Fig. 1. Kaplan–Meier plot of 52 patients with atypical chronic myeloid leukemia. (A) The OS of 5 patients who progressed to AML (dotted line) was not different from that of those who did not progress to AML (solid line, N=49, P=0.6839). (B) Patients aged ≤65 years (dotted line) showed better OS than those aged >65 years (solid line, P=0.0053).
Abbreviations: AML, acute myeloid leukemia; OS, overall survival.
