Abstracts for Scientific Meetings
• Important for transmitting new information,
“cutting edge”
• Important for career development
• Important to become known in the field
• Important for you to get to know others in the
field, enhance networking opportunities
Abstract Basics
• One abstract per research question
• No duplicate abstracts at different meetings
• Goal: 1 manuscript per abstract
Why are abstracts rejected
•
•
•
•
•
•
•
Dull topic, nothing new
No context provided
Small number of subjects
All talk, no data (“results will be discussed…”
All data, no talk
Poor readability
Sloppy
Abstract Format
• Read the instructions
• Format the “box” or other limitations
• Include:
– Introduction/background/purpose
– Methods
– Results
– Conclusions
Abstract format
• Introduction
– 1-2 sentences
– Include the research question (hypothesis) or
purpose at the end
– Avoid jargon, excessive abbreviations
– Assume reviewer(s) are not the most
knowledgeable in the field
Abstract format
• Methods
– Include study design
– Study population (#, age, M,F, inclusion criteria)
– What was measured
– How data was analyzed (if space), otherwise
include during the talk/presentation
Abstract format
• Results
– Main finding of the study – in words
– Give real numbers as well as significance
– Tables can be helpful
Abstract format
• Conclusions
– What do your findings mean
– Do not repeat results
– If you could have written your conclusion before
you knew your results – you don’t really have a
conclusion
Abstract Presentations - oral
• “The 10 minute talk”
– Garson, et al, Am Heart J 1986; 111: 193-203
• Write out every word: better to read than to
stumble or go over time
• Usual rule: 1 minute per slide (maximum 30
sec per slide for non-complex statements)
• Absolute maximum = 14 slides per 10 min.
Abstract presentation
• Preparing slides
• 20 point minimum (this is 32 point)
• This is 20 point

Abstract presentations

Use horizontal format
Center all material
No more than 7 lines per slides
No more than 7 words per line
How to increase data per slide
without reducing readability
• Use title/heading area or draw a line under
title
• Use bullets, especially if the statement uses
more than one line
• Underline the points
• Use color
Slide tricks
1. Number the points
2. Use underlining above subheadings
Slide tricks
• Purpose
– Devise a new technique to keep your audience
awake
– Increase odds of publishing
Slide tricks
• Use color
– Methods
• 300 patients with CHF
• Admitted for syncope
• 100 M; 200 F
• All underwent Holter monitoring, EP testing, tilt
table
Inexcusable!!!
• “I know you probably can’t make out what’s
on this slide, but…”
• “I apologize for the complexity of this slide,…”
• “Ignore the details on this slide, I just want to
focus on …”
Slide construction
• Title for every slide
• Use phrases but should be readable
• Common abbreviations ok if appropriate
– Pts, M, F, CHF, LV, MI
– Be careful of language differences
– Try to avoid ** and footnotes (distracting)
Slide construction
• Tables
– Use if the numbers are important, rather than the
relationship
– Avoid more than 4 rows (for 2 columns)
– If 3 columns, use 3 or less rows
– For a “p” value column, list “NS” for p>.05
– For others use 0 before . “p<0.01”

treatment to different groups
• Use less than 6 bars
• (no more than 8 maximum)

The Title
• Ideally: it should encourage the reader to be
interested enough to want to see more
• It should not lead to any of the following
reactions
– “not again!”
– “I don’t believe this”
– “How boring”
– “Huh?”
Title
Should say a lot about your research
When in doubt: choose a declarative statement
Ask colleagues and coauthors (should have a
consensus)
The key features should be in the title
(clinical trial, children with ear infections, new
antibiotic)
Title – Giving the results?
• “Antibiotic X improves survival in neutropenic
sepsis”
• Those who say no:
– Interpreted as bragging?
– Will get lower marks if not the final trial results
(e.g. preliminary findings)
Titles – stating results
• May highlight what’s new about your study,
especially if the population or intervention
have been studied before
• Can interest the reader
• And the reviewer
• Key point is to be objective – don’t overstate
Other considerations
• Pros and cons of stating the results: “B52 genotype
reduces survival in Disease X”
– Will clearly give the reader the content of your
study
– But, may be “too assertive”
• Can seem like bragging
• What if it conflicts with previous work, e.g. the
reviewers?
• More objective (i.e. safer): “Effect of B52 genotype
on Survival in Disease X”
Highlight particular strengths or new
methodology
• Especially if this is one of many studies on the same
topic
– “Association of protein Z with low cholesterol
levels and dementia”
• Specify study population (e.g. rodents or humans)
when submitting to a journal/meeting where either
might be presented
– “Risk of renal failure in trauma patients with
hematuria”
Title Checklist
• Are the title and research question closely
related?
• Is the title objective in tone?
• Are special features of the study mentioned –
especially the study population (elderly,
women, racial/ethnic group)
Examples
• What not to do (from the world of journalism)
At least we know it’s effective!
Giving the talk
• Have your 1st slide up
– Usually, title of talk, authors, affiliation
• Begin thanking the moderators (learn their
names)
• “Thank you Dr. Jones. Dr. Miller, ladies and
gentlemen,…”
• Or, “Dr. Jones, Dr. Miller, ladies and
gentlemen….”
Giving the Talk
• Be sure you use the same words in your talk as
are on your slide
Example
• Slide: All sudden death outside hospital
• Say, “All sudden deaths occurred outside the
hospital.”
• Do not say, “All patients who died suddenly
did so outside the medical center.”
Slide transitions
• Pause slightly
• You have control
• Indicate in your written text when you will transition
– symbol, e.g.
• For graphs, first orient the audience
– “This slide shows the occurrence of cardiac events
over time. The horizontal or X axis displays time in
years and the vertical axis shows the incidence of
cardiac events in percent.”
Abstract presentations
• If you have more data in your presentation
than you showed in the abstract, make a brief
mention, then go on.
– “As you can see, the numbers on this slide are
larger than those reported in the abstract as we
included 50 additional cases.”
Talking about graphic results
• Describe the overall findings after orientating the
audience.
– “We found that heart attacks increased for every
quintile of BMI.”
• Point to only the key features
– “More men than women developed cancer”
– “Women had significantly more embolic events
than men.”
Giving the talk
• Talk about everything on the slide
• If there’s too much, eliminate it from the slide
– You’ll have more room in the manuscript
• For conclusions:
– Use complete sentences
– Read words as in the slides. Some additional transition is
allowed.
– Orient the audience, by “First,…” “Our second
conclusion…” “Finally, …”
At the end
• After your last conclusion recommendation, at
the end of the last slide,
– stop,
– look up,
– say “Thank you.”
• Wait for the moderator to take over.
Questions and answers
• If no microphone, repeat the questions
• Have a pen to jot notes as long-winded questions get
asked
• Be calm
• Be professional
• Do not disagree, if possible
• Be brief
• Be appreciative, thank person if someone makes a
good point.
• OK to say, “We haven’t analyzed that yet.”
Giving the talk
• Practice
• Time yourself
• Give before an audience
• Speak slowly
Precautions
• Bring back-ups
– Flash drive, email to yourself
– Be sure someone else has the slides
• Day of the talk
– Be sure your slides are loaded
– Check in the room of the talk to be sure
everything is ready
Pointer etiquette
• Do not point at every word
• Do not “circle” or “wave” or “squiggle” with
your pointer
• Only point at key aspects of a graph or picture.
If you are clear (in your slides and your talk)
you won’t really need the pointer. Audience
will follow with you.
