Figure 6G of the correlation study revealed that Odoribacter was inversely connected with OGTT, TNF-α, IL-6, IL-1β, and other physiological and biochemical markers of T2DM (p < 0.05), while Proteus was favorably correlated with IL-1β, IL-6, and TNF-α (p < 0.01) and strongly correlated with TNF (p < 0.001). This evidence concerns the gene TNF and type 2 diabetes mellitus.
