RNPC3 and non-small cell lung carcinoma: To further verify the accuracy of these differential genes as diagnostic genes for non-small cell lung cancer, ROC curve analysis of the above these genes was applied and found that RNPC3 (AUC: 0.856, 95% CI: 0.820–0.889), and RHEBL1 (AUC: 0.863, 95% CI: 0.834–0.890) all had AUCs greater than 0.8 (Figures 4E,F).
