GSTM1 and anemia: 6, who, using a multivariate analysis in the same cohort, found that transfusion dependence, anemia, thrombocytopenia, cytogenetic status, and age were all significant predictors of survival. Our subgroup analysis revealed that both OS and non‐leukemic death rates were significantly improved in TI patients, regardless of Hb level, compared with TD patients. Other studies have demonstrated that transfusion dependence or transfusion intensity can negatively impact OS in patients with MDS 10, 12, 23, 24.
