Analysis by the Cox proportional hazards model.
Probability value for trend was computed by entering the categories as a continuous term (score variable: 1, 2 or 3) in the Cox model.
Adjusted for family history of cancer (yes or no), BMI (<18.5, 18.5–25, 25–30, ≥30 or missing), education level (age at last school graduation: <19 years, ≥19 years or missing), smoking status (never, former, current or missing), alcohol drinking (never, former, current or missing), time spent walking (<0.5 hr/day, 0.5–1 hr/day, ≥1 hr/day or missing) and five groups of consumption volume of meat, vegetables, fruit, dairy products, coffee and energy intake (quartile categories or missing).
