CROI poster presenting authors illustrate their study findings by displaying graphs, figures, diagrams, and text that describes their main findings, background, methods, results, and conclusions on posters that are available in the poster hall throughout the conference. Poster sessions afford an opportunity for presenters to engage attendees in a rich discussion of their research during a 1.5-hour session at CROI. Poster presenters also submit a digital version of their poster, which serves as an educational resource after the conference.

Poster Design

Posters should be designed to attract interested attendees by quickly focusing them on the main findings of the study. We suggest a design similar to one pictured below.

CROI Conference - CROI Poster Template

Presenters may download a template in this optional design in this PowerPoint slide. The slide notes contain a poster development guide that includes formatting notes (eg, font size, use of color, poster print size) and poster content requirements (eg, poster number and no QR codes).

Poster Title: The poster title should be the same as the title submitted with the abstract and appear in boldface at the top in either all capital letters or standard American Medical Association (AMA) title case (Nouns, pronouns, verbs, and other important words begin with uppercase letters; coordinating conjunctions, articles, and prepositions of 3 letters or fewer should all be in lowercase letters unless they are the first or last words in a title or subtitle).

Poster Number: The poster number should be displayed in the upper right corner (“0000” in the Alternate Poster Design template). This is not the abstract submission number assigned during submission of the abstract, but a number which notes the position of the poster in the poster hall and in the conference program. This number will be sent to the presenting author after late-breaking abstracts have been accepted in January.

QR Codes Are Not Allowed: Please note that QR codes or bar codes are not permitted on posters displayed at CROI or on electronic versions of the posters to be uploaded to the CROI website.

Poster Videos

Poster presenters have the opportunity to upload an up to 5-minute video description of their research prior to CROI. Poster presenter videos will be available to attendees during the conference via the CROI Mobile App, and available to the public as an educational resource on the CROI website after the conference.

Video Content: Poster presenter videos should (1) place the study in context with the field through a brief background, (2) briefly summarize the methods used in the study, (3) highlight important data and key results, and (4) focus primarily on important conclusions and the implications for future research.

Poster Video Submission: Video upload instructions will be sent to poster presenting authors prior to CROI.

Electronic Posters

Poster presenters are required to upload an electronic version of their final poster as a PDF file prior to the conference. The electronic poster will be available to attendees at the conference via the Mobile App and to the public after CROI.

Electronic Poster Submission: An email notification will be sent to poster presenting authors when electronic poster submission opens. Presenters will log in to the CROI Abstract Website and access their schedule from the Dashboard, then, click the Upload Presentation button by the poster presentation listing.

Electronic Poster File Format: Please save the poster as a PDF (in the smallest file size possible). Other file types are not supported.

Presenting Author Responsibilities

The presenting author is responsible for presenting the abstract at the conference and must be present at the poster during the entire session. If exigent circumstances require presentation by an alternate coauthor named on the abstract, please contact CROI immediately by email at

Requirements for Presentation Development

Presentations from randomized trials and cohorts should follow the International Committee of Medical Journal Editors (ICMJE) guidelines, including reporting of study designs, (eg, prospective, observational, randomized, double-blind, STROBE, CONSORT, or others), statistical methods, and outcomes by demographic variables. See the ICMJE guidelines for more details.

Appropriate information and correct terminology should be used with regard to sex and gender. For human clinical or epidemiological studies, sex-stratified results should be provided or who was included if it includes only a single population. Appropriate terminology such as cisgender (people whose gender match the sex assigned at birth) or transgender (people whose gender does not match the sex assigned at birth) should be used. Both sex and gender data should be provided in the presentation. Presentations of preclinical data including the use of cell lines and animal studies should include the sex of the animals or the sex of the source of the cell lines. If data are not available on sex and gender, this should be identified as a limitation in the presentation.

Out of respect for their contributions to our scientific advances, avoid calling study volunteers “subjects.” The preferred terms are study “participants” or “volunteers.”

Please also note whether the study is ongoing or completed and whether the results are preliminary or final.

Publication or Presentation Prior to CROI

If study data are accepted for publication or presentation after the abstract submission to CROI, and that publication or presentation is expected to take place before CROI, the presenting author must contact CROI at to provide details as soon as the presentation is accepted for review, presentation, or publication in another venue or outlet. Please be aware that, although publication in these circumstances will not necessarily prevent presentation of the research at CROI, our strong preference is that any additional publication or presentation happen either simultaneous to or following presentation at CROI. Requests to publish or present research accepted for presentation at CROI prior to its presentation at CROI will be evaluated on a case-by-case basis. Failure to notify the conference promptly regarding plans to publish or present a CROI-accepted abstract prior to CROI may result in the removal of the study from the conference program.

Displaying Posters at CROI

The suggested size for posters is either 54 inches (width) x 36 inches (height) or 60 inches x 40 inches (137.2 cm x 91.4 cm or 152.4 cm x 101.6) based on the CROI Poster Template. The minimum size for a poster is 36 inches (width) x 24 inches (height) so attendees can see the poster at a minimum of 10 feet away.

Maximum Size: The size of the board for displaying the poster is 96 inches (width) x 48 inches (height). The maximum size of a poster is 93 inches (width) x 45 inches (height).

The face of the poster board is covered with Velcro-receptive fabric. Pushpins will be provided to hang posters.

Poster Printing

Presenting authors should print their physical poster based on the requirements listed in the sections above. CROI does not print posters on behalf of presenters.
