EAHAD’s objectives are to foster scientific advancement in the field of inherited and acquired bleeding disorders in Europe, to encourage research and to provide a wide forum for discussion. Delegates who would like to present their work at the meeting, are invited to submit an abstract for consideration by the Scientific Committee.

Abstracts must describe original work, previously unpublished and not yet presented, at the time of the submission.

Scheduling of e-poster sessions and abstract presentations is at the discretion of the Scientific Committee.

The abstracts will be peer-reviewed and those selected will be presented either as oral presentations or in the e-poster session.

For standardization, the acceptable length of the abstract is of maximum 2500 characters. This includes the titles and non-visible characters, such as spaces and line breaks.

Abstract submitters will be asked their professional category during the submission process. Nurses, physiotherapists and psychosocial professionals will have the opportunity to display their e-posters during the Allied Health Professionals Day as well as during the Virtual Congress.

  • 6 abstracts will be selected by the Scientific Committee to be presented orally in the SLAM session. Kindly note that the selection for these oral presentations is based on the scientific calibre of the abstract and its coherence with the other selected abstracts.
  • EAHAD would like to promote young scientists in the SLAM session. Accordingly, if you wish to submit an abstract for an oral presentation, you will be asked to confirm that the presenting author will be 40 years old or under at the time of the congress.

The internet abstract submission system works best with Chrome: 16 or higher, Internet Explorer 8.0 or higher and Mozilla Firefox 5.0 or higher.

    • Discussions / Conclusions should provide only conclusions of the study directly supported by the results, along with implications for clinical practice, avoiding speculation and overgeneralization.
    • No tables or figures are allowed in the abstract.
  • Conflict of interest: It is the intent of EAHAD 2021 to provide high-quality sessions focused on educational content that is free from commercial influence or bias. Thus, the submitting author of an abstract is requested to declare any potential conflicts of interest for all authors during abstract submission.

The session room is equipped with:

  • Data projector for PowerPoint™ presentations
  • Laptop (no Macintosh™)
  • Clip microphone (main rooms only)
  • Lectern microphone
  • Laser pointer


  • Use Microsoft PowerPoint™ version 2010.
  • Video files must be integrated in your PowerPoint™ presentation.
  • Use screen resolution 16:9 otherwise we will not be able to show your presentation (you will find instructions below on how to prepare your presentation in 16:9). Do not forget to add the Conflict of Interest slide available on the website.
  • Please bring a USB with your presentation (Microsoft PowerPoint™ version 2010) to the technician at the Speakers’ Preview Room at least one-half day before the start of the session during which you will give your presentation.
  • When you use PowerPoint™ always use the option: ‘Font TrueType’.
  • If you use a Mac/Macintosh™,  computer, save your presentation on a PC format.
  • Keynote presentations (Mac/Macintosh™ hardware) are not compatible and cannot be used!



  • Plan your presentation carefully.
  • Co-ordinate each phase of your lecture with your PowerPoint™ slides.
  • Number the sheets at the bottom of the page, and have them in proper order and position.
  • Avoid unfamiliar abbreviations or expressions.
  • Your text should be highly legible, double or triple-spaced, with well-marked cues for slides.
  • For PowerPoint™ slides, a coloured background usually works better than black and white. However, colours should be kept limited and simple.
  • Optimise the visual simplicity of your slides – use few words and avoid sentences.
  • Try not to use more than 6 bullet points per slide.
  • Leave out text you do not plan to discuss.
  • Use several slides to cover a detailed topic that cannot be logically included in one slide.
  • If you must refer to one slide on several occasions during your presentation, use duplicates instead of trying to return to the original.
  • Graphs often speak louder than words.


  1. Introduce your topic and inform your audience what you intend to speak about.
  2. Deliver your talk, including the methods, results and conclusions.
  3. Summarise the most important points of your lecture for the audience.


Note: The sessions will not have simultaneous interpretation. Please be aware that some participants may not have English as their mother tongue. For that purpose, please remember to speak slowly and clearly.



  • Bring a text prepared specifically for the oral presentation.
  • Find time before sessions begin to acquaint yourself with the operation of the podium and location of the equipment. Conference staff will be present to assist you.
  • Give the technician any special instructions you may have before, not during the talk.
  • Be careful to speak in accordance with your slide sequence. Discuss the material as written on the slides.
  • Use a laser pointer to guide the audience. Do not wave the pointer around the slide.
  • Remember to speak slowly and clearly.
  • Please stay within the time limit allocated for your presentation.


Open PowerPoint™ and go under Design:

Then under page Setup:

Finally on “Slides sized for” select “On-screen Show (16:09) on the drop down list:


  • It is mandatory to indicate poster number in the upper right corner of the poster
  • The usable poster board surface is 100 cm wide by 125 cm high (portrait format).
  • Don’t overload your poster. Remember, you are not writing an article.
  • Seek simplicity, keep text to a minimum and avoid redundancies.
  • Use 500 to 1000 words (including title, figure legends and tables), not more.
  • The figures and tables should cover approximately 50% of the poster area.
  • Prepare a 15 cm high title strip that runs the full width of the poster. Use a black and bold typeface, not smaller than 30 mm in height for the title and at least 20 mm for authors’ names and affiliations (the height refers to capital and tall letters), Capital letters are usually more difficult to read than small letters.
  • The average reader spends 1-2 minutes on your poster. Highlight your main finding. Most of us start by reading the Conclusions. Thus, don’t hide them in the right lower corner. Put them at eye level, either at the top of the right column or, alternatively, start with the Conclusions. Otherwise, structure your poster by Introduction, Methods and Results. State your aims at the end of the introduction.
  • We suggest that the pathway (eye movement) be downward. Use 3-5 columns.
  • The poster is supposed to be readable from a distance of 1.5-2 m. The text should definitely be no less than 5 mm for capitals and tall letters, preferably larger. Use the same font throughout the poster.
  • Let your important points stand out. Use (but don’t overuse) bold and colours.
  • If possible, avoid abbreviations and acronyms, especially in the Conclusions.
  • Feel free to provide one or more key references (in the right lower corner).
  • Handouts of your abstract / poster (with your email addresses) for your interested readers may facilitate future research communication.
