We further screened metabolites by ROC analysis and calculated the area under the curve (AUC). The results showed that the AUC of the 4 key DEMs analyzed by machine learning were both 1.0, which showed an excellent prediction ability for sepsis (Fig. Receiver operating characteristic curve (ROC) analysis of the 4 DEMs. ROC curve of (
