Abstract Submission

The 22nd IWHOD will open to submissions on 3rd November 2017.

You can register before submissions open at the following link:


The maximum number of abstracts each cohort or cohort collaboration can submit is SIX. At most FOUR abstracts per cohort will be accepted (resulting in a maximum of FOUR persons per cohort). 

Purely methodological abstracts (which might use example data from a cohort) do not count as one of the six submissions for that cohort. At most TWO methodological abstracts can be submitted by one person.

Abstracts of studies that will be presented AT CROI 2018 are INELIGLIBLE for submission to IWHOD. Any abstract accepted for CROI 2018 as a Late Breaker must be withdrawn from IWHOD . Please make sure to let the secretariat (secretariat@IWHOD.org) know of any abstract accepted by CROI as soon as notified.

Abstracts presented at IWHOD 2018 may be submitted to future conferences or workshops occurring after March 2018, or submitted to journals for publication after being presented at IWHOD.



Your abstract must be submitted via the web-link you will find on the TOP of this page. You will be asked to register with the system. Please then carefully follow the instructions on that page.

    1. Your abstract must not exceed 500 words (including tables and figures).
    2. A maximum of one display item (figure, graphic or table) is allowed - these must include a TITLE. Colour images are allowed.
    3. Please follow the general outline Background, Methods, Results and Conclusion where applicable. 
  • Please note that the abstract submision system will support a maximum of 15 authors for one abstract.
  • If the cohort your abstract is associated with is not on the cohort dropdown list on the online submission page please select “other” on the list and specify the name of your cohort in the designated field. 
  • If you wish to add the name of your cohort to the authorship of your abstract please tick the option on the online submission page (at the bottom of submission form, page 1)
  • If you are submitting an abstract on behalf of a multi-cohort collaboration and want all cohorts/collaborations to be acknowledged in the authorship please select “other” in the cohort dropdown list of the online submission page and specify the name of the cohorts in the designated field (e.g. CASCADE, UK Register and UK CHIC).


Authors will be asked to enter their cohort profile upon submission of their abstract:

  • If your cohort is submitting multiple abstracts, please agree the cohort description with your colleagues before completing the cohort profile section, ensuring that you enter one identical cohort description for all abstracts submitted. The information requested from the cohorts is as follows: the full name, cohort acronym, principal investigator, brief cohort description (max 100 words), link to study website.
  • When submitting purely methodological abstracts, you may select “methodology” in the appropriate field on the online submission page and enter N/A in the cohort description fields so you are able to complete your submission.
  • If your abstract is submitted on behalf of a multi-cohort collaboration (e.g. CASCADE, UK Register and UK CHIC) you will need to decide which cohort you want to provide a description for as only one cohort profile per abstract can be entered on the online submission page – this is up to the author and cohort PIs. If appropriate, it is also possible to combine separate cohort descriptions for a multi-cohort collaboration into one by giving information on how the collaboration came together and a short description of each cohorts in the designated cohort profile fields on the online submission page.

Please contact the secretariat@IWHOD.org if you have any further queries.
