KEGG pathway enrichment analysis of differentially accumulated metabolites. A pathway enrichment in CK vs HE; B pathway enrichment in CK vs HO; C pathway enrichment in CK vs M; D pathway enrichment in HE vs HO. The x-axis represents the enrichment factor, while the y-axis represents the P-values. The representative circles (varying from small to large) refer to increased numbers of metabolites annotated to pathways
