Fig. 5. ROC analysis for diagnostic values of differential metabolites. (a) Single variate analysis. Columns with blue color represent metabolites filtered by SVM algorithm. (b) Multivariate model using linear SVM algorithm (synephrine, salicylic acid, pregnenolone sulfate, 5-L-glutamyl-L-alanine, 3-hexanone, and nitrofurazone with mevalonic acid). AUC: area under the curve; ROC: receiver operator characteristic curve; SVM: support vector machine.
