Screening of core genes affecting the prognosis of NSCLC patients. A Forest plots based on the results of univariate Cox regression of RELA expression and other clinicopathological factors. B Forest plots are based on the results of multivariate Cox regression of RELA expression and other clinicopathological factors. HR and p-values were displayed. C RELA gene expression distribution in primary tissue and normal tissue of NSCLC tumor tissues. D RELA gene expression distribution in lymphoid tissue and normal tissue of NSCLC tumor tissues. E RELA gene expression distribution in metastatic grade and normal tissue of NSCLC tumor tissues. *p < 0.05, **p < 0.01, ***p < 0.001 and ****p < 0.0001 by Kruskal–Wallis test. F Nomogram predicting the proportion of patients with OS. G Plots depict the calibration of model in terms of agreement between predicted and observed OS. Model performance is shown by the plot, relative to the 45-degree line, which represents perfect prediction
