Supplementary Figure 2 from Plasma Cell-Free Human Papillomavirus DNA and Oral Gargle HPV DNA in Patients with HPV-Related Oropharyngeal Cancer Treated with Radiotherapy

Supplemental Figure 2: Association of Baseline Clinical Characteristics with Plasma and Oral Gargle HPV DNA Status. Bar charts show the comparison of proportions of patients with A) detectable versus undetectable baseline plasma cfHPV DNA or B) detectable versus undetectable baseline oral gargle HPV DNA stratified by key baseline clinical variable groups. P-values represent Fisher’s Exact Tests where p < 0.05 is considered significant.
