The median NR2F1-AS1 expression in NSCLC tissues was defined as the cut-off value, and all the 73 patients with NSCLC were accordingly classified into either low NR2F1-AS1 (n = 36) or high NR2F1-AS1 (n = 37) expression groups. The gene discussed is NR2F1; the disease is non-small cell lung carcinoma.
