The urinary excretion of NAG showed no differences between the two examined groups (3.547 (1.915–5.123) U/g creatinine versus 3.210 (2.000–3.835) U/g creatinine, p = 0.202), whereas the median value of NGAL was significantly increased in T2DM patients with p = 0.025 (Figure 3). This evidence concerns the gene LCN2 and type 2 diabetes mellitus.
