The test results showed greater 24-h urine proteinuria (6.1 g vs. 4.4 g, p < 0.001) and elevated FFA levels (0.39 mmol/L vs. 0.33 mmol/L, p < 0.001) in the AKI group compared to the non-AKI group, whereas albumin (21.2 vs.23.6 mmol/L, p < 0.001) and HDL levels (1.57 mmol/L vs. 1.71 mmol/L, p = 0.006) were obviously decreased. Here, ALB is linked to acute kidney injury.
