Fig. 5

The effect of folic acid and vitamin B12 on DNA methylation of HOX genes. Mean DNA methylation changes after a 2-year intervention with folic acid and vitamin B12 (red, n = 44) or placebo (black, n = 43) for the 1052 positions located within one of the 39 HOX (homeobox) genes located on cluster A (chromosome 7), cluster B (chromosome 17), cluster C (chromosome 12), or cluster D (chromosome 2). Only positions annotated to one of these HOX genes were depicted; intergenic regions were not included in this figure. Bars are superimposed, meaning that red (folic acid and vitamin B12) and black (placebo) bars are presented together, whenever applicable behind each other, and both reflect the actual values on the y-axis
