Figure 7. Kaplan-Meier survival analyses for overall survival (OS) and esophageal cancer-specific survival (ECSS) in stages I-III patients with esophageal cancer (EC) based on age. (A) Survival curve for OS in stages I-III EC patients. (B) Survival curve for OS in stage I EC patients. (C) Survival curve for OS in stage II EC patients. (D) Survival curve for OS in stage III EC patients. (E) Survival curve for OS based on age stratification in stages I-III EC patients. (F) Survival curve for ECSS in stages I-III EC patients. (G) Survival curve for ECSS in stage I EC patients. (H) Survival curve for ECSS in stage II EC patients. (I) Survival curve for ECSS in stage III EC patients. (J) Survival curve for ECSS based on age stratification in stages I-III EC patients. (K) Competitive risk of cancer-induced deaths and non-cancer-related deaths of stages I-III EC patients. (L) Competitive risk of cancer-induced deaths and non-cancer-related deaths of stage I EC patients. (M) Competitive risk of cancer-induced deaths and non-cancer-related deaths of stage II EC patients. (N) Competitive risk of cancer-induced deaths and non-cancer-related deaths of stage III EC patients.
