DNA methylation levels in different groups.

<p>Analysis of sample DNA methylation mean β values for all probes, TSS200 probes, TSS1500 probes, 1<sup>st</sup> Exon probes, Gene Body probes, 3′UTR probes, and 5′UTR probes. Atypical and malignant meningiomas tend to have decreased levels of global DNA methylation in comparison to benign meningiomas.</p>
