Fig. 9

The network summary of microbial-metabolite association. Colored squares represent metabolic pathways. Diamonds and circles depict metabolites and microbes, respectively, that have shown significant differences in abundance. Nodes frames are colored red and blue to indicate up-regulation and down-regulation, respectively. Connections between nodes are illustrated with lines, where red and blue lines represent positive and negative correlations, respectively. Darker shades of red and blue lines denote correlations that are significantly strong
