Significant changes in metabolites after modified Xiaoyao San treatment were mainly related to lipid metabolism. A: Principal component analysis score map of each group; B: Gene ontology enrichment analyses; C: Human Metabolome Database classification notes; D: Partial least squares discrimination analysis between nonalcoholic steatohepatitis and modified Xiaoyao San groups. The scores of the first-ranked principal component (PC1, horizontal) and the second-ranked principal component (PC2, vertical) were used to represent the data. Samples from various experimental cohorts were represented by differently colored scatter plots, while 95% confidence intervals were visually depicted using ellipses. PCA: Principal component analysis; PLS-DA: Partial least squares discrimination analysis; HMDB: Human Metabolome Database; MXS: Modified Xiaoyao San; NASH: Nonalcoholic steatohepatitis.
