Relationship among aldosterone/renin ratio (AAR), ambulatory blood pressure, and left ventricular mass index (LVMI). A: AAR and LVMI, β = 0.4, P = 0.04; B: 24-hour ambulatory systolic blood pressure index (24-h SBPI) and LVMI, β = 43.3, P = 0.02; C: ARR and 24-h SBPI, β = 0.0002, P = 0.91; and D: ARR and 24-h DBPI, β = 0.0001, P = 0.97
