Verification of the 8 methylated markers in the GEO datasets. a A hierarchical cluster heatmap shows the methylation intensity of the 8 markers in databases of PCNSL and 11 other CNS tumors downloaded from the GEO database. b The table presents the methylation characteristics and performance of each of the 8 markers to distinguish PCNSL from the 11 other CNS tumor samples. N number of samples, AUC area under the curve, CI confidence interval, P Mann–Whitney statistics, PCNSL primary central nervous system diffuse large B-cell lymphoma, CNS central nervous system
