Fig. 3: Kaplan–Meier analysis of EFS and DRFS stratified by ctDNA detection status at different timepoints in TNBC patients.

EFS (A) and DRFS (B) of 122 patients grouped by baseline ctDNA status. EFS (C) and DRFS (D) of 113 patients grouped by post-NAC (pre-surgery) ctDNA status. EFS (E) and DRFS (F) of 118 patients grouped by post-surgery ctDNA status. Survival analyses were performed using the Kaplan–Meier method. p values were calculated using the log-rank test. Hazard ratios (HR) and the corresponding confidence intervals (CI) were calculated using the Cox regression models. EFS event-free survival, DRFS distant recurrence-free survival.
