Patient demographic characteristics distribution among groups based on anti-HLA antibodies, DSA and MICA detection status.

Abbreviations: AHA : anti-HLA antibodies;ALL: acute lymphoblastic leukemia; AML: acute myeloid leukemia; ATG:anti-thymocyte globulin; Bu: busulfan; Cy: cyclophosphamide; DSA : Donor-specific anti-HLA antibody; Flu: fludarabine; MDS: myelodisplastic syndrome; Mel: melphalan; MICA : major-histocompatibility-complex class I–related chain A antigens MM: mismatch; MRD: matched related donor; MTX: methotrexate;MUD: matched unrelated donor; VP16:etoposide. AHA of either classes were detected in 31 patients. Class I AHA and class 2 AHA alone were detected in 9 patients, and both in 13 patients, thus 22 (9+13) patients were positive for class I AHA and class II AHA. MICA antibody data was available for only 62 patients out of 70. Data for infused number of CD34+ cells was available for only 64 patients out of 70.
