Comparison of soluble human leucocyte antigen-G (sHLA-G) plasma level between the first month (days 0–30) and the third month post allograft (days 60–90) in patients without acute graft-versus-host disease (n = 6). A significant increase of sHLA-G level is found in the third month post allograft [Wilcoxon's matched-pairs test: P < 0·05 (*)].
