^aVIP values were obtained from cross-validated OPLS-DA models with a threshold of 1. ^bFold change was calculated as the ratio of the mean metabolite levels between two groups. ^cP values were calculated from two-tailed student's T-test or Mann–Whitney U test or with a threshold of 0.05 and 0.01. ^d↑, content increased; ↓, content decreased; ^#Compared with group A, P < 0.01; ^∗Compared with group A, P < 0.05.
