CI = confidence interval; RR = relative risk.

  • Estimated from a multivariate Cox proportional hazards model adjusted for age (continuous), educational achievement (≤10, 10 to 12, >12 years), marital status (single, married/cohabiting, divorced, widowed), family history of myocardial infarction (yes/no), use of aspirin (yes/no), non-Recommended Food Score (quintiles), and total energy intake (continuous).

  • Adjusted for covariates in Model 1 and mutually adjusted for all the other low-risk lifestyle factors.

  • The Recommended Food Scores included foods with a beneficial effect on cardiovascular health. A score of 1, adding up to a maximum of 25, was assigned for regular consumption of fruits, vegetables, legumes, nuts, reduced-fat dairy products, whole grains, and fish.
