Operative characteristics and renal function, classified by CKD stages or proteinuria.

Comparison with patients with preserved estimated GFR (≥60 ml/min/1.73 m2) or no proteinuria: *p<0.05; **p<0.01; and ***p<0.001.
Abbreviations; CABG: coronary artery bypass grafting surgery; CKD: chronic kidney disease; eGFR: estimated glomerular filtrating rate; ESRD: end stage renal disease.

与估算肾小球滤过率（estimated GFR）保留（≥60 ml/min/1.73 m²）或无蛋白尿的患者进行对比：*p<0.05；**p<0.01；***p<0.001。
缩写说明：CABG：冠状动脉旁路移植术（coronary artery bypass grafting surgery）；CKD：慢性肾脏病（chronic kidney disease）；eGFR：估算肾小球滤过率（estimated glomerular filtrating rate）；ESRD：终末期肾病（end stage renal disease）。
