Fig. 4From: Blood RNA-Seq profiling reveals a set of circular RNAs differentially expressed in frail individualsROC curves showing the potential circRNAs to be biomarkers in frailty. A A ROC curve for each of the four validated circRNAs is represented. B, C and D plots represent the ROC curves obtained by combining different circRNAs. Their corresponding AUC values for each of the curves are shown in the lower right cornerBack to article page
