a
High: consumption above or equal to the study- and sex-specific median value; low: consumption below the study- and sex-specific median value; moderate: consumption higher than zero but below or equal to the study- and sex-specific median value.
b
Estimated from logistic regression models adjusted for age, sex, calendar period, centre, education, body mass index, occupational physical activity, family history of intestinal cancer, and total energy intake.
