Fig. 3From: Identification and validation of diagnostic biomarkers for intrahepatic cholestasis of pregnancy based on untargeted and targeted metabolomics analyses of urine metabolite profilesVolcano plot of the differentially expressed metabolites (merged mode). The Y coordinate was -log10 (P value) and the X coordinate was log2 (fold change). Each dot represented a metabolite. Red dots were the upregulated metabolites of significant expression levels. Blue dots were downregulated metabolites of significant expression levels. Black dots were metabolites of non-significant difference. The cutoff standard was set to P value<0.05Back to article page
