Fig. 2From: Growth characteristics of early-stage (IA) lung adenocarcinoma and its value in predicting lymph node metastasis(A-B) Box plot shows VDT and MDT for the whole nodule of PSN and SN. The median VDTt and MDTt of SN was significantly shorter than pSN. (C-D) Box plot shows the solid component of PSN and SN. The median VDT and MDT of SN was significantly shorter than the solid component of pSN. ∗ represent p < 0.05. ∗∗ represent p < 0.01. pSN, part-solid nodules. SN, solid nodules. VDTt, volume doubling time of the whole nodule. MDTt, mass doubling time of the whole nodule. VDTc, volume doubling time of the solid component. MDTc, mass doubling time of the solid componentBack to article page
