Several flaws and inconsistencies between results presented and experimental methods described were found. Specifically, instances of overlapping data within the article and with another publication authored by the same group have been found, despite the articles have different study designs. Accordingly, the editors consider the findings of this article unreliable and the conclusions to be invalid. The authors have been informed of the decision to retract the article. The corresponding author J. L. Calvo-Guirado disagrees with the decision of retraction. Co-author F. Javed agrees with the decision of retraction.
