Fig. 5: Distribution of the bone marrow quality index (BMQI) in paired first and second pull bone marrow (BM) samples and the effect of dilution of BM by peripheral blood (PB) on BMQI.

A Distribution of BMQI in paired first pull and second pull BM samples collected during the same aspiration procedure (n = 15; p < 0.001). B Distribution of the BMQI in groups of undiluted (100%) BM aspirated samples and paired samples diluted with pre-defined numbers of blood cells, containing 70% and 30% cellularity of the original BM aspirated sample (n = 12; p < 0.001 for 100% vs. 30%, p < 0.05 for 100% vs 70% and 70% vs. 30%).
