  1. Values are given as n (%) or median (interquartile range). CCS: chronic coronary syndrome; ACS: acute coronary syndrome; SA: stable angina; PCI: percutaneous coronary intervention; CABG; coronary artery bypass grafting; VD: vessel disease; LDL: low density lipoprotein; oxLDL: oxidized LDL; HDL: high density lipoprotein; TAC: total antioxidant capacity; PBMC: peripheral blood mononuclear cell; UAE: uric acid equivalents
  2. a Four patients had a previous history of PCI followed by CABG
  3. b Severity of coronary artery disease is indicated as ≥ 50% luminal narrowing in one, two or three major epicardial coronary arteries (i.e., the right coronary artery, left anterior descending artery, and left circumflex artery). Bolded P-values represent statistical significance
