aGVHD, acute GVHD; BM, bone marrow; cGVHD, chronic GVHD; CsA, cyclosporine A; mod-severe cGVHD, moderate-to-severe cGVHD; MPA, mycophenolic acid; IS-requiring cGVHD, chronic GVHD requiring systemic immunosuppressive treatment.
P < .05, significantly different for the comparison between the PTCY arm and the control arm (TAC/MTX, CsA/MPA, or TAC based).
