Division of the patients into a training and a test set. The categorical variables are displayed by the number of patients and the percentage and the continuous variables are displayed by the mean. The different surgery types are esophageal resections (ER), hyperthermic intraperitoneal chemotherapy (HIPEC) surgeries, pylorus-preserving pancreatoduodenectomy (PPPD) or Whipple surgeries, low anterior resection (LAR) with intraoperative radiotherapy (IORT), and LAR without IORT.
