Figure 3. Relationship between systolic blood pressure and adjusted mortality rate by age group. Each square represents a multivariate estimate of mortality rates after adjusting for smoking status, alcohol use, and body mass index; the error bars show 95% CIs. The number of events in each age category are as follows: men aged 40–49 years: 137; age 50–59 years: 566; age 60–69 years: 1900; age 70–79 years: 3782; age 80–89 years: 2183; women aged 40–49 years: 128; age 50–59 years: 518; age 60–69 years: 1392; age 70–79 years: 2708; age 80–89 years: 2258.
