¹Energy-adjusted carbohydrate intakes were determined by the residual method. Q2 through Q5 adjusted carbohydrate intake were 43.7 to <48.9, 48.9 to <53.4, 53.4 to <59.1, and ≥59.1 g · 1000 kcal⁻¹ · d⁻¹, respectively, in men and 45.1 to <50.4, 50.4 to <55.0, 55.0 to <60.5, and ≥60.5 g · 1000 kcal⁻¹ · d⁻¹, respectively, in women. In the multivariate model 2, Cox regression models adjusted for age, ethnicity, time since cohort entry, family history of colorectal cancer, history of colorectal polyp, pack-years of cigarette smoking, BMI, hours of vigorous activity, nonsteroidal anti-inflammatory drug use, multivitamin use, energy intake (logarithmically transformed), replacement hormone use (women only), and alcohol, red meat, folate, vitamin D, calcium and dietary fiber intakes.
