Fig. 6: Mutation landscape of pre-treatment oral rinse-derived ctDNA.

A Overview of oral rinse-derived ctDNA status, clinical characteristics, and 1-year recurrence at baseline. B, C Kaplan–Meier estimates of PFS (B) and OS (C) according to pre-treatment oral rinse-derived ctDNA status. ctDNA circulating tumour DNA, PFS progression-free survival, OS overall survival.
