Independent risks predicting preoperative VFA of APA patients by multiple linear regression model.
APA, aldosterone-producing adenoma; ARR, aldosterone-renin ratio; BMI, body mass index; eGFR, estimate glomerular filtration rate; HOMA-IR, homeostasis model assessment for insulin resistance; HTN, hypertension; sBP, systolic blood pressure; VFA, visce fat area.
