Putting research into context
- From August 1, 2010, authors are invited to submit their research papers with a section in the Discussion that puts the results into context with previous work (see Lancet 2010; 376: 10-11). Authors should provide a Panel explaining in brief how they arrived at their bottom line message
- The Discussion section should contain a full description and discussion of the context. Authors are also invited to either report their own, up-to-date systematic review or cite a recent systematic review of other trials, putting their trial into context of the review.
Panel: Research in context
This section should include a description of how authors searched for all the evidence. Authors should also say how they assessed the quality of that evidence — ie, how they selected and how they combined the evidence.
Authors should state here what their study adds to the totality of evidence when their study is added to previous work.
- We will consider clear and interesting Clinical Pictures submitted with a descriptive paragraph of 150 words
- Authors must obtain signed informed consent from the patient (see Patient and other consents)
- Currently, clinical pictures will be accepted as exclusive online only material, of which a random selection will go into the print journal as fillers when required. Pictures that are online only as well as those that are later published in print will be given a DOI and be submitted to the National Library of Medicine for PubMed listing
Blue section (Comment, World Report, Perspectives, Correspondence, etc)
- Editorials are the voice of The Lancet, and are written in-house by the journal's editorial-writing team and signed "The Lancet"
- Most Comments are commissioned, but spontaneous Comments are welcome on a paper or other report or event within the past month or so, or in the near future
- Comments should be about 700 words and ten references
- The place to respond to something we have published is in our Correspondence section
- See Conflict of Interest guidelines for Comments
- The Lancet has a function as an international newspaper covering news about science, medicine, policy issues, and people
- Most of the writers of World Report articles are professional journalists, but an important event in your country that might be of wider interest can be brought to the attention of our World Report editors via email@example.com
- Reviews of books and other media, Lifelines, and art of medicine pieces are often commissioned, but suggestions for contributions are welcome firstname.lastname@example.org
- Obituaries are written by our team of professional journalists, but we invite suggestions from readers for people whom we should feature — remarkable individuals who are internationally renowned for their contributions to medicine
- Please submit such suggestions within 3 weeks of an individual's death via email@example.com
- We welcome correspondence on content published in The Lancet or on other topics of interest to our readers
- Letters for publication in the print journal must reach us within 2 weeks of publication of the original item and should be no longer than 250 words
- Letters of general interest, unlinked to items published in the journal, can be up to 400 words long
- Correspondence letters are not usually peer reviewed (we rarely publish original research or Case Reports in this section), but the journal might invite replies from the authors of the original publication, or pass on letters to these authors
- Only one table or figure is permitted, and there should be no more than five references and five authors
- All accepted letters are edited, and proofs will be sent out to authors before publication
- Some letters might be chosen for online-only publication
Adverse drug reactions
- Reports of adverse drug reactions are peer reviewed and those we accept are published in the Correspondence section
- Length must not exceed 800 words, with only one table or figure, and no more than five references. No more than five authors are permitted
Department of Error
- Any substantial error in any article published in The Lancet should be corrected as soon as possible. Blame is not apportioned; the important thing is to set the record straight
- The Lancet journals have a policy for types of errors that we do and do not correct. We will always correct any error affecting a non-proprietary drug name, dose, or unit, any numerical error in the results, or any factual error in interpretation of results
Green section (Seminars, Reviews, Series, Viewpoints, etc)
Commissioned Seminars, Reviews, and Series
- Seminars are disease-oriented clinically focused overviews for the generalist, covering epidemiology, pathophysiology, diagnosis, management, and prevention; whereas Reviews have a narrower remit for a more specialised audience. We aim to provide comprehensive balanced Review papers for clinicians and researchers on topics that we judge to be of widespread interest
Complete transparency about the choice of material included is important to any Review paper. Therefore, all Seminars and Reviews, and some Series, should include a brief section entitled "Search strategy and selection criteria" stating the sources (including databases, MeSH and free text search terms and filters, and reference lists from journals or books) of the material covered, and the criteria used to include or exclude studies. Citations to papers published in non-peer-reviewed supplements are discouraged. Since these papers should be comprehensive, we encourage citation of publications in non-English languages. An example is shown below:
Search strategy and selection criteria
Data for this Review were identified by searches of MEDLINE, Current Contents, PubMed, and references from relevant articles using the search terms "sentinel node", "breast cancer", and "axilla". Abstracts and reports from meetings were included only when they related directly to previously published work. Only articles published in English between 1980 and 2006 were included.
- Seminars should be no more than 5000 words with a maximum of 140 references, and Reviews should be no more than 4500 words, with a maximum of 100 references. A 150-word unstructured summary should be included. These papers should include about five illustrations to aid the reader
- A hypothesis paper describes a substantial jump in thinking that is testable but not so easily testable that readers will wonder why you have not already done it. New data are not part of a hypothesis, but you must include a section on how to test your idea
- Sharing a new idea takes courage and concision. If you cannot express your line of thought in 1500 words, 20 references, and a 150-word unstructured summary, it is not a hypothesis
- Much of The Lancet's role in encouraging debate and opinion takes place in sections such as Public Health, Viewpoint, Essay, Reportage, and the Departments of Medical History, Ethics, Medicine and Art, and Literature and Medicine. 1500 words and 20 references are our general guidelines for papers in these sections
- Case reports are intended to inform, entertain, and inspire. Present a diagnostic conundrum, and explain how you solved it. Tell us about the presentation, history, examination, investigations, management, and outcome. In your discussion, educate the reader
- Case reports should tell readers about a condition or presentation that they might encounter — so novelty, rarity, and overspecialisation are not what we are looking for. Aim at the generalist: the family doctor, junior psychiatrist, surgeon in training, or the well informed medical student
- Use no more than 600 words and 5 references. Explanatory and graphic pictures (up to a maximum of two) can be helpful
- Consent for publication in print and electronically must be obtained from the patient or, if this is not possible, the next of kin before submission. SeePatient and other consents.
Manuscripts should be submitted in English. Authors writing in Chinese, Portuguese, or Spanish may wish to use the Webshop (http://webshop.elsevier.com/languageservices) to provide an English translation of their manuscript for submission.
A brief title, author name(s), preferred degree (one only), affiliation(s), and full address(es) of the authors must be included. The name and address of the corresponding author should be separately and clearly indicated along with email and telephone details.
Formatting of text
- Type a single space at the end of each sentence
- Do not use bold face for emphasis within text
- We use a comma before the final "and" or "or" in a list of items
- Type decimal points midline (ie, 23·4, not 23.4). To create a midline decimal on a PC: hold down ALT key and type 0183 on the number pad, or on a Mac: ALT shift 9
- Numbers one to ten are written out in words unless they are used as a unit of measurement, except in figures and tables
- Use single hard-returns to separate paragraphs. Do not use tabs or indents to start a paragraph
- Do not use the automated features of your software, such as hyphenation, endnotes, headers, or footers (especially for references). You can use page numbering
- Cite references in the text sequentially in the Vancouver numbering style, as a superscripted number after any punctuation mark. For example: ...as reported by Saito and colleagues.15
- Two references are cited separated by a comma, with no space. Three or more consecutive references are given as a range with an en rule. To create an en rule on a PC: hold down CTRL key and minus sign on the number pad, or on a Mac: ALT hyphen
- References in tables, figures, and panels should be in numerical order according to where the item is cited in the text
- Here is an example for a journal reference (note the use of tab, bold, italic, and the en rule or 'long' hyphen): ...15[tab]Saito N, Ebara S, Ohotsuka K, Kumeta J, Takaoka K. Natural history of scoliosis in spastic cerebral palsy. Lancet 1998; 351: 1687-[en rule]92.
- Give any subpart to the title of the article. Journal names are abbreviated in their standard form as in Index Medicus
- If there are six authors or fewer, give all six in the form: surname space initials comma
- If there are seven or more give the first three in the same way, followed by et al
- For a book, give any editors and the publisher, the city of publication, and year of publication
- For a chapter or section of a book, also give the authors and title of the section, and the page numbers
- For online material, please cite the URL, together with the date you accessed the website
- Online journal articles can be cited using the DOI number
- Do not put references in the Summary.

—Hourigan P. Ankle injuries. In: Chan D, ed. Sports medicine. London: Elsevier, 2008: 230-47.
- Numbered in order of mention in Webappendix and numbered separately from references in the full paper
- All images must have a minimum resolution of 300 dpi, width 107 mm
- Main figure heading should be in 10 point Times New Roman font BOLD
- Legends should be in 10 point, single spaced
- The paper to which the audio or video clip relates should be mentioned in the recording
- Audio clip and video files should be accompanied with brief text explaining the content of the audio, names of interviewers/interviewees, date of recording, and place of recording if relevant
- Written consent from all parties must be supplied at submission
- Audio material submitted as an mp3 file, no larger than 50 Mb
- Your paper may be selected for a podcast. If so, the Web Editor will contact you to arrange a pre-recorded interview to discuss your paper. For more information, see Audio.
- Video material should preferably be submitted in .mpg (or .mov, .avi, or .gif) format with aspect ratio of 16:9, no larger than 50 Mb
- We welcome your videos and invite you to submit any video material (reports, interviews, scans, imaging) for consideration in the online journal. Patient consent issues apply if there is a chance that the patient can be identified from either the article or accompanying video (see the above section on Patient and other consents).
- All video files can be submitted alongside your article in EES.
Disclosure of results before publication
- Presentation of data at a scientific meeting, as a poster, abstract, orally, on a CD, or as an abstract on the web does not conflict with submission toThe Lancet
- As a member journal of the International Committee for Medical Journal Editors, The Lancet does not regard results that are posted in the same clinical trials registry in which primary registration resides as prior publication, if the results are presented in the form of a brief structured abstract or table (<500 words; see Lancet 2007; 369: 1909-11). However, presentation of results in other circumstances (eg, investors’ meetings) is discouraged and could jeopardise consideration of the manuscript.
- For research papers that are judged to warrant fast dissemination, which will usually be randomised controlled trials, The Lancet will publish a peer-reviewed manuscript within 4 weeks of receipt
- Systematic reviews of randomised trials about diseases that have a major effect on human health also might warrant rapid peer review and publication
- If you wish to discuss your proposed submission with an editor, please call one of the editorial offices in London (+44  20 7424 4943), New York (+1 212 633 3667), or Beijing (+86 10 852 08872)
- See Articles section for manuscript requirements
Online First publication
- The Lancet increasingly publishes articles online ahead of print publication. You will be informed at least a week in advance of the Online First publication date
- The online article is identical to the version subsequently published in the print journal, and is citable by the digital object identifier (DOI) assigned at the time of online publication.
- The Lancet will assess protocols of randomised trials and systematic reviews and will publish on our website summaries of those protocols that survive review
- It is best to submit your protocol before the start of the trial; all trials should be registered
- We also make a commitment to seek peer review of any paper that reports the primary clinical data of a protocol that we have published (see Lancet 2008; 372: 189-190 and Lancet 2001; 357: 1819-20), and therefore encourage submission of such papers to The Lancet.
