In the article titled “Circulating MicroRNAs as Novel Potential Biomarkers for Left Ventricular Remodeling in Postinfarction Heart Failure” [1], a duplication of the panels in Figure 7(b) was noted on PubPeer [2].

The authors have re-examined the data and explained that the error occurred due to the incorrect use of the ROC curve drawing software (MedCale). The authors provided the corrected ROC curve graphs and the underlying data. The corrected Figure 7(b) is shown below:


Figure 7 
Expression of candidate plasma miRNAs in the patient population. (a) The expression levels of plasma miR-20a-5p, miR-340-5p, and let-7i-5p in patients with postinfarction HF () and control patients with stable angina and without significant coronary lesions and HF (). (b) ROC curves and the AUCs of miR-20a-5p, miR-340-5p, and let-7i-5p. versus patients with stable angina and without significant coronary lesions and HF. HF: heart failure; ROC: receiver operator characteristic; AUC: area under the curve.
