Observed at ES mode [M − H]; bobserved at ES+ mode [M + H]+.
: content increased; : content decreased.
dFold change was calculated as the ratio of the mean metabolite levels between two groups. A positive value of fold change indicates a relatively higher concentration of metabolites, while a negative value of fold change indicates a relatively lower concentration of metabolites in model rats as compared to normal rats.
e values were calculated from two-tailed Mann-Whitney test with a threshold of 0.05.
