Extended Research Article

Key principles

  • The purpose of the extended research article is to provide a single account of the whole research award, providing all the relevant data and evidence to support its conclusions against the overarching research questions and objectives.
  • The format is to be used only after prior agreement from the publications team, when the Threaded Publication Model is either not appropriate or proportionate for reporting of the NIHR award.
  • The main body of the extended research article should not be more than 50,000 words. Fewer words are acceptable and will depend on the nature of the project. This limit includes all text, text within tables, and text within figures and boxes which are contained within the main body of the manuscript. Please note that your manuscript will not proceed to peer review if it is over this limit. The limit does NOT include the Abstract, Scientific Summary and Plain Language Summary (which continue to have their own individual word limits). It also excludes the table of contents, references, appendices, supplementary material and additional information (CRediT statement, Data sharing statement, Ethics statement, Information Governance Statement).
  • Articles over the word count will be sent back to the award team to reduce.
  • Award teams should follow the appropriate reporting guidelines for their study type. A comprehensive list of available reporting guidelines, listed by study type, can be found on the EQUATOR Network website.
  • Within the main body of the extended research article, authors have the flexibility to include a narrative that captures a critical and reflective discussion.
  • There is some flexibility to the ordering and naming of some of the main body headings so that the extended research article meets the need of the intended audiences e.g. policy review, patient partnerships, practitioners.
  • However, please note the following headings are mandatory and must appear in the article to fulfilwiderNIHR commitments in these areas:
    • Patient and Public Involvement
    • Equality, Diversity and Inclusion
    • Impact and Learning
    • Research Recommendations.
  • Once the article has completed the editorial and production process it will be published as a single issue of the relevant journal.
