Among various factors, including BMI, PS, chronic GVHD (cGVHD), hemoglobin, total protein, serum albumin, and C-reactive protein, the proportion of patients with inferior PS and cGVHD was significantly skewed in the non-reintegrated group (p < 0.01; Table 2), suggesting that these two factors could directly affect social reintegration. This evidence concerns the gene ALB and chronic graft versus host disease.
