Association between the immune prognostic model (IPM) and other clinicopathologic variables of early‐stage lung adenocarcinoma (LUAD) patients in the TCGA cohort. (A) Forest plot of univariate and multivariate Cox regression analysis to assess the association between IPM and conventional prognostic factors. (B) The C‐indexes were estimated to compare the prognostic efficiency between the IPM and other traditional clinical variables. (C) Nomogram for predicting 3‐, 5‐, and 10‐year OS for early‐stage LUAD patients. (D) Calibration curve of nomogram concerning consistency between predicted and observed 3‐, 5‐, and 10‐year outcomes in the TCGA cohort. Gray line at 45° represents perfect prediction, and red line represents the actual performances of the nomogram. C‐index, Concordance index
