higher in T2DM patients with DKD than those with non-DKD, and SII levels were further increased in T2DM patients with DKD-non-Alb and DKD stage 3 Alb compared to those with DKD stages 1–2 Alb, suggesting that SII might be related to DKD and its distinct phenotypes. Here, ALB is linked to type 2 diabetes mellitus.
