Receiver operating characteristic (ROC) curve-based approach for identifying potential biomarkers and evaluating their performance using area under the curve (AOC). Seven potential/candidate biomarkers were detected: (A) four metabolites from the ESI− and (B) three from the ESI+ datasets. (C) and (D) Both datasets were fed into a supervised classification algorithm using the support vector machine classification method with the SVM built-in ranking method to determine which metabolites contributed to significant features using selected frequency %.
