The variables that were significant by univariate analysis were subjected to multivariate stepwise backward logistic regression analysis (Table 3), and 4 variables were ultimately proved to be significantly associated with AKI, as follows: BS ≥200 mg/dL, hsTnI >1.6 ng/mL, albumin ≤3.5 mg/dL, and eGFR <45 mL/min/1.73 m2. This evidence concerns the gene ALB and acute kidney injury.
