Spearman Rho correlation between the plasma TAC and SLC23A2 blood gene expression was statistically significant for the comparison of diabetics and controls [0.294 (p = 0.027) in the T2DM vs. 0.038 (p = 0.012) in the CG], as well as for the T2DM + DR patients [0.0427 (p = 0.001)], but no significant correlation was detected for the T2DM-DR patients [0.084 (p = 0.144)]. Here, SLC23A2 is linked to type 2 diabetes mellitus.
