Commentaries are short, narrowly focused articles of contemporary interest and usually take one of two forms:
- The first form is a discussion of an article or trial that was recently published or that is soon to be published, and that is interesting enough to warrant further comment or explanation. This type of commentary discusses specific issues within a subject area rather than the whole field, explains the implications of the article and puts it in context. Opinions are welcome as long as they are factually based.
- The second form is more editorial in nature and covers an aspect of an issue that is relevant to the journal's scope, for example discussion of the impact of new technology on research and treatment.
A maximum of ten articles may be included in the references.
Commentaries should not exceed 9000 words
Preparing your manuscript
The title page should:
- present a title that includes, if appropriate, the research design or for non-research studies: a description of what the article reports
- list the full names, institutional addresses and email addresses for all authors
- if a collaboration group should be listed as an author, please list the Group name as an author and include the names of the individual members of the Group in the “Acknowledgements” section in accordance with the instructions below
- indicate the corresponding author
The abstract should briefly summarize the aim, findings or purpose of the article. Please minimize the use of abbreviations and do not cite references in the abstract.
See the criteria section for this article type (located at the top of this page) for information on article word limits.
Three to ten keywords representing the main content of the article.
The Introduction section should explain the background to the article, its aims, a summary of a search of the existing literature and the issue under discussion.
This should contain the body of the article, and may also be broken into subsections with short, informative headings.
This should state clearly the main conclusions and include an explanation of their relevance or importance to the field.
All manuscripts must contain the following sections under the heading 'Declarations':
- Availability of data and material
- Competing interests
- Authors' contributions
- Authors' information (optional)
Please see below for details on the information to be included in these sections.
If any of the sections are not relevant to your manuscript, please include the heading and write 'Not applicable' for that section.
List of abbreviations
If abbreviations are used in the text they should be defined in the text at first use, and a list of abbreviations should be provided.
Availability of data and materials
For all journals, SpringerOpen strongly encourages all datasets on which the conclusions of the manuscript rely to be either deposited in publicly available repositories (where available and appropriate) or presented in the main paper or additional supporting files, in machine-readable format (such as spreadsheets rather than PDFs) whenever possible. Please see the list of recommended repositories in our editorial policies.
For some journals, deposition of the data on which the conclusions of the manuscript rely is an absolute requirement. Please check the Criteria section for this article type (located at the top of this page) for journal specific policies.
For all journals, authors must include an “Availability of data and materials” section in their article detailing where the data supporting their findings can be found. If you do not wish to share your data, please state that data will not be shared, and state the reason.
For instructions on how to cite your data and format this section see preparation/style and formatting.
All financial and non-financial competing interests must be declared in this section. See our editorial policies for a full explanation of competing interests. If you are unsure whether you or any of your co-authors have a competing interest please contact the editorial office.
All sources of funding for the research reported should be declared. The role of the funding body in the design of the study and collection, analysis, and interpretation of data and in writing the manuscript should be declared.
The individual contributions of authors to the manuscript should be specified in this section.
Please acknowledge anyone who contributed towards the article who does not meet the criteria for authorship including anyone who provided professional writing services or materials.
Authors should obtain permission to acknowledge from all those mentioned in the Acknowledgements section.
See our editorial policies for a full explanation of acknowledgements and authorship criteria.
Group authorship: if you would like the names of the individual members of a collaboration Group to be searchable through their individual PubMed records (where applicable), please ensure that the title of the collaboration Group is included on the title page and in the submission system and also include collaborating author names as the last paragraph of the “Acknowledgements” section. Please add authors in the format First Name, Middle initial(s) (optional), Last Name. You can add institution or country information for each author if you wish, but this should be consistent across all authors.
You may choose to use this section to include any relevant information about the author(s) that may aid the reader's interpretation of the article, and understand the standpoint of the author(s). This may include details about the authors' qualifications, current positions they hold at institutions or societies, or any other relevant background information. Please refer to authors using their initials. Note this section should not be used to describe any competing interests.
Endnotes should be designated within the text using a superscript lowercase letter and all notes (along with their corresponding letter) should be included in the Endnotes section. Please format this section in a paragraph rather than a list.
How to format your references
Examples of the American Psychological Society (APS) reference style are shown below. Please ensure that the reference style is followed precisely; if the references are not in the correct style, they may need to be retyped and carefully proofread.
Web links and URLs: All web links and URLs, including links to the authors' own websites, should be given a reference number and included in the reference list rather than within the text of the manuscript. They should be provided in full, including both the title of the site and the URL, as well as the date the site was accessed, in the following format: The Mouse Tumor Biology Database. http://tumor.informatics.jax.org/mtbwi/index.do. Accessed 20 May 2013. If an author or group of authors can clearly be associated with a web link, such as for weblogs, then they should be included in the reference.
Authors may wish to make use of reference management software to ensure that reference lists are correctly formatted. An example of such software is Papers, which is part of Springer Science+Business Media.
