7.3 GPCAP 2026: Congress Abstracts, Presentations & Encores
Key Takeaways
GPCAP 2026 is the current principle-based reference for pharmaceutical-supported conference abstracts and presentations and is aligned with GPP 2022 and current ICMJE recommendations.
The individual conference's instructions control deadlines, abstract categories, word or character limits, author limits, layouts, disclosures, embargoes, encore rules, and presentation formats.
Authorship and contributorship should be accurate and transparent, with all listed authors able to review and approve within the conference timeline and writer support disclosed.
Conference materials must accurately represent the research, distinguish prespecified from exploratory work, report important limitations and harms, and remain non-promotional.
Accessibility, inclusivity, patient engagement, enhanced content, responsible AI use, copyright, citations, and encore transparency are explicit current considerations.
GPCAP 2026: Congress Abstracts, Presentations & Encores
Note
The Good Practice for Conference Abstracts and Presentations (GPCAP) recommendations: 2026 update is the current principle-based reference for pharmaceutical-supported conference materials. It aligns with GPP 2022 and current ICMJE recommendations, while recognizing that each conference's instructions take precedence for its own submission and presentation process.
Why Conference Publications Need Specific Controls
Conferences disseminate new findings quickly, often before a full manuscript is available. Short deadlines, strict space limits, evolving data, presenter availability, and multiple formats create risks that differ from journal publication. GPCAP promotes transparency, consistency, practicality, integrity, and accessibility across:
- abstracts;
- posters and digital posters;
- oral presentations;
- enhanced content;
- encore presentations;
- materials developed with professional writing or design support.
GPCAP does not supply one universal abstract word limit, poster template, slide sequence, or deadline. Those are venue rules.
Begin with the Conference Instructions
At project initiation, download and archive the current instructions. Record:
| Control | What to verify |
|---|---|
| Submission deadline and time zone | Exact cutoff and whether edits remain possible |
| Abstract category | Original research, trial in progress, late breaking, encore, case report, or other venue-defined category |
| Length and structure | Word or character count, headings, tables, figures, and reference rules |
| Author and presenter rules | Eligibility, limits, memberships, approvals, substitutions, registration |
| Disclosure fields | Funding, conflicts, writing support, sponsor role, AI declarations if requested |
| Presentation format | Poster dimensions, e-poster file, slide ratio, duration, accessibility requirements |
| Embargo and publicity | When data may be discussed publicly or with media |
| Copyright and licensing | Ownership, reuse, permissions, conference posting |
| Encore policy | Prior-presentation disclosure, permitted changes, geographic or audience conditions |
Do not assume that a late-breaking category permits placeholder results. Some venues require complete results at submission; others define special update procedures. The submitted abstract must satisfy the actual policy.
Authorship and Contributions
GPCAP 2026 says conference authorship should aim to follow current ICMJE and GPP principles, but acknowledges conference-specific requirements and practical constraints. Conferences may require a society member, local-language presenter, or a limit on named authors. These rules must be handled transparently rather than by silently adding or deleting people.
Before submission:
- identify contributors early;
- communicate the venue criteria and schedule;
- give listed authors a meaningful opportunity to review and approve;
- confirm presenter willingness and availability;
- record contributions and approvals;
- recognize nonauthor contributors and professional writing support according to applicable requirements.
An individual who cannot review or approve in the available timeline may choose not to be listed on that conference output even if they could qualify for a later full manuscript. Document the decision. Do not promise future manuscript authorship automatically; reassess against the criteria for that work.
Abstract Content
An abstract should accurately state:
- the question and relevant design;
- participant or data source;
- interventions or exposures;
- prespecified outcomes and analysis;
- numerical results available at submission;
- important harms or limitations;
- a conclusion proportionate to the data;
- registration, funding, and disclosures as required.
Do not present an exploratory analysis as a prespecified primary result. Avoid “safe,” “effective,” or “well tolerated” without adequate evidence and context. If data change after submission, use only the conference's authorized correction or update process and ensure the presentation explains material differences.
Trial-in-progress abstracts should not imply outcome findings that are not yet available. Late-breaking status is a venue classification, not a general exemption from accuracy or author approval.
Posters and Oral Presentations
A poster or slide deck should be consistent with the accepted abstract while providing the detail and context the format allows. Report denominators, uncertainty, limitations, and harms. Cite sources and obtain permissions for reused material.
Design should support comprehension:
- readable text and labels;
- sufficient color contrast;
- graphics that remain interpretable without color alone;
- clear legends and data sources;
- alternative or enhanced formats where the venue supports them;
- plain-language elements appropriate to the audience.
There is no universal rule that posters must contain a fixed percentage of white space or that disclosures must always appear on “slide 2.” Follow venue placement rules and make disclosures readily visible.
The presenting author is responsible for the scientific presentation and discussion. Professional writers, designers, statisticians, and sponsor teams may support development within disclosed, ethical roles; they should not create undisclosed ghost authorship or transform scientific exchange into promotion.
Accessibility, Inclusivity, and Patient Engagement
GPCAP 2026 adds explicit attention to accessibility and inclusivity. Consider people with visual, auditory, motor, language, and neurocognitive needs. Where suitable and permitted, enhanced content may include plain-language text, audio, video, captions, transcripts, translations, or accessible digital versions.
Patient or caregiver involvement should be purposeful, fairly recognized, and governed by clear expectations. Compensation for legitimate work may be appropriate under policy and law and does not automatically disqualify authorship. Accessibility is not achieved merely by reducing scientific accuracy; explain technical concepts in a usable form while preserving the data.
Artificial Intelligence
If AI tools assist with drafting, translation, image creation, summarization, or editing, apply the current conference, employer, and journal policies. AI is not an author because it cannot take responsibility or accountability. Human authors remain responsible for accuracy, confidentiality, permissions, bias, originality, and disclosure.
Do not place confidential or personal data into an unapproved system. Verify generated citations, text, images, and numerical statements. Disclose use when the venue or applicable policy requires it.
Embargoes, Publicity, and Non-Promotional Conduct
An embargo controls when accepted findings may be publicly released. It is distinct from author review, regulatory review, and copyright. Coordinate press activity, investor communications, social media, and sponsor channels with the conference's current policy.
Scientific conference materials should be accurate, balanced, and non-promotional. Branding, links, QR codes, and supplementary resources must comply with the venue and applicable regional rules. A QR code is not inherently acceptable or prohibited; evaluate its destination, content, accessibility, data collection, durability, and venue permission.
Encore Presentations
An encore presents substantially the same findings to another audience. Whether it is allowed depends on both the original and receiving venues, copyright or license terms, and applicable policy. A compliant process asks:
- Does the receiving conference permit encores?
- Must prior presentation details be disclosed?
- Does the original conference or publisher control reuse?
- Are translations or local adaptations allowed?
- Have data changed, and if so, is the output still an encore or a new analysis?
- Are author approval and disclosures current?
Clearly identify prior presentation when required. Obtain permissions for copyrighted text, figures, or layouts. Do not label a materially new analysis as an encore merely to bypass originality or submission rules.
Operational Timeline
Work backward from the actual deadline:
- confirm category, data maturity, and authors;
- draft from validated analyses;
- conduct author and required sponsor reviews;
- secure final author approval;
- complete disclosures and submit;
- archive the submitted version and confirmation;
- build the poster or slides from the accepted content;
- revalidate updated data and document changes;
- obtain presenter approval and rehearse;
- archive final presented materials and evidence of disclosure.
The timeline must reflect the venue and organization; GPCAP does not impose a universal number of weeks.
Important
Treat GPCAP 2026 as the current baseline and the conference instructions as the operational rulebook. Never substitute generic claims—fixed word limits, mandatory placeholders, a required disclosure slide number, or universal encore permission—for the actual venue policy.
A team plans a late-breaking abstract but does not yet have final results. What should the publication professional do first?
Check the specific conference's late-breaking criteria and update policy before deciding whether the data are eligible
Insert placeholder results because all late-breaking categories allow updates
Submit a promotional conclusion without numbers
Use the word encore to avoid the data requirement
Which statement about congress presentation format is most accurate?
Every poster must contain 50% white space
Every oral presentation must put disclosures on slide 2
Venue instructions control format and placement, while disclosures must remain clear and accessibility should be considered
GPCAP prohibits all QR codes
Before submitting an encore presentation, which review is essential?
Only whether the sponsor prefers the new venue
Receiving-venue policy, prior-presentation disclosure, copyright or license terms, data changes, and current author approval
Whether the abstract can omit funding because it was disclosed once before
Whether a new title can conceal the prior presentation
