ALB and type 2 diabetes mellitus: Gao et al. [35] used urinary albumin/creatinine ratio, plasma albumin, and other markers to predict renal function decline in patients with type 2 DKD, and revealed a valuable predictive significance; and the study of Ideet al. [36] also demonstrated that urinary tubule injury markers including UCR and their combination were significant predictors for the future eGFR decline in patients with type 2 diabetes.
