Spearman Rho correlation between the plasma MDA/TBARS values and SLC23A2 blood gene expression was statistically significant [0.290 (p = 0.026) for the T2DM and 0.188 (p = 0.048) for the CG, and 0.651 (p = 0.030) for the T2DM + DR vs. 0.711 (p = 0.0002) for the T2DM-DR]. Here, SLC23A2 is linked to type 2 diabetes mellitus.
