ROC curve analysis of microRNAs. a–c ROC curve analysis of miR-155, miR-10b and miR-23a showed high sensitivity and specificity in discriminating disease group (HCM, DCM) with AUC ranged from 0.925 to 0.933. d ROC curve analysis of miR-21 showed AUC was notably reaching 0.944 which could distinguish DCM from Control. e–f ROC curve analysis of miR-27a and miR-1-3p showed high sensitivity and specificity in discriminating HCM from Control. Area under the curve (AUC) > 0.7 was considered accepted. HCM hypertrophic cardiomyopathy; DCM dilated cardiomyopathy
