Fig. 4: PFS by C4D15 ctDNA MRD status.

Data are presented as Kaplan–Meier curves, with tick marks indicating patients with censored data (n = 63 ctDNA-evaluable patients; n = 20 with cleared MRD at C4D15, n = 43 with detected MRD at C4D15). Median values with 95% CIs are presented alongside the respective curves. The HR for PFS in patients with MRD cleared versus MRD detected was calculated by univariate Cox regression.
