The results (Figure 6) showed that aberrant expression of lncRNA (high expression of NORAD, ANRIL, SNHG14, HOXA-AS2, etc., and low expression of IRAIN) was associated with a reduced RFS in AML patients (HR = 2.82, 95%CI 2.03–3.91, P < 0.001), with a statistically significant difference. The gene discussed is IRAIN; the disease is acute myeloid leukemia.
