Put a Conference Poster in Evidence Context

A clinician catches you after a session, phone in hand, showing you a photo of a poster from last month's congress. They already have a take on what it means, and that take usually runs ahead of what the poster can actually support. Your job in that moment is not to confirm the claim or shut it down. Your job is to help the clinician see the poster for what it is, an early piece of work, and walk through what it shows and what it leaves open.

Why this conversation goes wrong

Conference posters carry a strange kind of authority. They look finished. They have charts, a methods section, a conclusion in bold type at the bottom. But a poster is often the first public airing of a small study, sometimes with a limited sample, a short follow up period, or an analysis that has not gone through peer review. Clinicians see the poster once, at a crowded session or in a photo a colleague sent them, and they remember the headline number more than the caveats printed in size eight font at the corner.

This creates two failure modes for a medical science liaison. The first is agreeing too quickly. If you nod along with the clinician's excitement, you are effectively vouching for a conclusion the data may not support yet. The second is shutting the conversation down too hard. If you respond with a flat warning about preliminary data, you come across as dismissive of something the clinician found genuinely interesting, and you lose the chance to have a real scientific conversation with them. Neither response serves the clinician or the patient behind the question.

How to prepare

Before you respond to a poster claim, get the actual poster, not a summary of it. A photo taken from three rows back tells you almost nothing about sample size, comparator arm, or statistical method. Ask the clinician to send it, or pull it yourself from the congress abstract database if it is available. Read the methods section closely, not just the conclusion.

Check whether the abstract behind the poster has been indexed anywhere else, and whether the authors have said anything about a fuller manuscript being under review. Note the population studied, since posters at congresses often report enriched subgroups that do not map cleanly onto the patients a clinician sees. Write down the study's own stated limitations. Most posters include a line or two about sample size, missing data, or follow up duration, and that line is often the most useful thing you can bring into the conversation.

Also decide ahead of time where the conversation needs to stop. If a clinician's question drifts toward changing a treatment protocol or making an off label comparison, you need a clear line for redirecting to the right channel, whether that is a medical information request or a formal literature review. Knowing that line before the conversation starts keeps you from improvising it under pressure.

What to say

The clinician opens with confidence. "Everyone at the session was talking about this poster. Sounds like it changes how we should be dosing."

You do not argue with their enthusiasm, and you do not accept the conclusion either. "I can see why it got attention, the numbers on the slide were striking. A poster gives us a different level of detail than a full publication, usually less. Do you have the full poster, or just what came up on the screen? I'd like to walk through the methods and see what the authors said about the study's limits before we talk about what it might mean for practice."

The clinician says they only saw it briefly, but they remember the effect size looked large. You follow with a specific question rather than a broad reassurance. "That's worth pulling the source material for. Once we have it, I want to look at how they handled the comparator arm and whether there was missing data in the follow up period, since that changes how much weight the effect size can carry. Can I send that over once I've reviewed it, so we're looking at the same document?"

The clinician agrees and adds a real question of their own, asking whether the study population matches the patients they treat. That is the conversation you want. You have not confirmed the poster changes anything, and you have not brushed off a clinician who is genuinely engaged. You have moved the discussion from a secondhand impression to the actual source, with specific questions attached to it.

Mistakes to avoid

Do not treat the poster's conclusion as settled just because the clinician is excited about it. Enthusiasm is not evidence, and repeating a poster's own bold conclusion back to a clinician without qualification puts you in the position of endorsing preliminary work as practice guidance.

Do not guess at numbers or methods you have not actually seen. If you have only seen a photo or heard a secondhand summary, say so plainly and get the real document before you comment on specifics. Filling in gaps from memory or assumption is how small errors turn into larger ones as the conversation gets repeated.

Do not promise a peer reviewed publication is coming if you do not know that for certain. Authors sometimes never publish beyond the poster, and telling a clinician to expect a paper that never arrives damages your credibility later.

Do not let the conversation slide into discussing off label use or protocol changes based on the poster alone. If the clinician pushes in that direction, redirect them to the appropriate internal process rather than answering informally, even if you feel confident about the science.

If you want to see how a related conversation plays out before the poster even reaches a full study, read Put a Congress Abstract in Scientific Contextwhich covers the same evidence discipline applied to an abstract earlier in its life. For what happens after this exchange, once the clinician has the source material in hand, see Follow Up on a Congress Poster With Evidence Maturity in View.

How to practice and score it

This conversation is easy to describe and hard to do well under real pressure, especially when a clinician is animated and time is short. Practice it with a colleague who plays the clinician and comes in with a strong, slightly overstated claim about a poster, the same way a real clinician would after a busy congress session. Run the exchange twice, once where the colleague pushes back with follow up questions about the study design, and once where they simply want agreement.

Score the practice on three things. Did you acknowledge the clinician's interest without confirming the conclusion. Did you name specific elements of study design, sample size, comparator, missing data, follow up length, rather than speaking in general terms about preliminary evidence. Did you offer a concrete next step, sending the source material, scheduling time to review methods together, rather than leaving the conversation as a vague promise to look into it.

A tool like DealSpeak can run this scenario with an AI clinician that varies its pushback each time, so you are not just rehearsing the same script with the same colleague. The record from that session should show the poster clearly identified, the specific scientific questions raised, and a plan for follow up, all kept separate from any statement about changing patient care.

What this comes down to

A poster is a starting point for a scientific conversation, not an endpoint for a clinical decision. Handle the clinician's interest with respect, handle the data with rigor, and keep those two things from blurring together. If you want more scenarios like this one built around real MSL conversations, the Pharmaceuticals practice conversations library has more to work through.
