The above article, published online on 28 December 2023 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the authors; the journal Editor-in-Chief, Hiroaki Kajiyama; and John Wiley & Sons, Australia, Ltd. The retraction has been agreed upon following an investigation into concerns raised by a third party, which revealed major conceptual overlap and significant primary data redundancy with a previously published article by an overlapping group of authors. Such publishing practice is against the journal's policy and Wiley's Best Practice Guidelines on Research Integrity and Publishing Ethics.
