Fig. 5From: HRCT features between lepidic-predominant type and other pathological subtypes in early-stage invasive pulmonary adenocarcinoma appearing as a ground-glass noduleAbility of the mean CT value, CTR, and logistic regression model to distinguish LPA from n-LPA. Logistic regression model includes mean CT value, CTR, deep lobulation, spiculation, vascular change, and bronchial change. The AUC value (AUC = 0.840) was significantly higher than the mean CT value (AUC = 0.781) or CTR (AUC = 0.593), and the diagonal line represents the reference lineBack to article page
