Fig. 6From: Integrated fecal microbiota and metabolomics analysis of the orlistat intervention effect on polycystic ovary syndrome rats induced by letrozole combined with a high-fat dietVolcanic map analysis in negative (A) and positive (B) ion modes. According to the VIP value, p value and FC value, volcano maps were drawn to display the overall distribution of the differential metabolites. The blue dots represent significantly downregulated metabolites in the ORL-PCOS group, and the red dots represent significantly upregulated differential metabolites. The black dots represent nonsignificant differential metabolitesBack to article page
