The two-piecewise regression model showed that the inflection point was 14.3% after adjusting for covariates (age, sex, comorbidity, coronary heart disease, stroke, Parkinson’s disease, WBC count, MLR, NLR, hemoglobin, albumin, AGR, serum creatinine, blood urea nitrogen, ASA classification, intraoperative blood loss, and ICU admission). This evidence concerns the gene ALB and coronary artery disorder.
