Further, via ROC curves of the 240 samples based on SMOTE method, the constitutive genes (CCL2, CCL7, HS3ST1, MRVI1, TM4SF1, and TPST1) and risk score of m7GPS demonstrated conspicuous accuracy in distinguishing IPF patients and healthy individuals (AUC > 0.843, Figure 6). This evidence concerns the gene IRAG1 and idiopathic pulmonary fibrosis.
