Fig. 1From: Fetal growth is associated with CpG methylation in the P2 promoter of the IGF1 geneCpG-137 methylation correlates negatively with birth length. The correlation between CpG-137 (%) and birth length (SDS) is described by the equation: Birth length = − 0.023 × [CpG-137 methylation] + 0.68 with r = 0.2 and P = 3.5 × 10−4Back to article page
