Fig. 6: Correlation analysis of serum metabolomics and gut bacteria among male offspring.

a Heatmap showing the correlation of serum metabolomics and gut bacteria. b Network showing correlation of serum metabolomics and gut bacteria. The relative abundance of Bilophila was positively associated with L-aspartic acid, while the relative abundance of Bifidobacterium was negatively associated with L-aspartic acid. SSANYPA, (2S)-2-[(2S)-2-Aminopropanoyl]-naphthalen-2-ylamino] pentanedioic acid; ACAD,1-[(5-Amino-5-carboxypentyl) amino]-1-deoxyfructose.
