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

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

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

Introduction (± Aim) 2-3 phrases

Methods 2-3 phrases

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
