a
Models adjusted for age, sex, total energy intake, and offset term. Abbreviation is as follows: Ref, reference.
b
Models adjusted for preceding variables and education, first-degree family history of colon cancer, physical activity, vitamin/mineral use, and BMI 1 yr ago for Pattern 1, none for Pattern 2, and education for Pattern 3.
c
P value for trend was obtained for each pattern by including the tertile variable in the model as a continuous term.
