Association of pathological and imaging features with risks predicted by the nomogram

We further examined the prediction value of the nomogram in subgroups of stage IA patients with different pathological and imaging features. We found the RFS of high‐risk patients was significantly worse than that of the low‐risk patients in subgroup analysis of different pathological features (Kaplan–Meier curves of recurrence‐free survival (RFS) for risk stratification, lepidic lung adenocarcinoma (LUAD), acinar LUAD and papillary LUAD (left), and micropapillary LUAD and solid LUAD (right).Kaplan–Meier curves of recurrence‐free survival (RFS) for risk stratification and the groups of the different tumor stages.
