Poster Presentation Guidelines

A poster session is a graphic presentation of an author's research. Authors illustrate their study findings by displaying graphs, photos, diagrams, and a small amount of text on poster boards.

Updated for CROI 2018. Presentations from randomized trials and cohorts should follow the 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: ICMJE Preparing for Submission.

Of particular note, please consider whether there is substantive evidence of differences in effect by sex or other key demographic groups. If so, a stratified analysis should be made available during the presentation of the abstract at CROI. Please also note whether the study is ongoing or completed and whether the results are preliminary or final.

Electronic Poster Requirement

Electronic poster submission will begin on January 25, 2018. To upload the final version of your electronic poster, log in to the CROI Abstract Website and follow the instructions in My Ready Room. In order for CROI attendees to view posters during the conference, please submit the final version of the electronic poster by February 26, 2018. Electronic posters will be available to the public after CROI.
Note: Please save the poster as a PDF in the smallest file size possible. Other file types are not supported.


The poster boards are 4 feet (48 inches) by 8 feet (96 inches) long landscape orientation. The useable area of the poster board is 45 inches by 93 inches and is the maximum recommended size for the poster boards. The minimum size recommended is 24 inches by 36 inches so attendees can see the poster at a minimum of 10 feet away. The face of the poster board is covered with Velcro receptive fabric. Push pins will be provided for your poster.

Poster Dimensions

Format and Required Information

Poster material should be well labeled and legible from a distance of 10 to 15 feet. The title should be the same as the title submitted with the abstract and appear in boldface at the top. For additional text, use 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. 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 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.

Poster Presenters

Poster presenters must supply an electronic version of their posters prior to the start of CROI to receive credentials for Poster Hall access. Please load your poster on to a portable drive. Posters should be submitted as a PDF or PowerPoint file. Please rename your file with your abstract number (eg, if your abstract number is 1234, save the file as 1234). The electronic version will be posted on the CROI website.

On your designated board you will find all the materials needed for mounting your poster (poster number and thumb tacks).
