General Information About Your Abstract

Your abstract should be submitted in English and must include:

• A list of authors with their professional affiliations: Make sure the names, degrees, and affiliations are consistent across all abstracts you submit.
• A designated speaker
• A title
• The main text of the abstract
• A topic and a list of keywords

2

Authors

• Please create the list of authors using the “Create a New Author” form.
• Once created, you may add authors and select a designated speaker. After final submission, no new authors can be added to the abstract.
• Each speaker must follow the Presentation Guidelines, and must be registered for the congress by September 20^th at the latest (cf. Presentation Guidelines).

 Select an Abstract Type and a Topic

• Choose the type of abstract to submit: “Original Research” for original, unpublished research.
• Please note that case reports and images, if accepted, will only be selected for Poster Presentation, not for Oral Presentation. “Original Research” abstracts that are accepted can be selected as either Poster Presentation or Oral Presentation.
• This will depend on the reviewers’ scores.
• Then, please select the appropriate topic from the drop down list below.

Title

• Your title must be as short as possible.
• The title should succinctly summarize the abstract, include topic-related keywords and incorporate the study design (e.g., survey, observational, trial, systematic review).
• The title should be written in lowercase, with an initial capital letter. Use capital and lower-case letters as appropriate for abbreviations in title (e.g. mRNA).

• Avoid using small capitals or all capitals in the title.
• Avoid using asterisks or notes in the title.

• Avoid using bullet lists in your abstract.
• Do not include bibliographic references in the abstract text.
• If abbreviations are used, spell out the full name when first mentioned, followed by the abbreviation in parentheses.
