Fig. 2: Discriminatory ability of the bone marrow (BM)-associated variables evaluated as hemodilution markers of BM sample pull.

Fig. 2

The figure depicts receiver-operating characteristic (ROC) curves for B cell precursors (in green), myeloid precursors (in blue), nucleated red cells (in red), mast cells (in yellow), BM sample white blood cell (WBC) count (in black), and bone marrow quality index (BMQI) (in violet) for discrimination between first and second pull BM aspirated samples. Sample sizes were n = 219 for first pull and n = 132 for second pull for cell populations and BMQI, and n = 215 for first pull and n = 121 for second pull for the WBC count. The table below the figures shows area under the curve (AUC) values with 90% confidence intervals (CI) for each ROC curve in the figure along with p-values indicating statistical significance of differences observed between ROC curves.
