Sexually Transmitted Infections selects original papers on the basis of their likely appeal to its readership. Papers we select for publication will:

  • Be of interest to practitioners, policy makers, trainees and researchers wishing to keep themselves up to date in the field of clinical, epidemiological, sociological and laboratory aspects of STIs and HIV.
  • Be clearly and correctly expressed. Many of our valued contributors do not speak English as their first language. If you feel unsure of your competence in English, please show your paper to a colleague who speaks English, preferably a native speaker, before making your submission.
  • Be intelligible to our broad international readership. Do not assume familiarity with cultural or institutional facts that are specific to the place in which the research is undertaken.
  • Please explain any details that are likely to cause confusion or misunderstanding for readers from other cultural backgrounds.

Papers are considered on the basis that they are submitted solely to this journal and do not duplicate material already published, or submitted in another manuscript. In cases of doubt, and whenever material from the same study/dataset has been submitted or published elsewhere, please mention this to the editor in your cover letter, and explain the relationship between the manuscripts and how they differ. Please also submit the published material in a supplementary file for editors and reviewers along with your manuscript. We recognise that there may be a need to report the same Methods for multiple studies. If this is the case, please consult http://publicationethics.org text recycling guidelines, and consider what repeated information can be given by referring to another manuscript, or in online only supplementary material.

Word count and supplementary material

The vast majority of articles fit comfortably within our word limits.  However it is sometimes appropriate to provide supplementary material which may be published online only.  Examples may include questionnaires, additional data tables, additional references or detailed aspects of laboratory methods which would be of interest only to a specialist. Any supplementary material must be uploaded as a Supplementary File for Review and should be clearly referenced in the body of the paper to e.g. Web reference 1, Appendix 2.  The publication of supplementary material is at the discretion of the Editor  and should not be considered a substitute for presenting a clear, complete manuscript within the word limit.

Quality improvement reports need to provide all the information a reader needs to assess the applicability of the quality intervention in another setting.  For these, we generally recommend the SQUIRE guidelines.

Observational studies should generally follow the STROBE guidance.  The results section should begin with the primary outcome measure, and give the results with 95% confidence intervals. Statistics should include, at the very least:

For a cohort study:

  • Absolute event rates over time (e.g. 10 years) among exposed and non-exposed groups;
  • Absolute risk difference;
  • Relative risk (RR) or hazard ratio (HR) for strength of association between exposure and outcome;
  • Where multivariable analyses have been conducted, report both the crude and adjusted analyses, with 95% confidence intervals.

For a case control study:

  • Odds ratio (OR) for strength of association between exposure and outcome.

For a study of a diagnostic test:

  • Sensitivity and specificity;
  • Positive and negative predictive values (PPV and NPV).

For clinical trials:

  • Absolute event rates among experimental and control groups;
  • Relative risk reduction (RRR);
  • Number needed to treat or harm (NNT or NNH) and its 95% confidence interval (or, if the trial is of a public health intervention, number helped per 1,000 or 100,000).

The discussion section must be well structured, and should include the following five
elements:

  • A brief statement of your principal findings;
  • An assessment of the strengths and weaknesses of your study;
  • A discussion of these strengths and weaknesses in relation to the strengths and weaknesses of comparable studies;
  • A summary of the meaning of your study, offering possible explanations of your findings and their relevance for clinicians and policymakers;
  • A consideration of unanswered questions and the possibilities for future research
  • The take home message for readers.

Research checklists

The EQUATOR Network is an excellent resource for reporting guidelines for a wide range of study types and contains many useful resources for authors. BMJ requires compliance to the following reporting guidelines. Please upload the relevant completed checklist for your study type with your submission, and label it “Research checklist”. If no relevant checklist is available for your study type, this can be indicated on the submission form.

CONSORT statement – Required for all randomised controlled trials
PRISMA statement – Required for all systematic reviews
EVEREST statement – Required for all economic evaluations
STARD statement – Required for all diagnostic research papers
STROBE statement – Required for all observational studies
STROBE-RDS statement – Required for Respondent-Driven Sampling Studies
SQUIRE statement – Required for all quality improvement studies

Word versions of the STROBE checklists are available below:
STROBE checklist for case-control studies
STROBE checklist for cohort studies
STROBE checklist for cross-sectional studies


Abstracts in other languages

For publications originating from countries where English is not the primary language, authors will be encouraged also to supply the abstract of their paper in their native language. This will be requested upon acceptance and published online only as a supplementary file alongside the English version. Authors should be aware that the translated abstract will not be copyedited or typeset and BMJ takes no responsibility for any errors in the non-English version.


Video abstracts

We welcome video abstracts to accompany accepted research articles. These allow authors to personally talk through their work beyond the restrictions of a formal article to improve the user’s understanding.

Note that we will not ask you to consider submitting a video abstract until your paper has been accepted. Please do not try to upload a video abstract upon initial submission of your manuscript.

Guidance on video abstracts is available on the BMJ Author Hub.

All video abstracts will be assessed for suitability by the editorial team and publication is not guaranteed. In some cases editors may request edits to the video.

Video abstracts are embedded within the research article online and also published separately on the journal’s YouTube channel. They are published under the same copyright terms as the associated article.


Article processing charges

During submission, authors can choose to have their article published open access for 1950 GBP (exclusive of VAT for UK and EU authors). Authors can also choose to publish their article in colour for the print edition – instead of the default option of black and white – for 250 GBP. There are no submission, page or online-only colour figure charges.

For more information on open access, funder compliance and institutional programmes please refer to the BMJ Author Hub open access page.

Data sharing

Sexually Transmitted Infections adheres to BMJ’s Tier 3 data policy. We strongly encourage that data generated by your research that supports your article be made available as soon as possible, wherever legally and ethically possible. All research articles must contain a Data Availability Statement. For more information and FAQs, please see BMJ’s full Data Sharing Policy page.

ORCID

Sexually Transmitted Infections mandates ORCID iDs for the submitting author at the time of article submission; co-authors and reviewers are strongly encouraged to also connect their ScholarOne accounts to ORCID. We strongly believe that the increased use and integration of ORCID iDs will be beneficial for the whole research community.

Please find more information about ORCID and BMJ’s policy on our Author Hub.

Submission guidelines

Please review the below article type specifications including the required article lengths, illustrations, table limits and reference counts. The word count excludes the title page, abstract, tables, acknowledgements, contributions and references. Manuscripts should be as succinct as possible.

For further support when making your submission please refer to the resources available on the BMJ Author Hub. Here you will find information on writing and formatting your research through to the peer review process and promoting your paper. You may also wish to use the language editing and translation services provided by BMJ Author Services.

If your article is accepted you can take advantage of BMJ’s partnership with Kudos, a free service to help you maximise your article’s reach.

Original article or short report

General guidance

Some types of research study that we frequently publish are:

  • Controlled trials (randomised or not randomised);
  • Observational studies;
  • Diagnostic accuracy studies;
  • Basic science;
  • Qualitative research;
  • Service improvement or quality improvement reports, which may include audits;
  • Economic evaluations;
  • Modelling studies

Your paper should be well organized and clearly structured. Your introduction (and your abstract) should contain a clear statement of the objectives of the study and the major hypothesis tested or research question posed.  Make sure that the messages of your abstract are in agreement with the messages in the body of the article.

Your methods section should contain, in all cases, information about:

  • design – including, where appropriate, such factors as prospective, randomisation, blinding, placebo control, case control, crossover, sample size calculation, a statement of the primary outcome and whether a protocol is available;
  • setting – including, where appropriate, the level of care (e.g. primary/secondary, and the number of participating centres). Be general rather than give the name of the specific centre, but give the geographical location if this is important ;
  • participants – including, where appropriate, numbers eligible and enrolled in the study, sex, and ethnic group. Give clear definitions of how participants were selected, of entry and exclusion criteria.

In the case of trials the methods section should also contain information regarding interventions – what, how, when, and for how long.

You should use research reporting guidelines to ensure that all necessary elements of your study are reported.  Guidelines improve the quality of reporting so that reviewers find less to criticize, and help the editors to ensure that all necessary information is concisely presented.  This will increase the chances of your published work being cited and its implications for practice being taken seriously. Whatever your study design, you should upload an appropriate research checklist as a Supplementary File for Review.  This helps editors and reviewers decide whether all necessary information has been presented.

Original article or short report?

Authors may choose to present their research in one of two forms:

  • a full length article (with a maximum of 3000 words, and a maximum of four tables/figures and 30 references except in the case of systematic reviews where 60 references are permitted);
  • a short report (with a maximum of 1500 words, and a maximum of one table/figure and 10 references).

You should consider presenting your findings as a full length original article rather than a short report in the following situations:

  • where the research is generalizable and of widespread significance;
  • where your work provides a stand-alone contribution to the literature;
  • where the findings relate to a substantial piece of research, and not only a pilot or preliminary investigation.

You should consider presenting your findings as a short report rather than an original article in the following situations:

  • where the research, though interesting, is of mainly local significance;
  • where your findings provide a largely additional or complementary perspective on existing research;
  • where these findings correspond to a still early and relatively incomplete stage in the development of your project.

Both original articles and short reports should be prefaced with an abstract of no more than 300 words (additional to the 3000/1500 words of the main body of the text). Structure your abstract under the headings: Objectives, Methods, Results, Conclusions. For an example of an abstract, please view the PDF files of an article and a short report given below.

Original articles must, in addition to an abstract, include as part of the text a key messages box. This should contain three or four bullet points of no more than 25 words each, highlighting the main features of, and lessons from, the paper. For an example of a key messages box, please view the PDF file of an article given below.

In the case of articles we are sometimes able to publish online only supplementary material, but the version for the print issue must be self-contained.

Review (Systematic review, meta-analysis or clinical review)

We welcome systematic reviews and meta-analyses.  A systematic review is a review of a clearly formulated question that uses systematic and explicit methods to identify, select, and critically appraise relevant research, and to collect and analyse data from the studies that are included in the review. Statistical methods (meta-analysis) may or may not be used to analyse and summarize the results of the included studies. Meta-analysis refers to the use of statistical techniques in a systematic review to integrate the results of included studies.

Systematic reviews with or without meta-analysis have a word limit of 3,000 words and should follow the PRISMA guidelines. They should contain no more than four tables/figures and a maximum of 60 references. Preface your review with an abstract of no more than 300 words (additional to the 3,000 words of the main body of the text), structured in accordance with PRISMA guidelines. Include a key messages box. For an example of an abstract and a key message box, view the PDF file given below.

Clinical reviews are generally commissioned, often in relation to special issues or supplements. We very rarely publish unsolicited clinical reviews.  The Editors are willing to discuss proposed clinical reviews, but please first consider the possibility of an Educational article.   They are subject to peer review in the usual way.  It is unusual for the journal to publish an unsolicited clinical review.  Where such a review has been commissioned, it should meet the standard formatting requirements for research articles, normally with a maximum of 30 references.

Education

We welcome proposals for educational articles. They are intended to provide advice and a basis for discussion on clinical or organizational aspects of STI diagnosis and care, especially where these are not fully addressed by guidelines. They often address “grey areas” of practice and are sometimes illustrated by case studies. These are subject to peer review to ensure that they present a balanced view and are relevant to our clinical readers. Though most address UK clinical practice, we welcome educational articles that address a global audience.

Educational articles should be a maximum of 1500 words, or fewer if tables/figures are included.

View an example of an educational article (PDF).

Case report

We occasionally publish individual case reports, if – only if – they convey an important learning point for our community of clinicians (e.g. cases involving a new manifestation of a disease, or important diagnostic or management issues). It is vital, if you are seeking publication in STI, that you make absolutely clear in your covering letter, as well as in the case report itself, why you see the lessons of the case to be important for other people’s practice.

In cases of submitted case reports that the editorial committee to be of insufficient importance for publication, we would often advise submission to BMJ Case Reports.

Case reports should not exceed 750 words, and should contain a maximum of 1 table and 10 references. They should be prefaced by an abstract of not more than 150 words.

Please note that patient permission is required for the use of images (see electronic submission system for consent form).

Your case report needs to be well structured and should contain the following elements:

  • Background – why you think the case is important;
  • Presentation – presenting important features; medical/social/family history;
  • Investigations – if relevant;
  • Differential diagnosis – if relevant;
  • Treatment – if relevant;
  • Discussion – including a very brief review of similar published cases;
  • Learning points (in the Key Messages box).

View an example of a case report (PDF).

Research letter

Research letters are used to report data that are not yet ready for publication as a short report or full length manuscript.  They are sometimes peer reviewed, but should not be automatically regarded as a peer-reviewed publication.

Like any other manuscript, research letters should reference any other publications from the same study population and describe the relationship between the two publications. We do not re-publish material that has already appeared in a conference abstract book. A letter can only be published if it adds significantly to what is already published on the same study population. The original publication should always be cited.

Research letters are restricted to a maximum of 500 words plus one small table or figure. Letters do not require an abstract and should have no more than five references.

For research letters presenting outbreak reports or audit reports, additional information may be published online only as supplementary material. This may include data or information that may be of interest to practitioners in some settings but which is too detailed and/or local in its interest to meet the expectations of the majority of the journal’s audience.



Correspondence

Letters in response to articles published in the journal are welcomed and should be submitted electronically via the journal’s website. Contributors should go to the abstract or full text of the article in question and click on the ‘Responses’ tab.

Letters relating to or responding to previously published items in the journal will be reviewed by the editor and shown to those authors of the original article, where appropriate. The authors will be invited to submit a response. Selected letters may be published in print alongside the authors’ responses.

Responses are limited to a maximum of 300 words with no tables or figures OR a maximum of 150 words with a single small table or figure. References are limited to 3, with one of those being the STI paper to which the response refers.



BASHH column

The purpose of this column is to make readers aware of the work & activities of BASHH and to discuss developments of health policy, education etc. within the UK and how they will/might affect the specialty of GU medicine. These are commissioned papers and are limited to 750 words including references (or fewer, if any figures/tables are included).



Clinical guideline

Clinical guidelines may published in STI when they are of interest to a wide audience and present a significant change or innovation. They should not exceed the normal word count for an original research article. They should refer the reader to the definitive version of the Guideline (often longer) published by a professional body. This will minimise potential for confusion or inconsistency.

The purpose of publishing guidelines in the journal is both to provide information on the rationale and need for change, and to document new recommendations for practice, so the introduction should have educational content updating the field. When adapting guidelines for the journal, bear in mind the audience of practitioners, researchers and policymakers.


Supplements

The BMJ Publishing Group journals are willing to consider publishing supplements to regular issues. Supplement proposals may be made at the request of:

  • The journal editor, an editorial board member or a learned society may wish to organise a meeting, sponsorship may be sought and the proceedings published as a supplement.
  • The journal editor, editorial board member or learned society may wish to commission a supplement on a particular theme or topic. Again, sponsorship may be sought.
  • The BMJPG itself may have proposals for supplements where sponsorship may be necessary.
  • A sponsoring organisation, often a pharmaceutical company or a charitable foundation, that wishes to arrange a meeting, the proceedings of which will be published as a supplement.

In all cases, it is vital that the journal’s integrity, independence and academic reputation is not compromised in any way.

For further information on criteria that must be fulfilled, download the supplements guidelines.

When contacting us regarding a potential supplement, please include as much of the information below as possible.

  • Journal in which you would like the supplement published
  • Title of supplement and/or meeting on which it is based
  • Date of meeting on which it is based
  • Proposed table of contents with provisional article titles and proposed authors
  • An indication of whether authors have agreed to participate
  • Sponsor information including any relevant deadlines
  • An indication of the expected length of each paper Guest Editor proposals if appropriate
