Figure 1 from Plasma Cell-Free Human Papillomavirus DNA and Oral Gargle HPV DNA in Patients with HPV-Related Oropharyngeal Cancer Treated with Radiotherapy

Waterfall plot showing the % change of week 4 TTV compared with baseline for all patients who met the inclusion criteria (N = 50). Each legend at the bottom of the waterfall plot show the status of HPV DNA clearance for oral gargle at weekly intervals for weeks 1 to 4 and for plasma at week 4; baseline HPV DNA status by plasma and oral gargle; and the locoregional disease-free survival (LRFS), distant metastatic disease-free survival (DMFS) recurrence, and PFS statuses at 24 months after treatment of individual patients.
