(a) ROC curve analysis for the accuracy of the association between upregulation of miR-133a and COVID-19 infection. (b) ROC curve analysis for the accuracy of the association between downregulation of miR-146a and COVID-19 infection. AUC, Area under the curve. *AUC (0.9–1) = excellent discriminating efficiency, **AUC (0.7–0.8) = fair discriminating efficiency. *Significant level at P value < 0.05.
