Manhattan plot of the Factor A EWAS. The x-axis depicts chromosomes and the location of each CpG site across the genome. The y-axis is the -log10 of the p value for the association with levels of Factor A Simoa markers defined by Aβ40 and Aβ42. Each dot represents a CpG site. The red line indicates the level for epigenome‐wide statistical significance (p = 1 × 10–7) and the blue line the level for suggestive significance (p = 1 × 10–5). The EWAS-significant locus is highlighted in green
