Furthermore, survival analysis stratified by cancer type revealed that there was a significant association between the frequency of Nrf2-activating MU and shorter OS only in small cell lung cancer (HR: 18.81, 95% CI 2.48–142.46; Fig. 3D) and NSCLC (HR: 1.56, 95% CI 1.19–2.03). The gene discussed is NFE2L2; the disease is cancer.
