From January 2015, only guidelines, standardization, consensus, review and educational articles will be published in full in the print version of the Journal. For all other articles the print version of the Journal will include only structured summaries, with the full length version of the article appearing online. Therefore, a structured summary is required for all full length articles submitted to the Journal from now on, and this should be uploaded with the manuscript files. Guidelines for the structured summary are detailed below and they can also be found in the Guide for Authors, within the section ‘Essential title page information’.
A factual summary of the article is required between 400 and 600 words, along with a figure and/or table. The figure/table should be unique to the summary, and not a duplicate of one used within the article body.
The summary should be sub-divided into a number of headings. Authors may choose the headings they think are most appropriate for their article, but we suggest the following general approach:
A short introduction/background paragraph (may include a figure).
An objective (a short statement of the study aims).
Study design (subjects/patients/materials/methods).
Results (no long lists of detailed values, but stating the main findings). A figure/table would be very helpful for this section.
Discussion. This should be concise and list the limitations of the study and compare the major outcome to the literature.
Conclusion, essentially assessing whether the aims have been met.
References should be avoided. Non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the summary itself. An example of an appropriate structured summary is printed on the following page. This is a guide and not prescriptive.
Immediately after the summary, provide a list of 3–6 keywords, using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, ‘and’, ‘of’). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.
