The ‘Analyzed cat.’ column refers to categories which are compared to reference categories in terms of odds of death. AIC – Akaike Information Criterion; BIC – Bayesian Information Criterion; β_i – regression coefficient; SE – standard error; OR – odds ratio; CI – confidence interval. The ‘AUC (learning)’ and ‘AUC (testing)’ columns show AUC values from 10-fold cross validation.
