Diagnostic outcomes are shown via receiver operating characteristic (ROC) curves for CAD severity. a ROC of the random forest classifier using CAG + serum metabolite modules based on the most important variables by ranking the variables by importance in the discovery phase among 201 subjects. b The detailed explanatory variables based on the random forest model in each comparison. The lengths of the bars in the histogram represent the mean decrease accuracy, which indicates the importance of the CAG or metabolite module for classification. c ROC of the cross-validated random forest classifier using the most important explanatory variables in the validation cohort.
