Identification of significant metabolotics by UPLC-HRMS. a Volcano plot to visualize differential metabolites of significance between PCOS and CON group. Metabolites with FDR adjusted p value ≤ 0.05 were highlighted with red (up-regulated) and green color (down-regulated), respectively. b Clustering analysis result using differential metabolites of significance in Student’s t-test analysis (FDR adjusted p value < 0.05)
