Results are shown at each of the 28 CpGs located in CYP2E1, between participants with (n = 96) and without (n = 474) acetaminophen detection, sorted by P-value

DNAm DNA methylation, FDR false discovery rate, chr chromosome. The P-values are the original P-values before adjustment for multiple testing. CpG sites with P-value < 1.79 × 10⁻³ (Bonferroni corrected threshold) were marked with asteroid (*). CpG sites with FDR < 0.05 were bolded. Covariates are child sex, delivery type, parity, gestational age, birthweight, maternal age, maternal marital status, prenatal smoking, prenatal alcohol use, intrauterine inflammation, preeclampsia, diabetes mellitus, maternal stress, estimated cell types and 2 surrogate variables. ^aGene feature category of CpG sites obtained from UCSC database: TSS, transcription start site; TSS200, 200 bases from TSS; TSS1500, 1500 bases from TSS; UTR, untranslated region
