Effective poster and oral presentations AJ Frew University of Southampton, UK
Purpose of poster • To show work and excite comment • To generate advice for future work • To obtain feedback for writing up • To make a mark and solicit collaboration
Horses for courses • Different layout and content needed for • Fully attended poster • Poster discussion symposium • Unsupported poster • Consider providing paper copies • Have the organisers arranged for electronic/CD collection of posters?
Key components • Abstract • Title • Context/ Introduction • Figures • Summary • Discussion points
Abstract • Advertisement of work • Basis of selection for display • Attracts viewers • May be citable and attract interest after meeting
Title • Also attracts viewers • Must be legible from distance • Clear message
Context/Introduction • Explains why study was done • Limited amount of background • Include hypothesis being tested • Avoid excessive amounts of text
Methods • Use photographs where possible • Essential detail only (unless purpose of poster is to show a new method) • Use large font • Use space
Local Allergen Challenge 10 minutes baseline
Results • Just key results • Figures preferable to tables • Supply full legends • Logical sequence of experiments/data • Consider summary with linking lines • Logical layout, using board space to best effect

Summary • Cogent summary • Fair & accurate conclusions • Discussion points • to excite comments and interest • to help with further experiments • to help with writing up paper
Role of presenter • To engage with passers-by • To answer queries • To receive feedback • Aim is to use time for discussion, not to explain methods repeatedly!
What makes a good poster? • Clarity of purpose • Appropriate use of figures and legends • Small amount of legible text • Enthusiastic presenter
Purpose of oral presentation • To show work and obtain feedback for writing up • To make a mark • OPs are less useful than posters for: • getting comments and feedback • getting advice for future work • getting future collaborations • Few questions, and usually simple ones
Before starting • How long have I got? • How much time is allocated for discussion? • Who is the audience? • What are the main results/points? • (one sentence summary)
How many slides? • Aim for one slide per minute • More is possible but may appear rushed • Two per minute will always be too many • Audience need time to orient themselves • You will usually remember some extra things that you want to say • Allow time for changeover and thanks to organisers etc
Key components of an oral presentation • Context/ Introduction • Method • Results • Summary • Discussion points
Context/Introduction • One slide to explain why study was done • Include hypothesis being tested • Avoid excessive amounts of text • Avoid long explanation of “iconic” cartoon • Consider highlighting the area of interest

Methods • How much do you really need to show? • Use photographs if appropriate • Essential detail only • (unless primary purpose of presentation is to show a new method)
Methods • Diesel exhaust was generated from an idling Volvo engine (built 1993), diluted with filtered ambient air and pumped into an exposure chamber in the next room. • On control days the engine was left running but only filtered air was supplied to the chamber • Particulate and gas concentrations were measured on a continuous basis
Diesel exposure chamber (National Inst of Working Life, Umeå)
Results • Identify key results and stick to them • Avoid data tables • Avoid figures from papers • Prepare figures to show key points
Results -common faults • This is a very busy slide, but if you look over here in the corner you can see….. • As you can clearly see….. • I’m sorry. I made this slide for another meeting, but if you ignore this part of the graph…… • Some of you at the back may not be able to read this
Laser Pointers/Highlights • Use laser pointer sparingly • Support your wrist • Don’t “hosepipe” • Consider using powerpoint features to draw audience to your key points: e.g. • ring highlights • building up graphs

For complex built-up figures, make whole figure, then make copies and delete parts
Summary • Bullet points only • Discussion points • to acknowledge weaknesses • to compare with previous knowledge • to excite comments and interest • to help with writing up paper
Acknowledgements • Can take a long time • Often excessive • Often uses up a large proportion of discussion time • especially if your presentation or the whole session is running late • Consider giving acknowledgements at beginning (as part of title slide)
Oral presentation • Plan to use your time wisely • Leave time for discussion • Prepare clear figures to show results • Use powerpoint features, • but don’t overdo it • Speak slowly - “Less is more” • Give audience some ideas for discussion • Rehearse with an honest friend
