Pregnancy-status-dependent lipidomics characteristics at day 14 post ovulation. (A). Distribution of whole lipidome according to their classes. (B) Volcano plot depicts the quantitative comparison between the P and NP groups. Coloured dots represent upregulated and downregulated lipids, respectively (fold-change ≥ 1.5 and p ≤ 0.05). Gray dots represent lipids that are not differentially expressed between the groups. (C) Heat map showing the lipids abundance patterns in pregnant and non-pregnant plasma. Ratio is mapped from red (increase) to blue (decrease) or white (no change); see colour key inset. Each row represents a lipid species, and each column represents a sample.
