The reviewers will judge the abstracts according to the following criteria:

  • Is the abstract original?

  • Does it address an important scientific question?

  • Is the abstract clearly written with all salient facts?

  • Does the work adhere to ethical guidelines?

  • Is there evidence of statistical method if appropriate?

  • Are the conclusions justified by the results?

​Please note:

  • No revisions can be made after the abstract deadline. To ensure the integrity of the review process, revisions to abstracts will not be accepted after the abstract submission deadline. This is inclusive of any changes to the list of co-authors.

  • The highest quality abstracts will be selected for an oral presentation.

  • Oral Presentation: Presenting authors of abstracts selected for an oral presentation will be informed about the date and time of the session. The presenting author will be required to be in-person and be required to agree to have their recorded presentation available on the virtual platform for 30 days post congress. No virtual presentations will be offered and presentation guidelines will be made available online two (2) months prior to the congress.

  • Poster Presentation: Poster presenters will be informed about the date and time of the poster session. The presenting author will be required to be in-person. No virtual poster presentations will be offered. Poster guidelines are available here. Posters will be organized using the topics chosen by the submitter in the online system.

Participants who submit and abstract to the ISTH Congress are eligible to apply for a Fundamental Research Career Development Award. Up to three annual awards of up to $50,000 USD will be given in the following categories:

  • Fundamental Mechanisms of Thrombosis

  • Fundamental Mechanisms of Hemostasis

  • Non-canonical Interactions of the Hemostatic System

Technical Requirements
The online abstract submission system works best with Google Chrome and Mozilla Firefox. Cookies and JavaScript need to be enabled.


Language Setting of Your Keyboard
The keyboard configuration of computers in non-Western countries may cause problems with the printing of the abstracts when special non-Western characters are used. To avoid these problems the language setting of your computer should be changed.

To do this select "Start" then Settings", then "Control Panel" and then choosing "Keyboard." Once in this menu, set the language of your computer to English (United States) or US (International). Next, open MS Word (or the word processing software you are using) and set the font type to Arial.  

In the preparation of your abstract, if you require certain special characters that are not available, (e.g. '±', '®', 'μ'), use the insert symbol feature (special characters). To do this, select Arial as the font (unicoded, if possible), then select the required character, and copy and paste the symbol into the text of the abstract. If a special character is still not available, describe the character, e.g. 'alpha’.
