For standardisation, the acceptable length of the abstract is of 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.


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

Presentation of abstracts

  • Abstracts can be accepted either as a poster or oral communication.
  • Only abstracts of authors who have confirmed the presentation and are duly registered by the deadline 21 June 2024, will be scheduled and included in the Abstract publication in Clinical Nutrition.
  • The presenters will receive a dedicated email with detailed instructions to confirm their presentation and register. It is mandatory that the same user account is used for the registration and abstract submission if the presenter wishes to register before receiving notice on acceptance/rejection.
