Spearman’s correlation between placental mRNA expression and increasing order of birthweight centiles. a IGF1 expression vs. birthweight centiles, b IGFBP1 expression vs. birthweight centiles, c IGFBP2 expression vs. birthweight centiles, d IGFBP3 expression vs. birthweight centiles, e IGFBP4 expression vs. birthweight centiles, f IGFBP7 expression vs. birthweight centiles. A significant positive correlation between IGF1 mRNA expression and a significant negative correlation between the binding protein expression with increasing order of birthweight centiles suggest the crucial role played by their inverse relationship in controlling fetal growth
