Analysis in this table was made using imputed data.

*Model of biomarkers selected through backwards stepwise elimination using multivariable logistic regression analysis.

AUC, area under the curve; hs-cTnT, high-senstivity cardiac troponin T; log, logarithm; NT-proBNP, N-terminal pro-B-type natriuretic peptide; PCT, procalcitonin.
