a Time course of the ctDNA fraction in the indicated cases who experienced recurrence (recurrent cases) or did not (non-recurrent cases). The x-axes in the recurrent cases and non-recurrent cases represent the days before the date of recurrence detection by computed tomography (CT) scans and the latest collection of cfDNA, respectively. Kaplan–Meier curves for b recurrence-free survival and c overall survival according to positive and negative ctDNA samples after radical cystectomy.
