Arrangement of the manuscript

All pages (including references, tables and their captions, figure captions and [where possible] figures) should be saved in a single electronic file.

The manuscript should include the following: (i) title page, (ii) abstract, (iii) main text (introduction, materials and methods, results, discussion), (iv) references, (v) figure legends, (vi) tables, (vii) figures.

Title page.  The first page should contain: title of paper, suggested running headline of not more than 30 characters (including both letters and spaces) and author's name, department, institution, city and country.

Abstract.  For all ‘Original Articles’ but not for ‘Case Reports’ and ‘Reviews’ (which should have a short, conventional abstract of approximately 100 words) a structured abstract of approximately 250 words should be given. The subtitles shown below should be used, whenever applicable:

Objectives. Give a clear statement of the main aim of the study and the main hypothesis tested, if any.

Design. Describe the design of the study and mention, as appropriate, randomization, blinding, placebo-control, case-control, cross-over, criterion standards for diagnostic tests, and so on.

Setting. Describe the setting of the study, including the level of clinical care (primary care, etc.) and the number of participating centres.

Subjects. State the entry requirements, selection procedures and the number of subjects approached, entering and completing the study.

Interventions. Describe the main features of any interventions, including the method and duration of their use.

Main outcome measures. State the primary outcome measures as planned before the data were collected. If the paper does not emphasize the planned main outcome measures, this should be stated and explained.

Results. Give the main results of the study.

Conclusions. State the primary conclusions of the study and their clinical implications. Suggest areas for further research, if appropriate.

Keywords: List not more than six keywords below the abstract. Only use terms from the ‘Medical Subject Headings’ list from Index Medicus.

Ethical considerations.  For studies involving ethical problems approval by the local ethical authority should be indicated in the ‘Materials and methods’ section.


Conflict of Interest Statement.  A statement of financial or other relationship that might lead to a conflict of interest should be declared. It should also be stated if you have nothing to declare.

Correspondence address.  The last page of the reference list should carry the name and address of the author to whom correspondence, including requests for offprints, should be sent. Telephone and fax numbers (as well as an e-mail address if available) should also be given. (The responsible author is advised to have an alternative proof reader amongst the coauthors; give the name and address of this ‘second’ author here.)

Tables and figures.  Figure captions should follow the correspondence address and must be comprehensive so that they are understandable without reference to the text. All figures should be cited in the text. Authors are encouraged to submit figures in colour where appropriate. Further information on preparing high-resolution digital files can be found at

Note that in case of use of a previously published table, figure or illustration, written permission from the publisher should be submitted with the manuscript.

In the full-text online edition of the journal, figure legends may be truncated in abbreviated links to the full screen version. Therefore the first 100 characters of any legend should inform the reader of key aspects of the figure.

Tables should follow the figure legends. Only horizontal lines should be used.


Proofs will be sent via e-mail as an Acrobat PDF (portable document format) file. The e-mail server must be able to accept attachments up to 4 MB in size. Acrobat Reader will be required in order to read this file. This software can be downloaded (free of charge) from the following Web site:

This will enable the file to be opened, read on screen, and printed out in order for any corrections to be added. Further instructions will be sent with the proof. Proofs will be posted if no e-mail address is available; in your absence, please arrange for a colleague to access your e-mail to retrieve the proofs.

Review and action

Manuscripts are examined by the editorial group and are usually sent to outside reviewers. To facilitate and speed up the review process we encourage the authors to suggest two or three names of possible reviewers.

Rapid communication

Concise papers (not exceeding 1500 words) representing new but completed work which is of unusually high priority and significance, as clearly indicated by the authors in the covering letter, will be considered as Rapid communications. Papers will be reviewed immediately and publication should occur within 8 weeks of acceptance of the manuscript, with a few exceptions.
