How to Present Clinical Data on a Medical Poster
Show clinical outcomes with denominators, time points, effect sizes, uncertainty, and limitations instead of dense manuscript tables.

Give each panel one clinical question
A baseline panel establishes context, an outcome panel shows magnitude and uncertainty, and a safety panel reveals harms. Keep these roles distinct. One chart carrying population, time, outcome, subgroup, and treatment simultaneously hides the important comparison.
- Name the summary statistic.
- Include analysis populations.
- Keep treatment labels consistent.
Make time and denominator visible
Interpretation often turns on when measurement occurred and who remained. Put time points on the axis, show denominators at visits, and distinguish missing observations from zero events. Explain differing follow-up windows near the plot.
- Label baseline and follow-up.
- Report attrition.
- Do not imply unmeasured continuity.
Conclude at the evidence level
Use causal language only when supported. Observational associations, underpowered estimates, surrogate outcomes, and exploratory subgroups need careful wording. Pair the main conclusion with effect size, interval, and the limitation most likely to alter a clinical decision.
- Match verbs to design.
- Separate significance from importance.
- Obtain statistical and clinical approval.
A practical example
For 30-day readmission, show events over eligible participants in both groups, the absolute difference with interval, and a compact attrition note instead of a tiny spreadsheet.
Rebuild dense clinical tables into reviewable evidence
Use custom design when approved clinical data needs clearer charts, consistent terminology, and a hierarchy clinicians can inspect quickly.
