Adx: unilateral adrenalectomy; ARR: aldosterone-renin ratio; PAC: plasma aldosterone concentration; CCT: captopril challenge test; SIT: saline infusion test; FUT: furosemide upright test; U-Aldo: 24 h urine aldosterone; NA: not available. The cases targeted for confirmatory testing in the PASO (primary aldosteronism surgical outcome) criteria are shown in bold.
