Univariate analysis of preoperative patient data of OPCAB vs CCB patients. Values are presented as mean ± SD; * Data presented as median, minimum, maximum. OPCAB, off- pump coronary artery bypass; CCB, on-pump coronary artery bypass; eGFR, estimated glomerular filtration rate (ml/min/1.73 m2); EF ejection fraction; PAD peripheral artery disease.
