Boxplots comparing mean changes in the velocity of the difference between maximum and peak CT numbers (M-P) of ground-glass nodules (GGNs) for distinguishing pre-invasive adenocarcinomas (PIAs) from invasive adenocarcinomas (IACs), solitary GGNs from multiple GGNs and pure GGNs from mix GGNs. PIAs showed a remarkably higher V. (M-P) than did IACs. Significant differences did existed between solitary and multiple GGNs, as well as between pure and mix GGNs
