CI: confidence interval; CHD: coronary heart disease; CVD: cardiovascular disease; HDI: healthy diet indicator; HR: hazard ratio; PP: preventable proportion.
Model 1: adjusted for sex, age, cohort. Model 2: adjusted for sex, age, cohort, alcohol intake, smoking, education, household amenities score, marital status, energy intake, physical activity, vitamin supplement intake, HDI (without F&V component), fruit/vegetable intake.
Per one unit increase across six intake categories (<100 g/d, 1–200 g/d, 2–300 g/d, 300–400 g/d, 400–500 g/d, >500 g/d).
In model 2, fruit and vegetable intakes were mutually adjusted for each other.
