Multivariable HR—adjusted for total energy intake from fat and from non‐fat sources (continuous), body mass index in kg m−2 (continuous), smoking status and intensity (never; current, 1–15 cigarettes per day, 16–25 cigarettes per day, 26+ cigarettes per day; former, quit ≤10 years, quit 11–20 years, quit 20+ years; current, pipe/cigar/occasional; current/former, missing; unknown), alcohol intake (non drinkers; drinkers of 0–6 g day−1, >6–12 g day−1, >12–24 g day−1, >24–60 g day−1; women drinkers of: >60 g day−1; men drinkers of: >60–96 g day−1, >96 g day−1), diabetes status at recruitment (yes, diagnosis verified; yes, diagnosis self‐reported; not diabetic, missing status), and stratified by age (1‐year categories), sex, and centre.
