  1. CRC CRC patient, NC non-CRC control
  2. Mann-Whitney (MW) and Fisher’s exact test (FE) were performed to assess intra-country differences; hypotheses were two-tailed with a significance level of 0.05. Significant differences are in bold and the p value stated
  3. aHistory of colonoscopy indicates whether participants had ever had a colonoscopy with bowel preparation prior to sample collection
  4. bComorbidities included in our population profile, but not as substantial analysis covariates: hypertension, gastric ulcer, gastro-oesophageal reflux disease, insulin resistance/diabetes, thyroid disease, obesity, and hypercholesterolaemia
  5. cCurrent smoker includes participants who stopped smoking within the preceding month
