Evaluating a CV - Paper Emphasis
number of papers rate of publication quality of journals length of papers position in list of authors focus
Publish or Perish!
TUMS workshops on scientific writing
Level 1: Basics Level 2: Focus on international publications Level 3: Practice in writing

Introduction Methods Results Discussion
Introduction: Methods: Results: Discussion: W hy did you start?
W hat did you do?
W hat did you find?
W hat does it all mean?
Write like my friend who sits with me in the canteen and tells me this story.
“When I was an intern in obstetrics I saw several cats in the department. Everyone called them fat cats, but I thought the cats were not fat. So I weighed the cats, and I found that the cats were not fat. Visual impressions can be wrong, you know.”

Introduction
The prevalence of obesity in feline creatures remains as yet an unanswered query.[1-4] There are innumerable reports in medical literature which have addressed this issue,[4-6] albeit with contrasting methodology.[7] In our experience, reports of feline obesity in the Asian literature are conspicuous by their absence. The presence of an appropriate number of felines in the Department of Obstetrics and Gynaecology, prompted the authors to estimate the magnitude of the problem in Asian cats. An ongoing prevailing notion was the untested belief that there was a high prevalence of obesity in cats in Asia. Informed consent...

Title Authors and Affiliation Abstract Introduction Methods Results Discussion Acknowledgments (optional) References
How to write a paper
Most papers are not that exceptional Good writing makes significant difference Better to say little clearly, than saying too much unclearly
Types of Medical articles
Editorial Original Article Review Article Short Communication (short papers) Case Reports Letter to Editor Personal Views
Short communication
Increasingly common Concise introduction Present data and discuss it shortly Only a few tables or figures Number of words limitations
Is your paper a paper, a brief or a research letter?
Easier to get letters & briefs accepted (space). They are indexed!
Decide whether you should submit it as a brief or letter
Case Reports
Medical history of a single patient in a story form.
Lots of information given which may not be seen in a trial or a survey.
Often written and published fast compared to studies e.g. Thalidomide

Politics first!
Authorship
Decide on authors, and their order, as early as possible Preferably before starting the project Authors should only include those who made substantive
intellectual
contribution to the project reported, and can defend the data and conclusions publicly.
Target your paper at a particular journal
Familiarise yourself thoroughly with potential journals what sort of papers do they publish? (original articles, briefs, reviews, commentaries, iconoclastic pieces?) What is the “culture” of the journal?
National or international focus?
Write for that journal

Rejection rate: 15% (pay journals) to 60% (specialist journals) to 90% (NEJM, The Lancet) How long does it take? (Choice of journal) BMJ: 70 days JAMA: 117 days Iranian journals?
RULES OF THUMBS
bad research is almost always rejected
sensational research usually accepted even if badly written
BUT most papers are neither: in gray zone
Questions journals ask Is the research question important?
Is it interesting to our readers?
Is it valid? A scientifically sound study.
What editors look for Short, clear, precise title Good abstract Good design and methods Clear conclusions Brevity Follow instructions
What reviewers look for Good design and methods Simple tables and figures Logical organisation Brevity Balance Appropriate statistics Their papers
