Data are expressed as the median (range). The changes during blood transfusion were calculated by subtracting the values before transfusion from those after.
↵3-150 Values obtained before and after transfusion were compared by the Wilcoxon signed rank test.
↵3-151 p <0.05 v adult controls by Mann-Whitney U test according to Kruskal-Wallis test.
