The results registered in Table 2 showed significant differences between individuals with T2DM compared to individuals with MDD and SZ for IL-10 at TB (p < 0.0001; η2p = 0.14), as well as between the those with HC and SZ for TNF-α at TY (p < 0.05; η2p = 0.08); individuals with SZ obtained significantly higher scores for both biomarkers. This evidence concerns the gene IL10 and major depressive disorder.
