ldentification of the differential metabolomics profiles of FF between PCOS and CON patients based on a volcano plot and hierarchical clustering analysis. a. Volcano plot, down-requlated and up-regulatedmetabolites in PCOS compared to CON are marked in blue and red, respectively. The -axis represents the log2 fold change of metabolites, while the Y-axis represents the fold change of the -log10 P value determined by the Student's t-test The variable importance in the projection (VIP) value is represented by the dot size. b. Heatmap of the hierarchical clustering analysis.There are 77 distinct metabolites presented
