Metabolite clustering tree and VIP bar plot. Each column represents a sample, and each row represents a metabolite. The denser the branch of the metabolite clustering tree, the more similar the expression patterns of all metabolites in the sample. In the histogram of VIP metabolites, the length of the blue bar indicates the contribution of metabolites to the difference between the two groups, the color of the VIP bar indicates the significance of the difference between the two groups of metabolites, and the lower the P value is, the darker the color (*P < 0.05, **P < 0.01, ***P < 0.001)
