Table 2
KEGG annotation results of different metabolites in each group (A represents 16 DPA, B represents 36 DPA and C represents 48 DPA).
| Group | Diff number | Diff KEGG Annotation |
|---|---|---|
| A vs. B | 465 | 27 |

Figure 5
KEGG enrichment pathway analysis of DEGs between the three study groups (Figure A: A vs. B, Figure B: A vs. C and Figure C: B vs. C). The KEGG pathway is shown by the left Y-axis while the X-axis shows the Rich factor. A high q-value is represented by blue and a low q-value is represented by red (q < 0.05).
