HR: Hazard ratio; CI: Confidence interval, CVD: Cardiovascular disease. HR is expressed as its estimation (95% CI). All hazard ratios (HRs) were estimated with weighting and adjustment for sex (male and female), race and ethnicity (White, Black, Hispanic and other), age, education (< high school, high school and > high school), marital status(married, unmarried and other), family income (poverty, moderate, and rich), smoking status(never, former, and now), and dietary intake (coffee, alcohol, fruits, vegetables, grains, dairy, protein foods, and energy intake) and medical insurance (covered and not covered)
*Unweighted number of participants
†Sampling weights were considered in analyses
