SIRT2 and type 2 diabetes mellitus: Post hoc pairwise comparisons with Bonferroni correction confirmed that SIRT2 levels were significantly higher in T2DM − N compared with controls (p = 0.007), markedly higher in T2DM + N compared with controls (p < 0.001), and significantly higher in T2DM + N compared with T2DM − N (p = 0.007).
