Where are the title
and the abstract?
Title and Abstract
The are the “business card“of the whole paper…
What you will learn• Writing the Title and the Abstract
– goals of Title– goals of Abstract– effective tips
Title
What makes a good title?
First you need to ask yourself what a title is for!
Title
The title is like the eyes of a woman
Title
The title is like the eyes of a woman
They may mislead, but they are decisive in making the choice for having a glance at the article
Title A good title should:
1. Accurately, completely, and specifically identify the main topic
2. Be unambiguous
3. Be concise
4. Begin with an important word to attract intended readers
5. Include independent and dependent variables and species, if not human
6. Be a label suitable for indexing
Title Avoid:
– Too scholarly or too “cute” titles– Acronyms– Roman numerals– Abbreviations– Noun clusters
• Complement fixation laboratory techniquefor adult rhesus monkey antigen isolation
– Questions (sometimes they can be used in a “provocative” way)
Don’t use “jargon” or “phrases”
Keep word order simple
Mauri et al, Circulation 2005
Agostoni et al, AJC 2006
Title “Provocative” questions
Versus
Valgimigli et al, JAMA 2008
Title Subtitles
Try to minimize them
Fajadet et al, Circulation 2006
Title
• Write it first, as soon you develop your hypothesis
• Try to state the “idea” behind the study in the title
• Be specific but catchy
• On the other end, do not make it too specific, or
people might not read or cite it
Title • Optimally:
–Very brief summary of research
•Omits “A study of,” “Investigations of,”…
•Put subjects studied (eg octuagenarians)
•Put limiting information
•Avoid “cute” or abbreviations
–May or may not give results
•Topic – Effects of distal protection on the risk of
periprocedural stroke during carotid stenting
•Conclusive – Distal protection reduces periprocedural
stroke during carotid stenting
Title • Topic
• Conclusive

A DETAILED ANGIOGRAPHIC ANALYSIS
Agostoni et al, AJC 2007
Title
CONSORT for RCT
STARD for diagnostic studies
QUOROM and MOOSE for meta-analysesReport in the title the word “systematic review” or “meta-analysis”

• A Randomized Comparison of Zotarolimus-Eluting Versus Paclitaxel-Eluting Coronary Stents
• Improved Event-Free Survival After Drug-Eluting Stenting in Patients with Unprotected Left Main Disease
• Long-Term Clopidogrel Administration Prevents Late Drug-Eluting Stent Thrombosis
• Abnormal TIMI Frame Count as a Predictor of Unfavorable Remodeling After Primary Angioplasty

Abstract
What makes a good abstract?
First you need to ask yourself what an abstract is for!
Abstract
The abstract is like
the whole body
of a woman
It may mislead, but it is decisive in making the
choice for reading the full-text of the article
Abstract
A good abstract should:
1. State the principal objectives and scope
of the investigation
2. Describe the methods employed
3. Summarize the results
4. State the principal conclusions
Abstract
1. It's by far the most important part of the paper (because most people only read this…)
2. Write it before the rest of the paper, not after
3. Rewrite it after you finished the rest of the paper
4. Start with a rationale for the study: state why you
did it, not what you did
5. Include as much detail of methods as possible
6. Include magnitudes of effects in the results
Abstract
7. End with the main conclusion: state why or how
it's useful, not a rehash of what you found
8. It should be within a few words of the prescribed
length (usually between 200 and 300)
9. Be as economical with words as possible, but do
not compromise grammar
10. Minimize abbreviations here
11. Do not include references, figures, or tables

Results 3-5 phrases
(And)
Conclusions 1-3 phrases
Abstract • Abstracts are short but time-consuming
• Very information-dense, but simply formatted
• Write “long” and pare down if needed
• Analyze one sentence at a time
– Each sentence has purpose
– Each sentence logically follows another
• Use plain English wherever you can
• Use active voice when you can
• State only your most important conclusion(s)
• There is not good writing, only good rewriting
Abstract - Introduction
• What is the general topic you were
investigating and why is it important?
• Provide supporting information for title
• Generally max 3 sentences
• General information to specific
Abstract - Aim
• What are the specific questions you
are addressing with this project?
• Sometimes you need two
sentences, but one is better
Abstract - Methods
• How did you do this experiment?
• One or two sentences are needed for
short abstracts (200 words). Three or
four for longer (300 words).
• Just to give general idea
• No statistical analysis
• No vendor info needed
Abstract - Results
• What did you find out?
• Two sentences might be enough: state only
you main point(s).
• Include your most important data that
influenced your conclusion:– mean values, standard deviations, p values, confidence
intervals, number of samples you studied, etc.
Abstract - Conclusions
• Sometimes called Discussion or
Interpretation
• How did hypothesis turn out?
• What is the big point that you want to
take home?
• One sentence may be enough
• Be bold, yet not overconfident
Abstract The more structured, the better

Tips
Title drafting
-keep focused and precise but catchy!
Abstract drafting
-every phrase is a battle, and the whole abstract is your war, win or loose!
-follow the IMRAD approach
-never tell lies, better (slightly) conceal the truth
