Assessing the yield and safety of endoscopy in acute graft-vs-host disease after hematopoietic stem cell transplant

¹Thrombocytopenia was defined as a pre-procedure platelet count ≤ 50 × 10³/µL or ≤ 75 × 10³/µL and ≥ 1 units of platelet transfused. Neutropenia was defined as a pre-procedure absolute neutrophil count < 1000 cells/µL.

²P = 1.000 for thrombocytopenic vs non-thrombocytopenic patients and P = 0.425 for neutropenic vs non-neutropenic patients.
