There were significant differences between groups in patient age, department distribution, complications (lung disease, malignancy, and CKD), CCI, AKI risk factors (usage of contrast agent, chemotherapeutic agent, heart failure, sepsis, surgery), AKI stage, and laboratory parameters (hemoglobin, platelet, albumin, total bilirubin, urea nitrogen, and eGFR) (Table 1). This evidence concerns the gene ALB and acute kidney injury.
