Nutritional status significantly impacts outcomes in allogeneic hematopoietic stem cell transplantation (allo-HSCT). Among various indices, the Risk Index (NRI), Prognostic (PNI), and Controlling Status (CONUT) scores hold potential as prognostic tools. This study compares their predictive utility for transplant outcomes. A retrospective analysis was conducted on 41 patients who underwent first allo-HSCT between October 2022 July 2024. were calculated using pre-transplant data, associations...
