FIGURE 3.

Changes in serum trimethylamine N‐oxide (TMAO) and its derivatives of GDM and HC. (A) The PLS‐DA scores plot of TMAO and its derivatives in serum samples of the GDM group (red) and HC group (blue). The horizontal axis represents the predicted score of the first component, which explained 20.9% of the between‐group variations. The vertical axis represents the orthogonal principal component score, which explained 18.5% of the within‐group variations. R2X = 0.442, R2Y = 0.0898, Q2 = −0.36. (B) Heatmap analysis of TMAO and its derivatives between the GDM and HC groups. (C) Quantitative comparison of serum TMAO and its derivatives between the GDM and HC groups
