Fig. 2From: Metabolomics analysis reveals changes related to pseudocyst formation induced by iron depletion in Trichomonas vaginalisVolcano plots of significantly changed compounds in positive (a) and negative (b) ion models. Red dots represent compounds upregulated significantly in IR cells. Blue dots represent compounds downregulated significantly in IR cells. VIP score values are indicated by the size of dots. IR, iron-rich; ID, iron-deficientBack to article page
