Fig. 3From: Radiomics-based analysis of CT imaging for the preoperative prediction of invasiveness in pure ground-glass nodule lung adenocarcinomasThe box plots show the distribution between noninvasive and invasive lesions for GGNs in the training cohort (a), testing cohort (b), and validation cohort (c). The Wilcoxon test obtained p values. The Rad-score was higher in the invasive group than in the noninvasive groupBack to article page
