NKX2-1 and neoplasm: The Kaplan‐Meier analysis revealed that patients with high expression of NKX2‐1‐AS1 in tumor tissues exhibited significantly shorter 5‐year OS (40.52% vs. 58.89%, P = 0.0051) and 5‐year PFS (36.67% vs. 59.93%, P = 0.0019), than patients with low NKX‐2‐1AS1 expression (Fig. 2F,G).
