There is a 30% discount for articles where the corresponding author is a British Society of Gastroenterology member and a 25% discount is available where the corresponding author has reviewed for BMJ Open Gastroenterology within the previous 12 months. These discounts cannot be combined.

Articles submitted to BMJ Open Gastroenterology are subject to peer review.

BMJ requests that all reviewers adhere to a set of basic principles and standards during the peer-review process in research publication; these are based on the COPE Ethical Guidelines for Peer Reviewers. Please refer to our peer review terms and conditions policy page.
BMJ is committed to transparency. Every article we publish includes a description of its provenance (commissioned or not commissioned) and whether it was internally or externally peer reviewed.
Plagiarism is the appropriation of the language, ideas or thoughts of another without crediting their true source and representation of them as one’s own original work. BMJ is a member of CrossCheck by CrossRef and iThenticate. iThenticate is a plagiarism screening service that verifies the originality of content submitted before publication. BMJ runs manuscripts through iThenticate during the peer review process. Authors, researchers and freelancers can also use iThenticate to screen their work before submission by visiting www.ithenticate.com.
