  1. *Difference in mean DNA methylation level between cases and controls. †Adjusting for a total of 815,017 CpG sites using the false discovery rate (FDR) method. ‡Multiple testing was corrected by FDR. One probe (cg24891539) failed to be confirmed by targeted bisulfite sequencing in the internal validation cohort
