Review process
Manuscripts submitted to the Editorial Office are assessed by reviewers.The rules of review are in conformity with the guidelines of the Ministry of Science and Higher Education (www.nauka.gov.pl).
The Clinical and Experimental Hepatology has always used a double-blinded peer review process. The Editorial Office verifies that the submitted manuscript complies with the journal’s formal requirements and its profile. If the manuscript evidently does not match the profile of the journal, or if it fails to comply with the basic formal requirements, it is rejected at this stage. Manuscripts that receive positive in-house reviews are followed by peer review by at least two reviewers.
The Editorial Office chooses the reviewers based on the subject of the submitted manuscript. The competences of a reviewer are confirmed by the academic achievements. The reviewer is independent of the author of the reviewed manuscript and the Editorial Office of the journal.
An invited reviewer has 7 days to accept or decline the invitation to review. In the review process following qualities are evaluated: the novelty of the manuscript, importance of obtained results, methods, statistical analysis and data quality, the presentation of results, the quality of discussion and appropriate selection of the literature. Evaluation takes place in the points system, using a special form of reviews, which is available only to the Editors. Besides, the review should include: conclusion on the overall assessment of the manuscript (accept without change, accept after minimal changes, rate manuscript once again after major changes or reject), and final remarks.
The process of evaluation will not take more than 21 days. The recommendations of the reviewers are presented to the author in writing. The review procedure respects the principle of confidentiality.
The Editorial Office reserves the right to reduce manuscripts and to make language corrections without consulting the author. Other changes are consulted with the authors.

Proofs
Authors will receive a proof from an Assistant Editor. That proof should be corrected and returned within 48 hours, preferably by e-mail or fax. If the Publisher receives no response from the authors after 7 days, it will be assumed that there are no errors to correct and the article will be published.
