  Figure 1.. Scatterplots of Body Mass Index Against Blood Pressure (BP) A, Body mass index (calculated as weight in kilograms divided by height in meters squared) and systolic BP. B, Body mass index and diastolic BP. Darker red denotes higher density. The black line is a smoothed condition mean, denoting the mean systolic or diastolic BP at a given body mass index.

  Figure 2.. Smoothed Conditional Mean of Systolic Blood Pressure (SBP) Given Body Mass Index (BMI) for Sex, Age, Income, Occupation, Race/Ethnicity, and Marital Status The smoothed conditional mean was fitted with an unadjusted generative additive model. Body mass index is calculated as weight in kilograms divided by height in meters squared.

  Figure 3.. Smoothed Conditional Mean of Systolic Blood Pressure (SBP) Given Body Mass Index (BMI) for Region, Province, Educational Level, Smoking Status, Stroke History, and Antihypertensive Medication Use The smoothed conditional mean was fitted with an unadjusted generative additive model. Body mass index is calculated as weight in kilograms divided by height in meters squared.
