Receiver-operator characteristic (ROC) curve analysis of expression levels of the four miRNAs in sputum of 36 patients diagnosed with stage I lung adenocarcinoma and 36 health subjects. The area under the ROC curve (AUC) for each miRNA conveys its accuracy for differentiation of lung adenocarcinoma patients and healthy subjects in terms of sensitivity and specificity. The individual genes produce 0.822-0.846 AUC values (A-D), being significantly lower than 0.896 AUC by the four genes combined as a marker panel (E) (All P<0.05).
