The top nine KEGG pathways of groups EEG and IEG are presented in the bubble chart. Each bubble in the bubble chart represents a metabolic pathway. The X-axis of the bubble and the bubble scale indicate the influence factor of the pathway in the topology analysis. The larger the size, the greater the influence factor; the Y-axis and the color of the bubble indicate the enrichment analysis. P value (take the negative natural logarithm, namely − log10(p), the redder the color, the smaller the P value, the more significant the enrichment degree. IEG, EEG represent intracellular and extracellular metabolites, respectively
