TNFRSF9 and non-small cell lung carcinoma: On this basis, a forest plot was constructed as shown in Figure 3A. Following that, a predictive model of NSCLC prognosis was developed with least absolute shrinkage and selection operator Cox regression and 4 CRICGs, namely CD209, TNFRSF9, SIRPA, and HLA-DMB (see Fig. 3B).
