Vascular mortality vs usual systolic blood pressure (SBP) and usual BMI at ages 35–79 years in Cuba. 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 SBP or BMI category, area of the square is inversely proportional to the variance of the category−specific log risk, which also determines the confidence interval (CI)
