*Crude Odds Ratio (ORc); Crude model analysis adjusted; ¥Adjusted Odds Ratio (ORa); Multivariable model: conditional logistic regression using age in years, residence (urban, rural), education level (illiterate, primary, secondary, higher), monthly income (low, medium, high), smoking status (never smoker, Ex-smoker and current smoker), Non-steroidal anti-inflammatory drugs (yes or no), total energy intake (continuous), intakes of red processed meat and dietary fiber (both continuous), calcium (continuous), family history of colorectal cancer(yes or no).
