How to write and
An interactive, extensive, one-day workshop
1. Structure of the research paper
2. Golden Rules of scientific writing
3. Common Errors in scientific writing with examples
4. Tips to make a world-class research paper
5. How to write a conference abstract
6. How to select a suitable journal
7. Flow of the publication process
8. How to address reviewers' comments
1. Structure of research paper
Manuscript text (IMRaD)
• Case report
• Case Series
• Literature Review
• View Point
• Letter to Editor
• What we know
• What we do not know
(Gap of Knowledge)
• Aim of this work
1. Study design (How?)
7. Sample size
8. Intervention/Condition being observed
9. Outcome measurement
10. Data collection
11. Data entry
12. Statistical analysis
• Interpretation of results
• Are results statistically significant?
• Are results clinically significant?
• Give possible justifications
(why drug X was better than drug Y?)
• What did previous studies
concluded about this topic?
• Is your study in accordance with
• If not, justify this contradiction
• Study strength points
• Study limitations
• Implications for clinical practice
• Implications for future researchers
• Final conclusion
• Put actions in verbs
• Put characters in subjects
• Keep subjects near verbs
• Put new information last
• Use active voice
• Make sure the first and last sentences of a paragraph match
• Omit needless words
• Prefer simple words
• Use simple subjects
• Use short sentences
• When starting the sentence, don't overdo using “But” or “And”. “But” has become
quite acceptable; 'And' less so.
• Always try to put the words that relate to one another as close together as possible.
• Use common, everyday words rather than obscure or complex words.
Rules for reporting numbers
• Numbers less than 10 are words.
• Number 10 or more are numbers.
• Words not numbers begin a sentence.
• Be consistent in lists of numbers.
• Numbers less than 1 begins with a zero.
• Do not use a space between numbers and its percent sign.
• Use one space between a number and its unit.
• Report percentages to only one decimal place if the sample size is larger than 100.
• Do not use decimal places if the sample size is less than 100.
• Do not use percentage if the sample size is less than 20.
• Do not imply greater precision than your measurement instrument.
• For ranges use "to" or a comma but not "-" to avoid confusion with the minus sign and
use the same number of decimal places as the summary statistic.
• Rules for data numbers do not apply to citations to the literature.
The decision to begin the treatment regimen requires certain prerequisites, one of the most
important is the determination of liver fibrosis stage by pathological examination of a liver
tissue sample which remain the gold standard to evaluate the stage of liver fibrosis (3,4).
Determining the stage of live fibrosis is a prerequisite to start the treatment regimen. Till
the moment, pathological examination of a liver tissue is the gold standard method to
determine the stage of fibrosis.

Follow the Standard Reporting Guidelines
Standard guidelines for reporting research studies have been
developed and undergo acronyms such as CONSORT, MOOSE,
QUOROM, STRAD, STROBE and PRISMA. Highly ranking
journals in addition to the International Committee of Medical
Journal Editors (ICMJEs) recommends standard reporting of
research studies according to these guidelines.
When you start writing
ABSTRACT = الملـخص
Indexing in databases
Subscription Journals (non-OA)
For readers: Get quick overview
Why is abstract
• Identify the main issue of your paper
• Begin with the subject of your paper
• Accurate, unambiguous, specific, and complete
• Do not contain abbreviations
• Attract readers
Criteria of a good title
Sentence no 3
Aim of this study
Sentence no 2
A more specific sentence about the Factor/Agent
Sentence no 1
About the General Topic/Disease/Condition
The methods section of the abstract should describe the study
design, who was studied, what you measured, and how you
analyzed the data. If it matters, you should mention where the
subjects came from and how they were selected. Specify the
number of subjects, by group if appropriate. All important
measurement techniques should be described.
You can leave out obvious methods (‘‘Subjects were asked their
age and sex’’), as well as intricate details, unless they absolutely
• Make sure you emphasize the main finding of the study.
• Concentrate on various aspects of that single result, such as the
effects of adjusting for potential confounders, of using
alternative definitions, or of looking for dose-response effects.
• It is better to be profound/deep than broad-based.
• Do not just present P values, F statistics, or regression
coefficients. Make sure your effect size is clear.
• State your key results in words, followed by the numbers.
For example, suppose you find that hypertensive patients who take calcium
channel blockers are more likely to have strokes. It is more important to present
your results by type of calcium channel blocker (long-acting vs. short-acting) and by
type of stroke (ischemic vs. hemorrhagic), and to show that patients taking other
antihypertensive medications did not have an increased risk, than to present
extraneous data with small P values such as the finding that ‘‘patients who took
diuretic medications had more gallstones (P<0.01).’’
‘‘Patients treated with Gentamycin were nearly twice as likely to require dialysis as
those treated with other aminoglycosides (20% vs. 11%; RR=1.9; 95% CI=1.3 – 2.8).’’
• Do not repeat the results in slightly different words, or make
superfluous declarations such as ‘‘These results may have clinical
importance,’’ ‘‘Our results should be confirmed by other investigators,’’ ‘‘Our
findings support our hypothesis,’’ or ‘‘Further research is needed.’’
• Make a reasonable statement about the implications of your results.
• If the results have, or may have, clinical meaning, then say how.
• If another study is needed, then state what sort of study it should be.
Why Abstracts are rejected
1.Dull topic (not interesting or a lot of previous research)
2.Small Sample Size
3.All numbers, No talk
4.All talk, No numbers
6.Too many abbreviations and too much data
7.Sentences that invite rejection
8.Many P values; Less focus on effect sizes
9.Overuse of Respectively
Sentences that invite rejection
There are two phrases that will almost always result
in your abstract being rejected: ‘‘Data will be
presented’’ and ‘‘Results will be discussed.’’
Never include either of these phrases in an abstract
unless you have been invited to make a presentation
at the meeting and were asked to submit an abstract
for the audience’s benefit.
What is different colleagues want to
present the same abstract?
Dishonest behavior …
