The screening criteria were VIP >1 and p < 0.05 of t-test. VIP (Variable important in projection): The VIP value from the OPLS-DA model, the larger the VIP, the greater the contribution of this variable to the grouping. Log2 (FC): The ratio of the mean expression levels of metabolites in the two groups of samples, with positive values indicating up-regulation and negative values indicating down-regulation.
