Associations between baseline BMI and SBP and between usual SBP and incidence of stroke types

(A) BMI versus SBP. Means are adjusted for age, sex, area, education, smoking, alcohol consumption, physical activity, and self-rated health status. The area of the squares is inversely proportional to the variance of the mean SBP. The vertical lines indicate 95% CIs. (B) SBP versus ischaemic stroke. (C) SBP versus intracerebral haemorrhage. HRs are stratified by age, sex, and area, and adjusted simultaneously for education, smoking, alcohol consumption, physical activity, and self-rated health status. Each closed square represents HR with the area inversely proportional to the variance of the log HR. The vertical lines indicate 95% CIs. BMI=body-mass index. SBP=systolic blood pressure. HR=hazard ratio.
