Models were adjusted for sex, age, education, cigarette smoking (pack-years), updated waist-to-height ratio and hip circumference, fruit and non-starchy vegetables and red meat intakes. Models for fried potato intake were also adjusted for non-fried potatoes; those for non-fried potatoes were adjusted for fried potatoes.
