Multivariate analysis of those variables found to be statistically significant at univariate analysis identified preoperative creatinine (P=0.001), preoperative albumin (P=0.03), preoperative leukocyte (P=0.018), preoperative NLR (P=0.007), and postoperative peak NLR (P<0.001) as independent predictors of postoperative AKI (Table 4). Here, ALB is linked to acute kidney injury.
