Prognosis analysis for the EIC and the rest class across different stages of LUSC. A–C Kaplan–Meier estimates of overall survival for the EIC and the rest class across late-stage, early-stage, and all-stage LUSC. Survival data was limited to maximum 5 years (60 months). D–F Kaplan–Meier estimates of progression-free survival for the EIC and the rest class across late-stage, early-stage, and all-stage LUSC. P-values were calculated by log-rank test. Survival data was limited to maximum 5 years (60 months). G,H Multivariate Cox regression analysis on four variables (class, gender, tumour stage, and age) for late-stage and all-stage LUSC
