Death rate ratios (RR) for vascular mortality vs usual systolic blood pressure (SBP), diabetes and usual BMI at ages 35–79 years in Cuba. IHD=Ischaemic heart disease. Rate ratios (RR) adjusted for age, sex, education, province, smoking, alcohol, and BMI (when appropriate). Analyses omitted the first 5 years of follow up. Exclusions as in Table 1. For each category, area of the square is inversely proportional to the variance of the category−specific log risk, which also determines the confidence interval (CI).*Excludes lowest category of BMI
