Statistically significant differentially methylated regions (DMRs) (Sidak P value < 0.05) for exclusive breastfeeding duration

Age	Location	No. of probes	Slk P value	Sidak P value	Ref gene name and genomic feature		CpG feature
18	chr1:173837002-173837197	7	4.13E−12	9.62E−09	GAS5	Body; TSS150;TSS200	Island, shore
18	chr2:24397787-24397845	3	1.43E−07	0.001	FAM228A	TSS200	Island

Both Slk = uncorrected Stouffer-Liptak-Kechris P values, and Sidak P values corrected for multiple testing are reported. Here, 5′UTR = 5 prime untranslated region; TSS200 = 0–200 bases upstream from the transcription start sites; TSS1500 = 200–1500 bases upstream from the transcriptional start site; body = gene body
