Google Chrome and Mozilla Firefox are required. JavaScript and cookies need to be enabled in your browser.

Abstracts can only be submitted online via the online abstract submission form (will be available January 2023).

Abstracts & late breaking abstracts will be published as submitted in Clinical Nutrition ESPEN and each abstract will have a unique DOI. Abstracts will be published after the Congress and those abstracts not presented at the Congress will not be published. It is the responsibility of the submitting author to ensure that all details, including authorship, are correct. No changes will be allowed after final submission.

The rules for preparing the abstracts are on this page. Failure to observe these guidelines may result in disqualification.

Submission Process

  • Delegates, who would like to present their work at the Congress, either orally or as a poster, are invited to submit an abstract for consideration by the Abstract Scientific Committee.
  • A paper should not be submitted to the 45th ESPEN Congress if it has already been presented internationally.
  • Abstract submission is only possible via the online abstract submission form.
  • Please read carefully all the instructions available on the Internet and on the online abstract submission system before preparing your abstract.
  • The creation of a user account is required for the submission of an abstract. The account only needs to be created once and can be re-used for future abstract submission and registration to the conference. Submitters from last year’s meeting should use their existing account details.
  • Abstracts fulfilling all criteria can be saved in “Final submission” status. Only abstracts in “Final submission” status will be considered for the Congress.
  • Abstracts are accepted on a wide range of topics in clinical nutrition and metabolism. The submitter has to select the right topic for the abstract on the submission form. Available topics are:
    • T01 Nutritional assessment
    • T02 Nutritional epidemiology
    • T03 Macronutrients metabolism
    • T04 Neuroendocrine and immune systems
    • T05 Micronutrients

For standardisation, the acceptable length of the abstract is not more than 2’000 printable characters (title included).

This includes non-visible characters, such as spaces and line breaks. Authors’ details and conflict of interest are not included.

Please refer to the word count of the system as slight differences may occur when counting with WORD or similar programmes.

The abstract needs to be structured as follows:

  • Rationale: this section should contain 1-2 sentences that clearly indicate the scientific question of the study and its clinical (or other) importance.
  • Methods: this section should contain sufficient information to be able to understand the experimental design, the analytical techniques and the statistics used in the study.
  • Results: this section should contain objective data to answer the scientific question(s).
  • Conclusions: this section should provide only conclusions of the study directly supported by the results, along with implications for clinical practice, avoiding speculation and overgeneralisation.

One table can be included, but the total number of cells (columns + rows) may not exceed 16. Please note that tables may significantly reduce the number of the remaining allowed characters.

A paper cannot be accepted if the conflict-of-interest disclosure is not signed. On the online abstract form, provide the requested details for all authors.

Presentation of abstracts

  • Abstracts can be accepted either as a poster or oral communication.
  • The Abstract Scientific Committee will select submitted abstracts and determine whether they are accepted for oral presentation or poster display.
  • Posters should be a single page in portrait Format – more details on how to submit your poster will be provided in due time.

General remarks

  • Abbreviations should be defined.
  • Trade names cannot be mentioned in the title. However, trade names in brackets will be accepted in the body of the text.

  • No changes can be made to the abstract after the submission deadline of 12 April 2023, 23h59 CEST.
  • The reviewers will judge the abstracts according to the relevance to ESPEN, the standard of English, the objectivity of statements, description of what was done, suitability of methods to aims, conclusions confirmed by objective results, ethics, scientific value, potential clinical value, originality of work and overall impression.
  • Submitting authors will be notified by End-May 2023 whether their abstract has been accepted, and they will be informed at the same time about the date, time and form of their presentation. All notifications will be sent out to the e-mail address given on the submission form.
