Abstract

BACKGROUND:

A survey of journals published in the field of Gastroenterology conducted 5 years ago showed marked variability in reporting of conflicts of interest or funding sources in these journals.

AIM:

To re-examine reporting of conflicts of interest and funding sources for original articles and editorials in Gastroenterology and Hepatology journals.

METHODS:

We evaluated all original articles and editorials in 15 leading journals (determined by impact factor-Thomson Reuter Science Citation Index) devoted to Gastroenterology and Hepatology for disclosures of conflicts and for editor's self disclosures. We examined each journal's editorial policy by contacting the journal directly if the information was not revealed on the Web site or print versions of the journal.

RESULTS:

Of the 1574 articles evaluated, a total of 1207 (77%) reported the presence or absence of a potential conflict of interest and 1047 (67%) reported the presence or absence of funding sources. A total of 3 of the 15 (20%) journals (American Journal of Gastroenterology, Gastroenterology, and Alimentary Pharmacology and Therapeutics reported the presence or absence of funding sources in all their published original articles. Only 5 of 15 (33%) journals (Gut, Gastrointestinal Endoscopy, American Journal of Gastroenterology, Neurogastroenterology & Motility and Alimentary Pharmacology and Therapeutics) publicly disclosed the conflicts of interest of the editors.

CONCLUSIONS:

(i) Funding sources and conflicts of interest are still reported variably in the GI literature. (ii) Editorials and review articles are influential, but have poor reporting of conflicts of interest. (iii) Editors of many journals still do not report their conflicts of interest.
