  1. When a tumor was not detected on CT and the size of tumor was shorter than 5 mm, the tumor size in statistical analyses was set at 2.5 mm
  2. BP blood pressure, eGFR estimated glomerular filtration rate, PAC plasma aldosterone concentration, PRA plasma renin activity, ARR aldosterone-renin ratio = PAC/PRA, AVS adrenal venous sampling, MW-U the Mann–Whitney U test, the unpaired t-test: uTT, S-PAL group small PA lesion group, L-PAL group large PA lesion group
