Change in the number of ideal metrics between 1981–83 and 1991–94 and subsequent risk of definite and total sudden cardiac death (SCD), coronary death, incident coronary heart disease (CHD) events, and all-cause mortality

The study sample size is different from Table 1 as it includes participants who attended examination round in 1981–83 and 1991–94, were free of CVD in 1991–1994, and had the six CVH metrics and no missing covariates at both time points. Sub-distribution hazard ratios and 95% confidence intervals were estimated using Fine and Gray (25) Cox proportional hazard models to account for competing risk, were stratified on birth date (5-year interval) to account for a birth cohort effect, and were adjusted for sex, education, and diagnosed depression in 1991–94 and the number of ideal metrics in 1981–83 examination round. Standard Cox model was used when investigating all-cause mortality.

sHRs: sub-distribution hazard ratios; HRs: hazard ratios; SCD: sudden cardiac death; CHD: coronary heart disease; CI: confidence intervals.
