Survival analysis using KM-plotter for the JetSet probe set alone and best cut-off option for all available datasets combined, revealed that elevated CD40 gene expression was correlated with improved five-year OS of NSCLC patients (n = 1926) with squamous cell carcinomas and adenocarcinomas (Figure 3a–c, p = 0.002 and p = 0.019, respectively). Here, CD40 is linked to squamous cell carcinoma.
