Abstract Submission


The abstract submission system can be found at: https://app.oxfordabstracts.com/stages/1172/submissions/new.

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 which will be presented at CROI 2020 are INELIGLIBLE for submission to the IWHOD Workshop. Any abstract accepted FOR CROI 2020 as a Late Breaker MUST BE WITHDRAWN from the IWHOD Workshop. Please make sure to let the secretariat ( IWHODSecretariat@ucl.ac.uk ) know of any abstract accepted by CROI as soon as notified.


  • Your abstract must be submitted via the web-link you will find on the top of this page. First, you will be asked to register with the system and create a user name and a password which you will need to log on the online submission page. Please then carefully follow the instruction on that page.
    1. Your abstract body must fit into the space provided on the abstract submission form and must not exceed 500 words (including tables and figures).
    2. A maximum of one display item (figure, graphic or table) is allowed - these must be accompanied by a TITLE. The display item must be LEGIBLE on the form. Colour images are permitted.
    3. Please follow the general outline Background, Methods, Results and Conclusion where applicable
  • Please note that the abstract submission system will support a maximum of 15 authors for one abstract.
  • 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 you are a returning cohort that appears on the drop-down list and would like to use the cohort description from a previous IWHOD then please enter “Use 2019 IWHOD details” or similar in your cohort description. Please only do this if you are sure there are no updates to your prior cohort entry
  • If your cohort is submitting multiple abstracts, please agree the cohort description with your colleagues before completing the cohort profile section on the online submission page ensuring that you enter one identical cohort description for all abstracts submitted on behalf of the same cohort. The information requested from the cohorts is as follows: the full cohort name, cohort acronym, principal investigator, contact details, 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 (e.g. the CASCADE, UK Register and UK CHIC collaboration) 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  IWHODSecretariat@ucl.ac.uk if you have any further queries.
