  • aVital status is defined as the vital status for each CRC patient at their last date of follow-up, with 35% of patients with CRC deceased during the course of follow-up and 65% alive at last date of contact.

  • bEndoscopy: sigmoidoscopy or colonoscopy received at least 2 years prior to CRC diagnosis.

  • cMSI status of tumors was available for approximately 63% of patients. Percentages reported are out of the total cases with MSI status available.
