Fig 4. Relationship between maternal adiposity, intermediary metabolites and placenta-specific gene expression.

(A-C) Correlations between placental levels of αKG and maternal BMI (A) or ascorbate (B), and between αKG and CSHL1 mRNA levels (C). The relations between continuous variables were evaluated by Spearman correlations (*P < 0.05). Pre-pregnancy or first trimester BMI was used as maternal early BMI.
