Receiver operating characteristic (ROC) curves. ROC curves of the combination of miR-19a and miR-92a, the PCA and PLS-DA model with two components, CEA, CA19–9 and others for discriminating gastric cancer patients from control subjects. Others include the PCA model with seven principal components, the PLS-DA model with three to five components and the OPLS-DA model with the only component. Abbreviations: PCA, principal component analysis; PLS-DA, partial least squares-discriminate analysis; OPLS-DA, orthogonal partial least squares-discriminant analysis; CEA, carcinoembryonic antigen; CA19–9, carbohydrate antigen 19–9
