Several factors showed a significant association with OS by univariate analysis, including recipient age (<50 or >50 years; p = 0.013), reduced LDH levels at the MRR (p = 0.020), increased Hb levels at the MRR (p = 0.046), creatinine at the first re-evaluation (p = 0.044) and MRR (p = 0.002), disease type (AML vs. other; p = 0.046), hypertension (p = 0.030), and the presence of metabolic comorbidities (p = 0.004) (Figure 2B–D). This evidence concerns the gene GSTM1 and acute myeloid leukemia.
