Results: A total of 12 articles were included, including 1 clinical decision, 4 guidelines, 1 evidence summary, 1 expert consensus, 3 systematic reviews, 1 cohort study, 1 expert opinion,. A total of 14 best evidences were summarized from 4 aspects, including scientific diet and tolerance assessment, nutrient selection, nutritional support method selection, and multidisciplinary cooperation. Conclusions: This study systematically integrates the relevant evidence of nutritional support in patients with acute gastrointestinal graft-versus-host disease, and can provide evidence-based evidence for nutritional support in patients with acute gastrointestinal graft-versus-host disease.
