Untargeted metabolomics analysis of serum metabolic signatures as novel biomarkers for gastric carcinoma

Figure 2 Receiver operating characteristic curves of differential metabolites in identification of patients with gastric carcinoma from healthy volunteers. A: Receiver operating characteristic (ROC) curve of fenpiclonil; B: ROC curve of methyclothiazide. C: ROC curve of 5-hydroxyindoleacetate; D: ROC curve of 3-pyridinecarboxylic acid; E: ROC curve of guanabenz; F: ROC curve of 2,2-dichloro-n-(3-chloro-1,4-dioxo-2-naphthyl) acetamide; G: ROC curve of epigallocatechin gallate; H: ROC curve of dimethenamid. AUC: Area under the curve.
