Relationship between bone marrow and PB blast percentage measured by MFC in patients with AML. PB and BMA blast percentage measured by MFC are plotted for all sample pairs (A; N = 724), first sample pair for each patient (B; n = 477), pairs for which PB and BMA samples were obtained on the same day (C; n = 323), pairs obtained from patients within 30 days before HCT (D; n = 32), pairs obtained within 90 days after HCT (E; n = 64), and pairs for which BMA blasts were <5% by both flow cytometry and morphology (F; n = 209). Spearman correlation coefficient and linear regression correlation coefficient are shown for each analysis.
