Abstract Submission

The 21st IWHOD abstract submission site is now open. Please click the following link to submit your abstract.

 Make sure to read the guidelines below before submitting to IWHOD.

Deadline for submitting abstracts: Monday 5 December 2016 18:00 GMT (UK time).


Invitations to attend the workshop apply to the presenting author of accepted abstracts. Please read the abstract submission rules below.

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 2017 are INELIGLIBLE for submission to IWHOD. Any abstract accepted FOR CROI 2017 as a Late Breaker MUST BE WITHDRAWN from IWHOD. Please make sure to let the secretariat know of any abstract accepted by CROI as soon as notified.

Abstract Submission Rules

  • Your abstract must be submitted via the IWHOD online abstract submission system. 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.
  • Abstracts must be submitted using the approved ABSTRACT SUBMISSION FORM which will be sent to you in your registration confirmation email. Your abstract body must fit into the space provided on the abstract submission form and must not exceed 500 words (including tables and figures). A maximum of one display item (figure, graphic or table) is allowed and must be titled. Your abstract must use Arial 10 and single line spacing.
  • When submitting purely methodological abstracts, you may select “methodology” in the appropriate field on the author online submission form rather than give details of your cohort.
  • Please note the abstract submission system will support a maximum of 15 authors for one abstract.
  • Please follow the general outline: Background, Methods, Results and Conclusion where applicable.

To help you visualise what is possible to fit into the space provided on the abstract submission form we have created the following three examples. Please refer to them when preparing your submission:

- Example of an abstract with a table

- Example of an abstract with a figure

- Example of an abstract with maximum number of words (500)

Cohort Profile

Authors will be asked to enter their cohort profile upon submission of their abstract. Please use the following guidelines:

  • If your cohort is submitting multiple abstracts, please agree the cohort description with your colleagues before completing the cohort profile section. Ensure that you enter identical cohort descriptions 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, principle investigator, contact details, brief cohort description (max 100 words), link to study website
  • If the cohort your abstract is associated with is not on the drop-down list please select “other” 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 just above the section for abstract upload. The cohort name will then appear at the end of authorship preceded by “on behalf of“ in the abstract book.
  • When submitting purely methodological abstracts, you may select “methodology” in the appropriate field and enter N/A in the cohort description fields so you are able to complete your submission.
  • 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 drop-down list and specify the name of the cohorts in the designated field (e.g. CASCADE, UK Register and UK CHIC).

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