Receiver Operating Characteristics (ROC) curve in both cohorts. The areas under ROC (AUC) of serum TNC, SOFA, APACHE II, and SAPS II for predicting all-cause mortality were 0.803, 0.808, 0.762, and 0.779 (p < 0.001 for all) in the emergency (derivation) cohort and 0.745, 0.844, 0.846, and 0.872 (p < 0.001) in the inpatient (validation) cohort. In the emergency cohort, there was no significant difference between serum TNC and the three critical illness scores. In the inpatient cohort, the AUC of serum TNC was significantly lower than SAPS II (p = 0.032) while there was no significant difference between serum TNC and SOFA or APACHE II.
