The relationship of concentration to body mass index and waist to hip ratio. Note: The top left charts show scatterplots with age-adjusted linear regression lines and their corresponding 95% confidence interval band depicting the association between concentration and BMI (top left) and concentration and WHR (bottom left). The chart on the right shows the age-adjusted regression line slope coefficients with their 95% confidence intervals contrasting BMI with WHR as they relate to concentration
