Distribution of EBV CpG sites methylation levels in four tumor tissue samples. A Box plots of the average methylation density of CpG sites annotated on different phases genes. B Methylation density plot of EBV CpG sites in NPC, EBVaGC, lung LELC and parotid LELC tissue 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 tumor tissue, where different colors represented different types of cancer, and darker colors indicated higher levels of methylation
