Table 4 shows the patients’ demographic, comorbidity, and clinical parameters according to whether their eGFR was <30 ml/min/1.73 m2 or ≥30 ml/min/1.73 m2 at hospital discharge. Patients with eGFR <30 ml/min/1.73 m2 had lower preoperative serum albumin, a lower recovery from AKI rate, and more frequently had diabetes. Here, ALB is linked to acute kidney injury.
