The acceptance criteria for all papers are based on the quality and originality of the research and its clinical and scientific significance. Original Articles are generally reviewed at least by two peer reviewers. The Editor-in-Chief is responsible for final decisions regarding the acceptance if a peer-reviewed paper. An initial decision will normally be made within 4 weeks of receipt of a manuscript, and the reviewers’ comments are sent to the corresponding authors by E-mail. Revised manuscripts must be submitted online by the corresponding author. The corresponding author must indicate the alterations that have been made in response to the referees’ comments item by item. Failure to resubmit the revised manuscript within 12 weeks of the editorial decision is regarded as a withdrawal.
