Author(s) should note that they can withdraw their articles before being sent for peer review or when they are returned to them for making changes (minor or major revisions required), and not when they are under peer review. Unless that round of peer review (and not the total duration) for the article has exceeded the maximum duration of the peer review process stated on the website (6 weeks).
Articles can only be withdrawn before their acceptance, except in cases that contain errors or have been accidentally submitted twice. Occasionally, articles may represent infringements of professional ethical codes, such as multiple submission, bogus claims of authorship, plagiarism, fraudulent use of data, or the like.
Articles that include errors, or are duplicates of or very similar to other published article(s) or are determined to violate the journals’ publishing ethics guidelines in the view of the editors, may be withdrawn.
For this purpose, a withdrawal letter must be emailed to the editorial office indicating the decision to withdraw and explaining the reason for withdrawal signed the corresponding author and the submitting individuals’ signature.
