1. Why has the BMJ Group created BMJ Open?

BMJ Open offers authors an affordable publishing service so that they can share their medical research from any therapeutic area or discipline. The journal aims to ensure that any well-conducted study has a home where it can be fully reported.

We particularly hope that BMJ Open will attract work that deserves publication but does not quite meet the specific needs of the audiences of the BMJ and the BMJ Group's specialist journals, which is why the journal will welcome both high and lower impact studies.

Transparency and openness define BMJ Open. All articles will follow the BMJ Group high standards of ethics and transparency and will include clear statements of studies' strengths and limitations. As well as publishing definitive articles we will encourage researchers to share as much additional knowledge as possible. We welcome submissions of study protocols and pilot studies and will make it easy for authors to share raw datasets either as additional electronic material or through direct linkage from BMJ Open articles to data repositories.

2. What type of articles does BMJ Open publish?

We welcome research articles reporting a wide range of study designs, including:

• Study pre-protocol
• Study protocol
• Pilot study
• Qualitative study
• Cross sectional study or survey
• Before & after study
• Case control study
• Cohort study
• Diagnostic test study
• Modelling study
• Economic evaluation
• Randomised controlled trial
• Systematic review or meta-analysis
• Secondary analysis of database(s)

The journal will also publish e-letters that respond directly to issues raised in BMJ Open articles. See our resources for authors and instructions for authors pages for more information.

3. How do I submit my article?

Please submit using our online manuscript submission site. If your article was previously submitted to another BMJ Group journal and was rejected, we will happily assist in transferring the files to the BMJ Open site if you would like to be considered by BMJ Open. Please email the editorial office at editorial.bmjopen{at}bmjgroup.com for help with this (the article must not be under consideration by any other journal).

4. Can I opt for my article to be considered automatically for BMJ Open if it is not accepted by the BMJ or another BMJ Group journal?

Until the BMJ and the group's other journals have migrated to Scholar One Manuscripts submission sites, automatic transfer of papers is not possible. Please email the editorial office (editorial.bmjopen{at}bmjgroup.com) with the manuscript number of your original submission and we will gladly assist with the transfer of files.

5. What overall format should articles follow?

Please structure your research article using the items listed in the appropriate reporting statement, such as:

• CONSORT for a randomised controlled trial (CONSORT has several extension statements, e.g. for cluster RCTs, pragmatic trials)
• PRISMA for a systematic review or meta-analysis of randomised trials
• MOOSE for a systematic review or meta-analysis of observational studies
• STARD for a study of diagnostic accuracy
• STROBE for an observational study

The EQUATOR (Enhancing the QUality and Transparency Of health Research) online library includes a wide range of reporting statements at http://www.equator-network.org/resource-centre/library-of-health-research-reporting/.

6. How can I share the raw data or other additional data from my study when it is published in BMJ Open?

Like the BMJ, we will ask authors to include a data sharing statement at submission. The statement should explain which additional unpublished data from the study-if any-are available, to whom, and how. Those data could range from additional explanatory material to the complete dataset. People allowed access to the data might range from fellow researchers to everyone. And data might be available only on request, accessible online with a password, or openly accessible to all on the web with a link on bmjopen.com.

BMJ Open is committed to playing a role in encouraging greater sharing of data. We encourage authors to link their BMJ Openarticles to all data deposited elsewhere. We ask this largely because we are keen to maximise the usefulness and usage of data and promote transparency, but also because many research funders now encourage or even mandate data sharing. We understand that many authors wish to guard data until they have published all their own papers, and we know that data sharing is hard to do. But we hope that authors will, increasingly, set the data free, perhaps after a set period of personal use.

We are working with the UK Dryad repository to provide a simple way for authors to store data and link to it from the published article. Please contact the editorial office if you are interested in pursuing this option.

We also strongly support the view that researchers should seek informed consent to data sharing from research participants upfront, at the recruitment stage. This editorial in the BMJ provides some advice on how to go about this. There are good ethical and practical reasons for doing so. Even if the investigators have no current plans to share raw data, at some future time data sharing may become the norm. If so, sharing will be much easier if no one has to try to seek consent retrospectively.

Consent is particularly important because participants may be identifiable in a dataset - even an "anonymised" one that does not contain names or addresses. The combination of three or more indirect identifiers such as age, sex, and an unusual clinical detail may be enough for at least the participant, or another interested party, to recognise themselves.

Therefore, please provide a data sharing statement such as: "Technical appendix, statistical code, and dataset available from the corresponding author at <email address or url>. Participants gave informed consent for data sharing [or ...consent was not obtained but the presented data are anonymised and risk of identification is low... or consent was not obtained but the potential benefits of sharing these data outweigh the potential harms because...]"
If there are no such further data available, please use this wording: "No additional data available".

7. How quickly will I know the decision on my article?

BMJ Open will provide authors with a rapid and open peer review service, providing the majority of first decisions within four weeks.

8. How are articles peer reviewed?

BMJ Open will use open peer review. Reviewers will sign their reports and will declare competing interests to editors, and reviewers' reports will be posted online alongside accepted articles.

9. What article processing fee will BMJ Open charge?

Authors will be charged £1200 ( inclusive of VAT where applicable) for publication. This will apply to accepted articles and there are no submission, colour or page charges. Submitted papers will be judged entirely on scientific validity rather than ability to pay.

We appreciate that some authors do not have access to funding to cover publication costs. The journal will accept part payment where only limited funds are available, and offers a waiver to authors without funding. No payment information is requested before an article is accepted, so the ability to pay cannot affect editorial decisions.

10. Does BMJ Open impose any copyright restrictions?

Authors will retain copyright. Publishing using a creative commons licence will impose no (non-commercial) restrictions on articles' use.

11. How do I sign up for email alerts about published articles?

You can subscribe to receive BMJ Open email alerts within the article pages of the website and at http://bmjopen.bmj.com. Email alert options available for BMJ Open are:

• Electronic table of contents alerts
• Alerts when article is cited
• Alerts if corrections are posted

You can also sign up for RSS feeds that will update you when new content is published.

12. Is there a print edition?

No, BMJ Open is an online only resource

13. How do I subscribe to BMJ Open?

BMJ Open is a 'gold' open access journal - free to access for anyone with an internet connection.

14. How can my library subscribe?

As with individuals, no library or institutional subscriptions are required.

16. Where is BMJ Open indexed?

All articles published in BMJ Open will be deposited by us on authors' behalf in PubMed Central. BMJ Open will be submitted for evaluation to all relevant indexing services as soon as their requirements are met.

17. Does BMJ Open have an impact factor?

As the journal welcomes smaller scale and lower impact studies, BMJ Open will not deliberately pursue a high impact factor. However, to ensure authors' research as much exposure as possible the journal will be submitted to ISI for review for inclusion in the Web of Science when eligible.

BMJ Open will publish article-level metrics for all research that will provide a more accurate picture of an individual article's use.

18. What is the difference between BMJ Open and BMJ Case Reports?

BMJ Open does not publish case reports, only research articles. It does not republish research from other journals. BMJ Case Reports publishes cases in all disciplines so that healthcare professionals, researchers and others can easily find clinically important information on common and rare conditions. Case reports published in other BMJ Group journals will also be adapted for publication on BMJ Case Reports. BMJ Case Reports is not an open access journal.

19. Who do I contact if I would like more information about BMJ Open?
