¹The β from a linear mixed model corrected for the correlation between individual CpG dinucleotides, bisulfite batch and sex. The investigated variable was entered as a fixed effect.

²A two-sided p value resulting from a linear mixed model corrected for the correlation between individual CpG dinucleotides, bisulfite batch and sex.
