Overview of the meta-analysis results with a P value <1.0 × 10−6 after correction for inflation/bias with the bacon R package. The used rlm with robust SEs was as follows: β value ˜ glycemic trait + GA at maternal sampling + sex of the child + imputed cord blood cell proportions + maternal age + GA at birth + parity and cohort-specific (technical) variables.
P value after correction for inflation and bias with the bacon R package. Correction is based on the entire distribution of test statistics of each meta-analysis and may therefore (slightly) differ between the fasted and combined meta-analyses as the sample size is increased for many CpGs.
