Factors significantly associated with OS were HSC source, diagnosis, GVHD prophylaxis, and levels of both TIM-3 and sIL2-Rα above their respective cutoff values (HSC source: p to remove, p = 0.003; diagnosis: p to remove, p = 0.01; GVHD prophylaxis other than CSA + MTX + ATG: p to remove, p = 0.002; TIM-3 over the threshold: p to remove, p = 0.001; sIL2-Rα over the threshold: p to remove, p = 0.008). This evidence concerns the gene HAVCR2 and graft versus host disease.
