Using a cutoff ratio of 0.04, which was the first quartile value (Q1) of the AIMP2-DX2/AIMP2 expression ratio in AML, a Kaplan–Meier curve for the overall survival (OS) showed that patients with an AIMP2-DX2/AIMP2 expression ratio ≥Q1 tended to exhibit poor OS (median survival 47.7 months) compared to those with an AIMP2-DX2/AIMP2 expression ratio <Q1 (median survival not reached; log-rank P = 0.25; Fig. 3a). This evidence concerns the gene AIMP2 and acute myeloid leukemia.
