Easy Submission Process
For New submissions, we do not require the authors to submit their manuscript in separate files.

Only when the paper is at the acceptance stage, the journal assistant will ask the author to submit/send the manuscript file in their correct format needed for publication.
Critical Comments in Biomedicine (CCB) is an electronic international peer-reviewed journal published semiannually by Shahid Sadoughi University of Medical Sciences. The journal is specialized in the publication of review articles (including narrative reviews, systematic reviews, systematic reviews and meta-analyses, overviews of systematic reviews, mini-reviews), commentaries, letters to editors, and systematic review protocols written in the field of biomedicine. The journal particularly welcomes the review articles with null findings and the updated reviews.
Although several reporting guidelines and checklists are developed to improve the reporting of systematic reviews and meta-analyses, and the majority of systematic reviews are now registered, they do not guarantee the quality of the published work and their cautious evaluation is still needed. This is while the systematic reviews and meta-Systematic reviews and meta-analyses published in the field of medicine are considered as the top-level evidence by researchers, professionals, and even politicians. Therefore, low-quality reviews might be misleading.
Our team believes that professional journals like CCB might better evaluate such articles by gathering the experts interested in the field, which makes the published evidence more reliable. The journal is dedicated to publishing review articles, only considering their quality without taking the manuscripts’ readership, their results, and the possibility of getting citations into account.
All authors should have the following criteria: (1) Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND (2) Drafting the work or revising it critically for important intellectual content; AND (3) Final approval of the version to be published; AND (4) Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.
Changes in author list
It is expected that authors carefully consider the list and order of authors before submission and provide the list of authors at submission. Any change (addition, deletion, or rearrangement of author names) in the authors’ list should be requested only before acceptance and only if approved by the journal Editor. The authors should provide a letter explaining the reason for the change in the authors’ list and that all authors agree with the change signed by all authors (the added or removed author should also sign the letter). The editor may accept the change in the authors’ list after acceptance or publication in exceptional circumstances.
