Higher IRX1 expression was associated with a better survival rate of patients with NSCLC (p = 0.001; n = 226), and this was significantly correlated in ADC (p = 0.001; n = 226), but not with SQCC (p = 0.9; n = 190; Figure S4a). The gene discussed is IRX1; the disease is non-small cell lung carcinoma.
