From: Detection of serum MMP-7 and MMP-9 in cholangiocarcinoma patients: evaluation of diagnostic accuracy
ROC curve analyses of CEA, CA19-9, MMP-9 and MMP-7 for the diagnosis of cholangiocarcinoma. The diagnostic accuracy of each biomarker, in terms of its sensitivity and specificity, are presented by receiver operating characteristic (ROC) curve analysis. Figures 2A, 2B, 2C and 2D correspond to CEA, CA19-9, MMP-7 and MMP-9. Only the area under the curve (AUC) of the ROC for MMP-7 is significantly higher than a chance value (0.5).
