Kaplan-Meier estimate of probability of DFS according to PCR status of harvests and molecular follow-up.

(A) DFS for patients whose harvests were PCR⁻ (n = 20, solid line) versus patients whose harvests were PCR⁺(n = 22, dotted line); P < .01. (B) DFS for patients achieving a molecular remission (n = 24, solid line) versus patients with PCR⁺ follow-up (n = 13, dotted line);P < .001.
