Additional file 2 of The predictive value of creatinine clearance for mortality in patients undergoing revascularization

Additional file 2: Figure S2. Distribution of CKD stages determined by eGFR according to the five different formulas. A - Among patients who underwent CABG. B - Among patients who underwent PCI. CKD = Chronic kidney disease; eGFR = estimated glomerular filtration rate; CABG = coronary artery bypass grafting; PCI = percutaneous coronary intervention; CKD-EPI = Chronic Kidney disease Epidemiology Collaboration; MDRD = Modification of Diet in Renal Disease; IB = Inulin clearance–Based equation; CG = Cockcroft–Gault
