  1. Results are shown as the mean ± SD or n (%).
  2. The percentage inside the brackets indicates either the percentage in the group with RAS ≥50% or the percentage in the group without RAS ≥50%.
  3. *CAD with stenosis ≥70% at least one coronary artery.
  4. †Data for skewed variables are shown as the median (1st quartile, 3rd quartile).
  5. RAS, renal artery stenosis; AHM, anti-hypertensive medications; BMI, body mass index; HDL, high-density lipoprotein; eGFR, estimated glomerular filtration rate; CKD, chronic kidney disease; CAD, coronary artery disease; CIMT, carotid intima-media thickness; CAP, the presence of carotid atherosclerotic plaque.
