Please carefully read the following guidelines and sample abstract prior to submitting an abstract online

Abstract submission guidelines

  • The abstracts must not have been published Note that selected abstracts will be published as a supplement in Haemophiliajournal, the official Congress book of abstracts.
  • All presenting authors must be paid registrants of the WFH 2022 World Congress by February 7,2022, for regular abstracts and by March 31, 2022, for late-breaking abstracts. After this date, presenting authors who have not paid their registration fees will be excluded from the program, as well as from the Book of Abstracts.
  • The submission of an abstract carries with it the obligation that it will be presented at Congress by the presenting author. Failure to present as scheduled may result in the non-acceptance of future submissions at WFH meetings.
  • Each abstract will be blinded and scored by three reviewers. Abstracts will be accepted based on the following criteria: relevance; interpretation of results; originality and novelty; organization; and clarity.
  • Rule of two: Each author may present a maximum of two abstracts at the Congress. However, authors can make an unlimited number of submissions. Should an author have more than two abstracts accepted, a co-author must be named as the presenting author for the third or more abstracts.
  • Abstracts may not be revised or resubmitted after the deadline date of December 3, 2021
  • Please submit abstract withdrawal requests in writing by February 25, 2022
  • Please submit change of presenting author requests in writing by February 28, 2022. After this date, changes will not appear in the Book of Abstracts.

By submitting an abstract, you consent to the following:

  • If accepted, your abstract may be published in the Haemophilia journal supplement
  • If accepted as an oral presentation, your presentation may be posted on the WFH website, on-site and post-Congress
  • If accepted as a poster presentation, you will display your poster at the Congress
  • Abstracts should be clear, concise, and written and presented in English. Abstracts will be published as submitted. Presenters are requested to carefully proofread their abstract. The Congress Program Committee reserves the right to reject abstracts that are deemed to be poorly written or to request an immediate revision of the text to improve its readability.
  • Abstracts should not exceed 350 words. When calculating your word count, please note that every table or graph in your abstract counts as 50 words each.
  • Images are NOT permitted
  • Be sure to select the appropriate topic category when submitting your abstract to ensure proper consideration. The Program Committee reserves the right to move abstracts to other subjects as they see fit, as well as to add and remove categories as required.
  • Select a preferred presentation type (oral or poster). The Congress Program Committee will determine whether the abstract will be accepted as a free paper, moderated poster, or a poster, with consideration given to the author’s preference, available time, and fit in the Congress program.
  • Your abstract must include the following sections:
    • Introduction and objective
    • Materials and methods
    • Results
    • Conclusions
  • Do NOT include references, credits, or grant support in your abstract
  • Authors and affiliations are to be submitted using the on-line form only. Only one presenting author is permitted per submission.
  • If an author’s name appears on more than one abstract, it must be written in the same way on each abstract to ensure proper indexing
  • Abstracts that describe single clinical cases or lack quantitative data will NOT be accepted. Authors are not to split data to create several abstracts from one. If “splitting” has been judged to have occurred, the priority scores of related abstracts will be reduced.
  • During the abstract process, you will be asked to enter author information and affiliations. Please list the authors in your preferred citation order. If you are submitting supporting graphs or tables, please do not include the author list in the Word document, as we operate by blind review.
  • Use a short, specific title. The title should be entered in sentence case. Do not use a period at the end of the title.
  • Capitalize the first letter of trade names
  • Do NOT use ALL CAPS in the title or in the body text
  • Use standard abbreviations for units of measure; other abbreviations should be spelled out in full at first mention, followed by the abbreviation in parenthesis (exceptions: RNA, DNA, etc.)
  • Special characters: please use the special character palette if you need to use a special character. If you copy and paste your abstract, please be sure to enter special characters using the palette, even if they seem to appear correctly after pasting. If you do not use the special palette, your special characters will not appear properly in publication. Please be sure to double-check during the proofreading step to ensure all special characters were converted properly.

The notification of abstract acceptance or rejection for early abstract submissions will be sent the week of January 10, 2022.

The notification regarding abstract status—as either a free paper or poster presentation—as well as presentation guidelines will be sent during the week of January 10, 2022.

The notification for late-breaking abstracts will be sent the week of March 21, 2022.

Please note that only the corresponding author will be contacted concerning the abstract, and thus the corresponding author is responsible for informing all co-authors of the status of the abstract.

If an author or immediate family member has had a substantial financial relationship relating to the support of the abstract, this relationship must be disclosed. Such relationships include salaries, ownership, equity positions, stock options, royalties, consulting fees and honoraria for speaking, material support and other financial arrangements. During the abstract submission process, you will be asked to disclose any potential conflicts of interest.

The call for late-breaking abstracts opens February 2, 2022. The submission deadline is March 2, 2022, at 11:59 p.m. ET. The status of the peer review will be announced the week of March 21, 2022.
