  1. Note:‘*’ represents the -log10 (p-value) value, while ‘p-value’ represents the p-value of each KEGG metabolic pathway. The smaller the p-value is, the greater the -log (p-value). ‘a’ indicates that the same differential metabolite is involved in at least two different KEGG metabolic pathways. ‘b’ indicates that two different differential metabolites are involved in the same KEGG metabolic pathway
