*2.4. Evaluation of Prediction Performance of Models in The Cancer Genome Atlas (TCGA) Lung Cancer*

Prediction performance of selected models was further tested using 899 TCGA lung cancers, including 75 normal and 824 tumor tissues. The performance was tested without distinction between adenocarcinoma and squamous cell carcinoma. The prediction performance of models was evaluated using receiver operating characteristic (ROC) curves, plotted using the MedCalc statistical Software version 19.0.5 (MedCalc Softward bvba, Ostend, Belgium).
