Distribution of EBV CpG sites methylation levels in NPC and nasal NKTCL samples. A The comparison of average methylation levels between NPC and nasal NKTCL nasopharyngeal brushing samples. B Methylation density plot of EBV CpG sites in NPC and nasal NKTCL nasopharyngeal brushing samples. The higher the ridge, the more CpG sites at that methylation level. C EBV genome circos plot. The inner circle was a scatter plot of methylation density of EBV sites in each nasopharyngeal brushing sample group, where different colors represented different types of cancer, and darker colors indicated higher levels of methylation
