Concerning laboratory data, baseline serum creatinine, RDW, NLR and PLR in the CA-AKI group were higher than those in the non-CA-AKI group (P < 0.0001), while eGFR (61.12 vs 84.38 ml/min, P < 0.0001), hemoglobin (112 vs 131 g/L, P = 0.0039), red blood cell count (4.12 ± 0.79 vs 4.42 ± 0.65, P = 0.021, and albumin (33.9 vs 39.5 g/L, P < 0.0001) at baseline were significantly lower than those in the non-CA-AKI group. This evidence concerns the gene ALB and acute kidney injury.
