Baseline characteristics of enrolled patients
Conditional survival analysis of elderly non-metastatic colon cancer patients who undergo colectomy. (A) Kaplan–Meier curves estimating overall survival for individuals who had successfully survived a duration of 0-6 years. (B) Kaplan–Meier curves estimating colon-specific survival for individuals who had successfully survived a duration of 0-6 years.
