Total yields of TNCs, CD34⁺cells, CFCs, and LTC-ICs. Box plots of total yields of total nucleated cells (TNCs; A), CD34⁺ cells (B), CFCs (C), and LTC-ICs (D) in poor mobilizers receiving rhG-CSF (n = 8) or rhGH/rhG-CSF (n = 15). The boxes extend from the 25th percentile to the 75th percentile, the lines indicate the median values, and the whiskers indicate the range of values. Statistical difference was evaluated using the Wilcoxon matched pairs test (2-tail). P values are shown in the panels.
