Moreover, the ROC curves were used to evaluate the predictive prognostic power of different indexes, and the results suggested that NRI, SIRI, ALI, LMR, NLR, PNI, and SII could significantly predict OS in NSCLC patients receiving EGFR-TKI therapy (P < 0.05), other than CONUT and PLR (P > 0.05) (Figure S4A–I). This evidence concerns the gene EGFR and non-small cell lung carcinoma.
