DNA methylation analysis in HPV16-negative OPSCC patients. a Pie chart showing the percentage of differentially methylated CpG in promoter, gene body, and intergenic regions. b Box plot showing the average methylation level (beta-value) of all CpG differentially methylated in not relapsed (NR) vs relapsed (R) HPV16-negative OPSCC patients. c Histogram showing the molecular function where the genes showing differentially methylated promoter are involved
