  1. Values represent the mean of the 200 simulations. Sim. DMP %, percentage of DMPs introduced in the simulation; Diff. Means, Difference in mean methylation between groups A and B; CpGs in Bumps (%), proportion of CpGs in the modified region that are within a bump with FDR < 0.05. R 2, R2 estimate of RDA model; Target region, region that includes our simulated DMPs; Random region, region without any of the simulated DMPs
