ROC analysis showed that the AUC for the prediction of CHAF1A mRNA expression in EBV infection were 0.728 (sensitivity:0.611; specificity:0.782), 0.885 (sensitivity:1.000; specificity:0.675), and 0.788 (sensitivity:0.815; specificity:0.689) in the three cohorts, respectively (Fig. 2B). Here, CHAF1A is linked to Epstein-Barr virus infection.
