- Abbreviations: MUFA monounsaturated fatty acid, ω-3 PUFA ω-3 polyunsaturated fatty acid, OCFA odd-chain fatty acid, VIP Variable importance in the projection, FC fold change
- aThe variable importance in the projection (VIP) was obtained in the OPLS-DA. The values in boldface indicate VIP > 1
- bThe P-values were calculated from the nonparametric Mann-Whitney U test. The values in boldface indicate P < 0.05
- cThe fold changes (FCs) were calculated from the intra-group means of the FFA levels, with a positive value indicating a relatively higher concentration in the OB group and a negative value indicating a relatively lower concentration compared with the NW group. The numbers in boldface indicate that the absolute FC value is > 1.5
