Figure 3. Receiver operating characteristic curves of 9 validated miRNAs for diagnosis of AHF.

Receiver operating characteristic curves were performed to test the diagnostic value of 9 miRNA candidates for AHF in PCR‐discovery cohort. miR‐19b‐3p was found to have the highest discriminative potential for AHF (AUC=0.753). AHF denotes acute heart failure, AUC area under curve. Lower right annotation in each figure showed AUC with 95% CI and P value.
