In the figure, according to the expression trend of all metabolites, it is divided into 9 expression modules, and the expression trends of metabolites that can be clustered into each module are close, a cluster with a significant trend is regarded as an important object of interest, and the metabolites displayed by the cluster are searched in the relevant data, and the top 20 metabolites with significant differences are combined to screen out the data in Table S1 a/b.
