1 FC (fold change) denotes the fold change of metabolites between two groups; that is, LRC/NLRE, LRC/NLRE, and LRE/NLRE, which are the logarithmic values (base 2) of the mean ratio between the two groups; + indicates the latter is relatively higher, and − indicates that the latter is relatively lower.
