I recently added this edit and it was deleted with the comment that it was too general to include:
A 2011 study done to disclose possible conflicts of interests in underlying research studies used for medical meta-analyses reviewed 29 meta-analyses and found that conflicts of interests in the studies underlying the meta-analyses were rarely disclosed. The 29 meta-analyses included 11 from general medicine journals; 15 from specialty medicine journals, and 3 from the Cochrane Database of Systematic Reviews. The 29 meta-analyses reviewed an aggregate of 509 randomized controlled trials (RCTs). Of these, 318 RCTs reported funding sources with 219 (69%) industry funded. 132 of the 509 RCTs reported author conflict of interest [COI] disclosures, with 91 studies (69%) disclosing industry financial ties with one or more authors. The information was, however, seldom reflected in the meta-analyses. Only two (7%) reported RCT funding sources and none reported RCT author-industry ties. The authors concluded “without acknowledgment of COI due to industry funding or author industry financial ties from RCTs included in meta-analyses, readers’ understanding and appraisal of the evidence from the meta-analysis may be compromised.” Noting that most assessment tools for meta-analysis do not include a domain for study funding source the authors state: “Currently, The Cochrane Collaboration’s Risk of Bias tool includes an optional 'other sources of bias' domain, which meta-analysts could use to include information on COIs. We recommend that The Cochrane Collaboration consider formalizing the requirement to assess potential bias from COIs.”
I'd like some feedback. Do editors feel it is appropriate? Perhaps appropriate if only mentioned in the article rather than such a long edit? Thanks! Gandydancer (talk) 14:22, 19 August 2011 (UTC)
I deleted it, because this concerns a much wider issue and is not really a criticism specifically of the Cochrane Library, I feel. --Crusio (talk) 15:12, 19 August 2011 (UTC)
I agree that it is a wider issue, however considering that the Cochrane reviews are mentioned and even singled out in the author's recommendation, it seems to me to be appropriate. I know that when we edit medical articles here in Wikipedia, they are given priority. I sure had no idea that they do not include and take into consideration this information. I do know that when I look at individual studies I always check to see who funded them and industry ties, if any, to the authors. Gandydancer (talk) 15:29, 19 August 2011 (UTC)
