Graft‐versus‐host disease (GvHD) is a serious complication of allogeneic haematopoietic stem cell transplantation (HSCT). Both anti‐thymocyte globulin (ATG) and post‐transplant cyclophosphamide (PTCy) are used as lymphocyte‐depleting strategies, yet a systematic comparison of transplantation outcomes between these two methods in matched unrelated donors (MUD) transplantations with non‐myeloablative conditioning (NMC) is lacking. Adult patients with haematological malignancies who had undergone MUD HSCT with NMC regimens between 2014 and 2021 at 2 centres in Amsterdam (ATG: n = 95, PTCy: n = 90), were included in this retrospective study. Patient characteristics were comparable between the groups. The cumulative incidence of acute GvHD grade II–IV was 48% in the ATG group compared to 21% in the PTCy group (p < 0.001). The 3‐year moderate/severe chronic GvHD was …
