^badjusted for year of birth, gender, cigarettes (never, <30/day, 30+/day), education (<high school, high school graduate, some college/vocational school; college graduate/post–graduate), vitamin C, fiber, carbohydrate, total calories.

All models are additionally adjusted for other meat to so that the variables in the model sum to total intake (red and white meats).
