Stratified Analysis of Baseline Global CVH Status for CHD and Stroke Combined
Global cardiovascular health (CVH) status was defined according to the numbers of ideal metrics: 0 to 2 (poor), 3 to 4 (intermediate), and 5 to 7 (ideal). In each stratum, the ratios represent the number of clinical events over the number of subjects present in the stratum. Hazard ratios and 95% confidence intervals (CIs) for intermediate and ideal cardiovascular health at baseline were estimated by Cox proportional hazard regression using poor cardiovascular health as the reference exposure category. Models were adjusted for age (where appropriate), sex (where appropriate), study site (where appropriate), education level, and living alone at baseline. The p value for interaction was obtained by including a multiplicative term in the model. CHD = coronary heart disease.
