Overall survival curves of patients with AML, according to nm23-H1 level and WBC count.

(A) Patients with high nm23-H1 levels (≥ 80 ng/mL; n = 29) had a worse prognosis than those with low nm23-H1 levels (< 80 ng/mL; n = 73). (B) Patients with a high WBC count (> 50 000/μL; n = 11) had a worse prognosis than those with a low WBC count (≤ 50 000/μL; n = 91).
