Figure 3From: The causal effect of red blood cell folate on genome-wide methylation in cord blood: a Mendelian randomization approachThe observed correlation (blue line) of the associations between methylation and log RBC folate levels, for the 16,989 loci estimated using the Mendelian Randomization and standard ordinary least squares methods. Methylation level was square-root arcsine transformed to stabilize the variance. Models adjusted for conception intention.Back to article page
