Figure 4. Comparison in European descent subjects and African descent subjects of aldosterone/renin ratio was obtained on a restricted salt diet.

Subjects of African descent had a significantly higher aldosterone/renin ratio than subjects of European descent, regardless of hypertensive status. The multivariate regression models were adjusted for age, sex, BMI, site, serum cortisol, and 24-hour urine potassium. Data are represented in a dot plot with the mean ± SEM. The subjects were from the restricted HyperPATH subcohort. ARR, aldosterone/renin ratio).
