Roc curve analysis of statistically significant compounds. A–N ROC curves constructed for compounds that exhibited the most effective diagnostic performance and a moderate ability to distinguish between these two groups, as measured by an Area under the Curve (AUC) around or greater than 0.7. O Cumulative ROC curve constructed by combining all compounds that showed good/ moderate diagnostic capability. ROC and cumulative ROC curves were acquired by Metaboanalyst software
