In patients with LUAD, the decreased expression of EMID1 was significantly correlated with clinical stage (stage III vs. stage I, P=0.012; stage IV vs. stage I, P=0.009), tumor status (T3 vs. T1, P=0.041), lymph node (N2 vs. N0, P=0.007), and distant metastasis (M1 vs. M0, P=0.030). The gene discussed is EMID1; the disease is neoplasm.
