Correlation analysis of different gut microbiota, metabolites and behaviors. a Procrustes analysis of serum metabolome and gut microbial. b Spearman correlation analysis of different gut microbiota and metabolites in serum. c Multivariate analysis of the relationship between the whole set of variables. d The contribution of taxa that explain the variation of the metabolite hypoxanthine; The dashed line to the left represents negative contributions and the dashed line to the right represents positive contributions. e–f The prediction of changes in key metabolite levels by community-level metabolic potential scores (CMP) is shown, respectively. g Diffusion analysis of differential metabolites in FELLA. h Map of differential metabolite quantities from different sources. i Visualization of nodes of the key metabolite hypoxanthine in the purine metabolic pathway. j Spearman correlation analysis of key metabolites and behavior performance. *P < 0.05, **P < 0.01
