  1. Multivariate logistic regression was used to assess the relationship between each genetic variant and CRC risk. Adjusted mean odds ratios (OR) with 95% confidence limits are shown and those in bold indicate statistical significance. P for trend values (and P values for rs 5845 and 5859 where there are only two values) are indicated in italics
  2. aAdjusted for age and sex
  3. bAdjusted for age, sex, intake of aspirin, intake of multivitamin, family history of colorectal cancer, smoking, alcohol, intake of red meat, vegetables and fruits, and physical activities
