ROC curve analysis for discriminating NSCLC from controls. Receiver-operating characteristic curve analysis of expression levels of the six miRNAs (miR-21, miR-125b, miR-155, miR-375, miR-31, and miR-210) in tissues of 52 NSCLC patients. miR-21, miR-210, and miR-31 produced 0.950, 0.875 and 0.841 area under the curve (AUC) values, respectively, which are higher than AUC values from the other miRNAs
