Positive-outcome bias and other limitations in the Outcome of research abstracts submitted to a scientific meeting.
International Congress on Peer Review in Biomedical Publication. Prague, CZE, 1997/09.
Studies with positive results are more likely to be published in biomedical journals than are studies with negative results.
However, many studies submitted for consideration at scientific meetings are never published in full ; bias in this setting is poorly studied.
To identify features associated with the fate of research abstracts submitted to a scientific meeting.
Design and Setting
- Prospective observational cohort, with 5-year follow-up of all research submitted for consideration to the major annual 1991 US research meeting in the specialty of emergency medicine.
- All research abstracts submitted for consideration at the meeting for possible presentation.
Main Outcome Measures
- Characteristics associated with acceptance for presentation at the meeting and subsequent publication as a full manuscript.
- A total of 492 research abstracts were submitted from programs in emergency medicine and other specialies affiliated with 103 US medical schools.
A total of 179 (36%) were accepted for presentation and 214 (43%) were published in 44 joumals.
Of the 179 abstracts accepted for presentation, 111 studies were published.
Scientific quality of abstracts or prestige of the journal in which the study was eventually published did not predict either of these outcomes.
The best predictors (by logistic regression) of meeting acceptance were a subjective « originality » factor (odds ratio [OR], 2.07 ; 95% confidence interval [Cl], 1. (...)
