The two tables below give the relative-risk of developing a stroke, in relation to blood pressure and body mass index. The data are based on a population of men from the USA. The values in the first table are given in comparison with the total population. The values in the second table are given in relation to the lowest BMI category (<23). In both tables the values have been adjusted for the age of the individuals.
Blood pressure [mm, Hg] 122/73 125/76 130/77 135/79 140/82 146/84 150/86
Relative risk: Stroke 0.98 1.08 1.23 1.40 1.63 1.88 2.1
BMI [Kgm-2] <23 23-25 25-27 27-30 >30
Relative risk: Stroke 1.0 1.09 1.35 1.57 2.12
