The ROC curve of maximum radiodensity, skewness and predicted value of multivariate Logistic regresson to distinguish AAH / AIS from MIA in pGGOs. AAH, atypical adenomatous hyperplasia. AIS, adenocarcinoma in situ. MIA, minimally invasive adenocarcinoma. pGGO, pure ground-glass opacity. ROC curve, receiver operating characteristic curve.
