- No effect modifications by BMI (median), alcohol consumption (median), menopausal status, and use of HT were observed (all P ≥ 0.7)
- Abbreviations: n number, P P value, CI confidence interval
- †Cases matched 1:1 to control subjects. EPIC (European Prospective Investigation into Cancer and Nutrition): Conditional logistic regression models were used to estimate odds ratios (OR) and 95% confidence intervals (CI) for associations between log-transformed UCB levels (log-UCB), standardized per one standard deviation (1-SD) increments, and CRC risk. The crude model was conditioned on the matching factors including study center, age at blood collection (1 year), fasting status and time (3 h intervals) at blood collection, among women, additionally by menopausal status (pre-, peri-, and post-menopausal or surgically menopausal), and hormone therapy (HT) (yes, no). The multivariable model was adjusted for level of education (none/primary school, technical/professional, secondary school, university degree), BMI, height, smoking status (never, former, current smoker), physical activity (inactive, moderately inactive, moderately active, active), alcohol consumption (g/day), dietary intakes of fiber (g/day), red meat (g/day), processed meats (g/day), dairy products (g/day), and total energy intake (kcal/day)
