Although differential short-chain fatty acids (Butyric acid and Valeric acid) are also correlated with diabetes-related indicators after GLP-1 treatment, as shown in Figure 5B, Except that Butyric acid is strongly correlated with Blood glucose 2 hours after meal and Triglyceride and Valeric acid is correlated with Glycosylated hemoglobin, The correlation between these two short-chain fatty acids and other indexes was weak. The gene discussed is GLP1R; the disease is diabetes mellitus.
