Kaplan–Meier analyses of the five-gene-based model in subgroups with different clinical characteristics. Kaplan–Meier survival plot analyses to assess the efficacy of the five-gene-based model in predicting the survival outcomes of subgroups with different clinical characteristics (age, sex, T1 + T2, T3 + T4, N0, M0, stage I + II, stage III + IV, G1 + G2, and G3 + G4). Kaplan–Meier survival curves for a age > 60, b age < 60, c male, d female, e T1 + T2, f T3 + T4, g N0, h M0, i stage I + II, j stage III + IV, k G1 + G2, and l G3 + G4 for the low-risk and high-risk groups.
