU mortality
Model 1	53.58	476.37	<0.001	0.715
Model 2	68.45	463.50	<0.001	0.738
Hospital mortality
Model 1	52.41	470.81	<0.001	0.714
Model 2	74.86	450.36	<0.001	0.752
Unfavorable neurological outcome
Model 1	45.26	468.82	<0.001	0.700
Model 2	64.96	451.12	<0.001	0.736

Abbreviation: AIC: Akaike information criterion; AUROC: area under the receiver operating characteristics curve. Model 1 included age, sex, adrenaline, bystander CPR (yes/no), and serum lactate level at admission. Model 2 included model 1 plus the De-Ritis ratio.
