Overview of species covered by previously published datasets and the distribution of GBM levels in each. X-axes for histograms show percent methylation (summed across all CpG sites within the gene and averaged across all samples from each study) on the log₂ scale. The Y-axes show the counts of genes. Text reports the species, reference, NCBI Bioproject accession, the treatment groups compared here, the Whole Genome Bisulfite sample size (with mean genomic coverage), and the RNA-seq sample size for each study
