FIGURE 5.

Diagnostic value of microRNAs (miRNAs) for dilated cardiomyopathy and unexplained heart failure presented in receiver operating characteristic curves with area under the curve (AUC) compared with each other. As receiver operating characteristic curve illustrates the diagnostic ability of a binary classifier system as its discrimination threshold is varied, it is created by plotting the true positive rate (sensitivity) against the false positive rate (1‐specificity). AUC is equal to the probability that a classifier will rank a randomly chosen positive instance higher than a randomly chosen negative one. (A–E) Heart failure patients against healthy donors; (F, G) dilated cardiomyopathy patients against the rest.
