  1. Adjusted for age and total energy intake;
  2. Adjusted for: sex, body mass index, marital status, education attainment, household income status, use of alcohol/tobacco/non-steroid anti-inflammatory drug (NSAID), family history of CRC, history of diabetes/colon screening procedure/ high cholesterol, reported hormone replacement therapy (females only), multivitamin supplements, and physical activities;
  3. Significant 95% CI are in bold;
  4. P for trend was calculated by Mantel-Haenszel Chi-Square Test.
