Only a quarter of endoscopic research is fully published

Only 25% of abstracts reporting endoscopic research that are submitted to the American Society for Gastrointestinal Endoscopy, are published, according to researchers from Durham, North Carolina, USA.

The researchers determined factors associated with the fate of endoscopic research abstracts submitted to the annual scientific meeting of the American Society for Gastrointestinal Endoscopy (ASGE). They reported their findings in March's issue of Gastrointestinal Endoscopy.

All abstracts (n = 461) submitted to the annual meeting of the ASGE in May of 1994 were retrospectively reviewed.

A number of databases were searched for evidence of publication of the abstracts in full-manuscript form. Univariate and multivariate analyses were performed to determine the association between abstract characteristics and acceptance for presentation at the meeting and for publication.

Abstracts more likely to be published:
- Those reporting positive results
- Studies from outside the US
Gastrointestinal Endoscopy

55% (247/451) of submitted abstracts were accepted for presentation.

In both univariate and multivariate analyses, pediatric studies, prospective studies, randomized studies, and studies from university-affiliated medical centers (UAMC), were more likely to be accepted for presentation.

The overall publication rate was 25.1%. This is lower than that in any published report from other medical societies, claim the authors. The publication rates 1, 2, 3, and 4 years after the meeting were 6.7%, 16.2%, 22.8%, and 25.1%, respectively.

Multivariate Cox proportional hazards analysis showed that accepted abstracts reporting positive results, and studies from outside the United States were more likely to be published in manuscript form.

Dr Mohamad A. Eloubeidi, of the Duke University Medical Center, Durham, North Carolina, said, "Although there was no positive outcome bias for acceptance of abstracts for presentation at the meeting, there was bias toward publication of statistically significant results."

"Further investigations are warranted to determine the variation in the publication of research results according to country of origin, and to determine factors that hinder publication of GI endoscopic research in manuscript form," it was concluded.
