A Volcano plot of VIP scores from OPLS-DA model. The green crosses represent the metabolites with VIP>1 and the grey crosses represent the metabolites with VIP ≤ 1. B Volcano plot with the univariate statistical test (−ln P) and the magnitude of the change (log2FC) of metabolites. Red points represent the metabolites with P-value < 0.05 and FC>0. Blue points represent the metabolites with P-value < 0.05 and FC < 0. Grey points represent the metabolites with P-value>0.05. C Venn diagram integrating results from volcano-plots of OPLS-DA model and univariate statistical test
