Line graphs depicting the proportion of sites on the EPIC array (y-axis) with sufficient power (x-axis) to detect a mean difference in DNA methylation between two groups of (a) 2% and (b) 5%. The different coloured lines represent different sample sizes where the value of N the total sample size set to be a 50:50 split between groupsBack to article page
