Data were expressed as mean ± SD, %, or median (interquartile range). APA: aldosterone producing adenoma; HT: hypertension; CVD: cardiovascular disease; BMI: body mass index; SBP: systolic blood pressure; DBP: diastolic blood pressure; serum K+: concentration of serum potassium; serum Na+: concentration of serum sodium; PAC: plasma aldosterone concentration; PRC: plasma renin concentration.
