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 over generalisation.

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 on-line abstract form, provide the requested details for all authors.
