Fig. 3From: Superior GVHD-free, relapse-free survival for G-BM to G-PBSC grafts is associated with higher MDSCs content in allografting for patients with acute leukemiaBox plots showing the absolute number of infused MDSCs with respect to II–IV aGVHD (a) and extensive cGVHD (b). Bars represent the median values, whereas whiskers represent the minimum and maximum. The severity of aGVHD (c) and cGVHD (d) were plotted against the number of infused MDSCs. The grade for severity of cGVHD included limited and extensive cGVHD (1 = limited, 2 = extensive, respectively). r and P values were calculated using Spearman’s correlation testBack to article page
