3.4 Low EVI1 expression predicted poor outcomes
In the whole cohort, patients with low EVI1 expression had significantly lower 5-year RFS and OS rates than those with high EVI1 expression, respectively (RFS: 70.7% [95% CI 51.0-83.6%] vs. 87.6% [95% CI 80.8-92.1%], P =0.017, Fig. 2A; OS: 83.4% [95% CI 64.6-92.8%] vs. 95.5% [95% CI 90.3-98.0%], P =0.018, Fig. 2B).
