Reviewers are required to provide written, competent and unbiased feedback in a timely manner on the scholarly merits and the scientific value of the manuscript. The reviewers assess manuscript for the compliance with the profile of the journal, the relevance of the investigated topic and applied methods, the originality and scientific relevance of information presented in the manuscript, the presentation style and scholarly apparatus. Reviewers should alert the Editor to any well-founded suspicions or the knowledge of possible violations of ethical standards by the authors. Reviewers should recognize relevant published works that have not been cited by the authors and alert the Editor to substantial similarities between a reviewed manuscript and any manuscript published or under consideration for publication elsewhere, in the event they are aware of such. Reviewers should also alert the Editor to a parallel submission of the same manuscript to another journal, in the event they are aware of such. Reviewers must not have conflict of interest with respect to the research, the authors and/or the funding sources for the research. If such conflicts exist, the reviewers must report them to the Editor without delay. Any selected reviewer who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the Editor without delay. Reviews must be conducted objectively. Personal criticism of the author is inappropriate. Reviewers should express their views clearly with supporting arguments. Any manuscripts received for review must be treated as confidential documents. Reviewers must not use unpublished materials disclosed in submitted manuscripts without the express written consent of the authors. The information and ideas presented in submitted manuscripts shall be kept confidential and must not be used for personal gain. PEER REVIEW The submitted manuscripts are subject to a peer review process. The purpose of peer review is to assist the Editor and Editorial Board in making editorial decisions and through the editorial communication with the author it may also assist the author in improving the manuscript. Unbiased, independent, critical assessment is an intrinsic part of all scholarly work, including scientific investigation. Peer reviewers are experts in their field who are not part of the editorial staff and thus are an important extension of the scientific process. Manuscripts will be reviewed by at least 2-3 reviewers. Peer reviewers are asked to submit their review within two (2) weeks. All randomized controlled trials will be fast-tracked through the peer-review and editorial process and we will endeavor to publish accepted trials within 2 weeks of final acceptance. Type of peer review is double blind. In the main review phase, the Editor sends submitted manuscripts to 2-3 reviewers experts in the field. The reviewers’ evaluation form contains a checklist in order to help reviewers cover all aspects that can decide the fate of a submission. In the final section of the evaluation form, the reviewers must include observations and suggestions aimed at improving the submitted manuscript; these are sent to authors, without the names of the reviewers. Double-blind peer review: All of the reviewers of a manuscript remain anonymous to the authors before, during and after the evaluation process and the authors remain anonymous to reviewers until the end of the review procedure. The choice of reviewers is at the discretion of the Editor-in-Chief and Editorial Board. The reviewers must be knowledgeable about the subject area of the manuscript; they must not be from the authors' own institution and they should not have recent joint publications with any of the authors. All of the reviewers of a manuscript act independently and they are not aware of each other’s identities. If the decisions of the two reviewers are not the same (accept/reject), the Editor-in-Chief and Editorial Board may assign additional reviewers. During the review process, the Editor-in-Chief and Editorial Board may require authors to provide additional information (including raw data) if they are necessary for the evaluation of the scholarly merit of the manuscript. These materials shall be kept confidential and must not be used for personal gain. The editorial team shall ensure reasonable quality control for the reviews. With respect to reviewers whose reviews are convincingly questioned by authors, special attention will be paid to ensure that the reviews are objective and high in academic standard. When there is any doubt with regard to the objectivity of the reviews or quality of the review, additional reviewers will be assigned. Members of the editorial team/board/guest editors are permitted to submit their own papers to the journal. In cases where an author is associated with the journal, they will be removed from all editorial tasks for that paper and another member of the team will be assigned responsibility for overseeing peer review.
