Mean percentage of positive cells in each cell category according to the cytogenetic/molecular groups.

Cell categories are noted in Figure 1, and the mean of positive cells is given as plus or minus the SD. A total of 100 blasts were analyzed for each case, assigned to categories 1-12, and then recounted and reassigned to category 13 or 14. Category 15 was defined by Pelger-like maturing cells whose percentage was evaluated on the total cells, including blasts, from the granulocytic lineage (n = 100).
