Scope and Impact of Financial Conflicts of Interest in Biomedical Research: A Systematic Review

Bekelman, Justin E., Li, Yan, Gross, Cary P.·2003·JAMA

Abstract

CONTEXT: Despite increasing awareness about the potential impact of financial conflicts of interest on biomedical research, no comprehensive synthesis of the body of evidence relating to financial conflicts of interest has been performed. OBJECTIVE: To review original, quantitative studies on the extent, impact, and management of financial conflicts of interest in biomedical research. DATA SOURCES: Studies were identified by searching MEDLINE (January 1980-October 2002), the Web of Science citation database, references of articles, letters, commentaries, editorials, and books and by contacting experts. STUDY SELECTION: All English-language studies containing original, quantitative data on financial relationships among industry, scientific investigators, and academic institutions were included. A total of 1664 citations were screened, 144 potentially eligible full articles were retrieved, and 37 studies met our inclusion criteria. DATA EXTRACTION: One investigator (J.E.B.) extracted data from each of the 37 studies. The main outcomes were the prevalence of specific types of industry relationships, the relation between industry sponsorship and study outcome or investigator behavior, and the process for disclosure, review, and management of financial conflicts of interest. DATA SYNTHESIS: Approximately one fourth of investigators have industry affiliations, and roughly two thirds of academic institutions hold equity in start-ups that sponsor research performed at the same institutions. Eight articles, which together evaluated 1140 original studies, assessed the relation between industry sponsorship and outcome in original research. Aggregating the results of these articles showed a statistically significant association between industry sponsorship and pro-industry conclusions (pooled Mantel-Haenszel odds ratio, 3.60; 95% confidence interval, 2.63-4.91). Industry sponsorship was also associated with restrictions on publication and data sharing. The approach to managing financial conflicts varied substantially across academic institutions and peer-reviewed journals. CONCLUSIONS: Financial relationships among industry, scientific investigators, and academic institutions are widespread. Conflicts of interest arising from these ties can influence biomedical research in important ways.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Several investigations show strong associations between the source of funding and the conclusions of research articles.

    “Several investigations show strong associations between the source of funding and the conclusions of research articles [ 219 – 222 ].”
  • These factors can affect RCTs from conception to the reporting of results and conclusions.

    “These factors can affect RCTs from conception to the reporting of results and conclusions [13, 32, 33].”
  • Transparent and reproducible science offers well-established benefits: enhanced research reliability and credibility, increased applicability of results, and reduced bias and waste of resources.

    “Transparent and reproducible science offers well-established benefits: enhanced research reliability and credibility, increased applicability of results, and reduced bias and waste of resources [10–14].”
  • Reporting funding and conflicts of interest helps prevent bias; reinforces researchers' commitment to conducting research impartially; and enables readers, reviewers, and editors to better assess results by understanding potential external influences.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
