Data note articles highlight and help to contextualise exceptional datasets to encourage reuse.
Data notes focus on a particular dataset or sets, and provide detailed methodology on data production, validation, and potential reuse. Manuscripts containing more detailed analyses of data should be submitted as a Research article.
One of the aims of a Data note is to incentivise faster release of data before subsequent detailed analysis has been carried out, although we do consider submission coordinated with or after publication of an analysis paper if the Data note adds value – by providing significant additional detail that might not have been appropriate in the research paper on data collection, data validation and re-use. It could also be associated with the release of intermediate or processed data, code and other supporting information that was not released in a companion paper.
The dataset(s) described in the manuscript must be available for our reviewers and editors to assess along with the manuscript. This can be done as an additional file in your submission or in an accessible repository of your choice (we recommend Dataverse repository).
Should the manuscript be approved for publication, the accompanying datasets must be accessible by any researcher wishing to use them under a Creative Commons CC0 waiver, without restrictions, such as the need for a material transfer agreement. Authors must clearly acknowledge any work upon which they are building, both published and unpublished, and cite such work when possible in the reference list with a DOI.
The information below details the section headings that you should include in your manuscript and what information should be within each section.
Please note that your manuscript must include a 'Declarations' section including all of the subheadings (please see below for more information).
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.
Preparing main manuscript text
This should list: the title of the article, which should include an accurate, clear and concise description of the reported work, avoiding abbreviations; and the full names, institutional addresses, e-mail addresses for all authors. The corresponding author should also be indicated. It is suitable, should the authors of the work prefer, to designate authorship as a Consortium or Project. In such cases, a contact author must still be provided, and a complete author list/institutions/emails, etc. should be included in the author contribution section. See the following as an example.
250 words maximum
The abstract of the manuscript must be structured into separate sections:
Background: a presentation of the interest or relevance of these data for the broader community;
Findings: a very brief preview of the data type(s) produced, the methods used, and information relevant to data validation;
Conclusions: a short summary of the potential uses of these data and implications for the field. Please minimize the use of abbreviations and do not cite references in the abstract.
Three to ten keywords representing the main content of the article.
A brief statement providing background and purpose for the collection of these data should be presented for readers without specialist knowledge in that area. A clear description of the data, the protocol(s) for data collection, data curation and quality control, as well as potential uses should be included. Please try to keep this concise and close to 1,000 words and 10 references if possible; however, word restrictions may not apply in cases where datasets or data collection/validation protocols are complex or require substantial details to properly describe the work.
Experiments supporting and demonstrating the technical quality of the dataset should be presented. Data note articles can be published alongside traditional Research articles, and any previously published or in-press research using the data should be highlighted, as it will aid validation and demonstrate use. Brief instructions and suggestions of downstream applications that may help other researchers with reuse of the data are also encouraged. Manuscripts that contain extensive biological analyses along with data production should be submitted as a Research article.
Availability of supporting data
Reproductive Health requires authors to deposit the data set(s) supporting the results reported in submitted manuscripts in a publicly-accessible data repository, such as Dataverse. This section must include the name of the repository and the permanent identifier or accession number and persistent hyperlinks for the data sets (if appropriate). The following format is required:
"The data set(s) supporting the results of this article is (are) available in the [repository name] repository, [cite unique persistent identifier]."
Following the Joint Declaration of Data Citation Principles, where appropriate we ask that the data sets be cited where it is first mentioned in the manuscript, and included in the reference list. If a DOI has been issued to a dataset please always cite it using the DOI rather than the less stable URL the DOI resolves to (e.g. http://dx.doi.org/10.5524/100044 rather than http://gigadb.org/dataset/100044).

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
- 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.
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 any 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 generated and/or analysed during the current study are 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
