Following a journal-wide investigation, it was identified that some cited references in this article are inappropriate to support the statements associated with them, or were used to support claims without referring to the primary sources that substantiate those claims. This indicates a lack of recognition and use of the broader relevant literature by the authors, which does not meet the journal's academic and ethical standards.
