Kaplan–Meier curves of overall survival and first progression in non-small-cell lung cancers were generated by in silico meta-analysis to reveal a positive correlation between ATF5 expression and poor prognosis in non-small-cell lung cancer and lung adenocarcinoma (Figure 6A, 6B, 6C, 6D). This evidence concerns the gene ATF5 and non-small cell lung carcinoma.
