What does an editor look for in a paper? Content
Ideal paper Addresses a novel question Addresses important clinical question that
will be of general interest Answers a controversial question
Real paper “Next steps” Not just confirmatory

What does an editor look for in a paper? Study design
Strong design—RCT, observational cohort, case-control
Design fits the hypothesis Data source provides information on
confounding variables Sufficient power Generalizable or clear about what
population results apply to

What does an editor look for in a paper? Presentation
Indicates what is known and not known about topic and how this study fills gap
Clearly analyze and present data Interpret data appropriately Well written

Editor Reading Papers
![Page 7: Scientific Writing for MCH Epidemiologists Jody W. Zylke, MD Senior Editor JAMA.](https://reader036.fdocuments.us/reader036/viewer/2022062716/56649de75503460f94ae1360/html5/thumbnails/7.jpg)
Fatal Flaws
Usually related to study design Negative underpowered study Predictive model that isn’t validated Survey with inadequate response rate
![Page 8: Scientific Writing for MCH Epidemiologists Jody W. Zylke, MD Senior Editor JAMA.](https://reader036.fdocuments.us/reader036/viewer/2022062716/56649de75503460f94ae1360/html5/thumbnails/8.jpg)
One strike you may be out
Topic of article doesn’t suit journal Case report, animal study, specialized
Failure to provide enough information on methods to judge validity
Failure to address sources of bias and study limitations
Conflicts of interest Sloppiness Failure to follow journal format, instructions
![Page 9: Scientific Writing for MCH Epidemiologists Jody W. Zylke, MD Senior Editor JAMA.](https://reader036.fdocuments.us/reader036/viewer/2022062716/56649de75503460f94ae1360/html5/thumbnails/9.jpg)

What an Editor Wants in a Paper

“Writing is easy. All you have to do is sit and stare at the blank sheet of paper until the drops of blood form on your forehead.”
---Gene Fowler

Tips for Scientific Writing
Just the Facts Follow the formula Three qualities of scientific prose
(Huth) Accuracy Clarity Brevity
![Page 13: Scientific Writing for MCH Epidemiologists Jody W. Zylke, MD Senior Editor JAMA.](https://reader036.fdocuments.us/reader036/viewer/2022062716/56649de75503460f94ae1360/html5/thumbnails/13.jpg)
Accuracy
Spelling errors Defective choice of verb tense
Past tense in describing your results; present tense describing literature
Commonly misused words Incidence vs prevalence That vs which Effect vs affect Case vs patient
![Page 14: Scientific Writing for MCH Epidemiologists Jody W. Zylke, MD Senior Editor JAMA.](https://reader036.fdocuments.us/reader036/viewer/2022062716/56649de75503460f94ae1360/html5/thumbnails/14.jpg)
Clarity
Ambiguous antecedents (“He is a person with many convictions.”)
Poor choice of verb tense
Modifiers (“Hospital nurse physician staff interaction”)
![Page 15: Scientific Writing for MCH Epidemiologists Jody W. Zylke, MD Senior Editor JAMA.](https://reader036.fdocuments.us/reader036/viewer/2022062716/56649de75503460f94ae1360/html5/thumbnails/15.jpg)
Brevity
“After careful consideration of all the foregoing lines of evidence, it is apparent to us that among all the antibiotics discussed penicillin is the one that should be chosen for the treatment of infections caused by the streptococcus.”
“We conclude that penicillin is the best antibiotic for treatment of streptococcal infections.”
“Streptococcal infections? Penicillin!”
![Page 16: Scientific Writing for MCH Epidemiologists Jody W. Zylke, MD Senior Editor JAMA.](https://reader036.fdocuments.us/reader036/viewer/2022062716/56649de75503460f94ae1360/html5/thumbnails/16.jpg)

“Because”) Despite the fact that (Use “Despite”) Fewer in number (Use “Fewer”) In order to (Use “To”) It is often the case that (Use “Often”) Very, Extremely (Delete)

Grace
Dehumanizing words A diabetic vs a woman with diabetes Male and female
Pomposity “It is an inescapable conclusion that utilization of
this method in order to make the diagnosis . . .” Try “I conclude that use of this method . . .”
Slang, jargon, cliches prepped, lab, flat line, exam, status post
![Page 19: Scientific Writing for MCH Epidemiologists Jody W. Zylke, MD Senior Editor JAMA.](https://reader036.fdocuments.us/reader036/viewer/2022062716/56649de75503460f94ae1360/html5/thumbnails/19.jpg)
Other Prose Features
Vary Sentence Structure and Length “It is easy to craft a story about the FDA based on just a
couple of actions, out of hundreds taken each year. So competing narratives abound. Some claim the FDA is captive to manufacturers and too quick to approve new therapies; others assert the agency is safety obsessed and too slow to make treatments available.” –Joshua Sharfstein
Logical flow of paragraphs, Avoid passive voice (active verbs instead of forms
of “to be”) Use key terms consistently
![Page 20: Scientific Writing for MCH Epidemiologists Jody W. Zylke, MD Senior Editor JAMA.](https://reader036.fdocuments.us/reader036/viewer/2022062716/56649de75503460f94ae1360/html5/thumbnails/20.jpg)
