Fig. 2From: A prediction model based on DNA methylation biomarkers and radiological characteristics for identifying malignant from benign pulmonary nodulesReceiver-operator characteristic (ROC) curve analysis of the three models in a training cohort. The area under the ROC curve (AUC) for each model conveys its accuracy for diagnosing malignant PNs. The prediction model produced a higher AUC value for identifying malignant PNs comparing with the panel of the three DNA methylation biomarkers and the Mayo Clinic modelBack to article page
