Fig. 2From: Alterations in DNA methylation associate with reduced migraine and headache days after medication withdrawal treatment in chronic migraine patients: a longitudinal studyManhattan plot from the epigenome‐wide association study. Manhattan plot showing the –log10(p value) for each CpG site associated with changes in DNA methylation in monthly headache days (MHD) responders versus non-responders. The threshold for epigenome-wide significant association (p < 9.42 × 10–8) is indicated by a solid black line. The threshold for epigenome-wide suggestive association (p < 5 × 10–5) is indicated by a dashed black lineBack to article page
