Correspondence

Criteria

The BMC Series journals recognize the importance of post-publication commentary on published research as necessary to advancing scientific or academic discourse. Formal post-publication commentary on published papers can involve challenges, clarifications or, in some cases, replication of the published work and may, after peer review, be published online as Correspondence articles, usually alongside a Reply from the original authors.

Correspondence articles are interesting and timely scientific or academic comments and clarifications on original research papers published in the journal. These comments should be based on knowledge contemporaneous with the original paper, rather than subsequent scientific or academic developments.

If the submission serves only to identify an important error or mistake in the published paper, it will usually lead to the publication of a clarification statement (correction or retraction, for example). Please contact the journal for these cases. 

In all cases, the journal strongly encourages correspondents to first contact the authors of the paper directly as this can often resolve matters if it is a simple misunderstanding.

Correspondence articles and Replies are bidirectionally linked with the original published paper. This journal does not consider Correspondence articles on papers published in other journals. Contributions that do not comply with our submission criteria (see sections below) will not be considered.

Manuscript preparation and formatting

  • The article title of the initial Correspondence article should refer to, but not be identical to, the article title of the original published paper.
  • The main text should be as concise as possible, and ideally not exceed 1,200 words.
  • Contributions should start with a brief paragraph that summarizes the message of the article without specialized terminology, for a non-specialist readership. This paragraph should be used as the abstract for submission purposes.
  • Manuscripts should have a simple message that ideally requires only one or two small figures or tables.
  • The article should be measured in tone, and should not contain inflammatory or otherwise intemperate language.
  • As a guideline, contributions may have up to 15 references; reference style is as for research articles.
  • Supplementary Information is permitted at the editor's discretion.
  • Contributions should be submitted by email to the Editor for initial assessment. Please use the contact email address for the journal. 

Editorial Process

The editors will decide how to proceed on the basis of the potential interest to readers, importance and timeliness of the contribution. Authors should submit a pre-submission enquiry by email to the Editor for initial consideration. Details of the journal email address can be found under the Contact Us link. 

Correspondence submissions that meet the journal’s criteria are sent to the authors of the original paper for a formal response. The comments and formal response may then be sent to independent referees.

A Reply is published only when it adds to the debate, and not when it reiterates points already published. It should be confined to replying to the specific issue raised about the published paper.

Authors of the original publication must keep the information provided in Correspondence articles confidential and must not use it for their own research or for any other purpose apart from replying to the comment.

We will not consider appeals against decisions not to publish Correspondence articles unless the grounds for appeal consist of a previously overlooked and important scientific point and are clearly explained in these terms. 


Preparing your manuscript

Title page

The title page should:

·       present a title that includes, if appropriate, the study design e.g.:

o   "A versus B in the treatment of C: a randomized controlled trial", "X is a risk factor for Y: a case control study", "What is the impact of factor X on subject Y: A systematic review"

o   or for non-clinical or non-research studies: a description of what the article reports

·       list the full names, institutional addresses and email addresses for all authors

o   if a collaboration group should be listed as an author, please list the group name as an author. If you would like the names of the individual members of the group to be searchable through their individual PubMed records, please include this information in the “Acknowledgements” section in accordance with the instructions below

·       indicate the corresponding author

Abstract

No abstract. 

See the criteria section for this article type (located at the top of this page) for information on using the first paragraph as the abstract for submission only.

Keywords

Three to ten keywords representing the main content of the article.

Main text

This should contain the body of the article, and may also be broken into subsections with short, informative headings.

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.

Declarations

All manuscripts must contain the following sections under the heading 'Declarations':

  • Ethics approval and consent to participate
  • Consent for publication
  • Availability of data and material
  • Competing interests
  • Funding
  • Authors' contributions
  • Acknowledgements
  • 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.

Ethics approval and consent to participate

Manuscripts reporting studies involving human participants, human data or human tissue must:

  • include a statement on ethics approval and consent (even where the need for approval was waived)
  • include the name of the ethics committee that approved the study and the committee’s reference number if appropriate

Studies involving animals must include a statement on ethics approval.

See our editorial policies for more information.

If your manuscript does not report on or involve the use of any animal or human data or tissue, please state “Not applicable” in this section.

Consent for publication

If your manuscript contains any individual person’s data in any form (including individual details, images or videos), consent for publication must be obtained from that person, or in the case of children, their parent or legal guardian. All presentations of case reports must have consent for publication.

You can use your institutional consent form or our consent form if you prefer. You should not send the form to us on submission, but we may request to see a copy at any stage (including after publication).

See our editorial policies for more information on consent for publication.

If your manuscript does not contain data from any individual person, please state “Not applicable” in this section.

Availability of data and materials

All manuscripts must include an ‘Availability of data and materials’ statement. Data availability statements should include information on where data supporting the results reported in the article can be found including, where applicable, hyperlinks to publicly archived datasets analysed or generated during the study. By data we mean the minimal dataset that would be necessary to interpret, replicate and build upon the findings reported in the article. We recognise it is not always possible to share research data publicly, for instance when individual privacy could be compromised, and in such instances data availability should still be stated in the manuscript along with any conditions for access.

Data availability statements can take one of the following forms (or a combination of more than one if required for multiple datasets):

  • The datasets generated and/or analysed during the current study are available in the [NAME] repository, [PERSISTENT WEB LINK TO DATASETS]
  • The datasets used and/or analysed during the current study available from the corresponding author on reasonable request.
  • All data generated or analysed during this study are included in this published article [and its supplementary information files].
  • The datasets generated and/or analysed during the current study are not publicly available due [REASON WHY DATA ARE NOT PUBLIC] but are available from the corresponding author on reasonable request.
  • Data sharing is not applicable to this article as no datasets were generated or analysed during the current study.
  • The data that support the findings of this study are available from [third party name] but restrictions apply to the availability of these data, which were used under license for the current study, and so are not publicly available. Data are however available from the authors upon reasonable request and with permission of [third party name].
  • Not applicable. If your manuscript does not contain any data, please state 'Not applicable' in this section.

More examples of template data availability statements, which include examples of openly available and restricted access datasets, are available here.

BioMed Central also requires that authors cite any publicly available data on which the conclusions of the paper rely in the manuscript. Data citations should include a persistent identifier (such as a DOI) and should ideally be included in the reference list. Citations of datasets, when they appear in the reference list, should include the minimum information recommended by DataCite and follow journal style. Dataset identifiers including DOIs should be expressed as full URLs. For example:


Hao Z, AghaKouchak A, Nakhjiri N, Farahmand A. Global integrated drought monitoring and prediction system (GIDMaPS) data sets. figshare. 2014. http://dx.doi.org/10.6084/m9.figshare.853801

With the corresponding text in the Availability of data and materials statement:

The datasets generated during and/or analysed during the current study are available in the [NAME] repository, [PERSISTENT WEB LINK TO DATASETS].[Reference number]

Competing interests

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.

Please use the authors initials to refer to each author's competing interests in this section.

If you do not have any competing interests, please state "The authors declare that they have no competing interests" in this section.

Funding

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.

Authors' contributions

The individual contributions of authors to the manuscript should be specified in this section. Guidance and criteria for authorship can be found in our editorial policies.

Please use initials to refer to each author's contribution in this section, for example: "FC analyzed and interpreted the patient data regarding the hematological disease and the transplant. RH performed the histological examination of the kidney, and was a major contributor in writing the manuscript. All authors read and approved the final manuscript."

Acknowledgements

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.

If you do not have anyone to acknowledge, please write "Not applicable" in this section.

Group authorship (for manuscripts involving a collaboration group): if you would like the names of the individual members of a collaboration Group to be searchable through their individual PubMed records, 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.

Please note that individual names may not be present in the PubMed record at the time a published article is initially included in PubMed as it takes PubMed additional time to code this information.

Authors' information

This section is optional.

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).
