In the T2DM group, the initial glucose level was 7.26 ± 0.45 mmol/l, and within 15 minutes after the insulin injection, it was increased by 1.46-fold (p = 0.003) to 10.63 mmol/l; after 30 min, it was reached a maximum value—11.73 ± 0.96 mmol/l. This evidence concerns the gene INS and type 2 diabetes mellitus.
