Figure 2

A bar graph of the incidence of episomal and integrated HPV in head and neck cancer over year of birth for patients. A trend in the incidence for patients with episomal and integrated HPV is shown based on when the patients were born. Integrated HPV is shown by orange (dark) and episomal HPV is shown by blue (light). The data is shown for five-year intervals. The incidence is calculated based on the total for each interval. The sample size is shown for each interval. There are 4 patients born before 1914 and 2 patients born after 1983 with no HPV and not shown in this plot.
