Table 4 Adjusted associations for methylation levels of the 9-CpGs in the DMR of the PON1 gene in cord-blood of males with cognitive test scores measured during early childhood. Estimated change in cognitive test scores per 10% increase in methylation of each CpG and mean methylation levels of the PON1 region.
