Fig 5. The volcano plots of detected lipids of each set of compared groups.

Grey dots indicate lipids showing no differences in two sets of compared groups. (A) Red dots indicate DRLs in aged oocytes. (B) Red dots indicate DRLs in H₂O₂-treated oocytes. Red dots indicate detected lipid species with fold changes greater than 1.5 (p < 0.05). Blue triangles in both plots indicate common DRLs between two compared groups. FC, fold change.
