Values are frequencies (percentages). Framingham risk scores were stratified into 3 mutually exclusive categories: low risk (<6%), intermediate risk (6–9.9%), and high risk (≥10%). CVD indicates cardiovascular disease; SCCS, Southern Community Cohort Study.
Crude frequency distributions of categorical variables within each category of CVD risk were compared using chi‐square tests.
