3. Figure 2
Overall survival curves of patients with p-stage IA adenocarcinoma based on tumor invasiveness proposed by the International Association for the Study of Lung Cancer, American Thoracic Society and European Respiratory Society. A significant difference was noted between noninvasive adenocarcinoma and invasive adenocarcinoma (P < .01). NRR, Number remaining at risk.
