  1.

  2. Journals’ Statements of Ethical Requirements for Authors • Requirements for publications of clinical trials cover human subjects protection, disclosure of conflicts of interest, and authorship ethics. • Journals publish statements detailing norms. • Authors affirm their compliance with the norms. • The content of these statements are evidence of professional ethical expectations for authors.

  3. Prior Literature on Requirements for Authors • Previous studies focused on human subjects protection. • They used convenience samples and did not explore variation across journals. • In the population of journals publishing RCTs, what are expectations for human subjects protection, conflict of interest, and authorship ethics? • What explains variation across journals in requirements?

  4. Journals Publishing Clinical Trials (CTs) in 2005 We used Haynes et al.’s ‘conservative’ strategy to retrieve CTs from PubMed. We retrieved 13,184 references to CTs, published in 2,056 journals. Average journal published 6.4 articles. Median = 2.5 articles. Top 25% of journals publish 74% of articles.

  5. Journals by CT Count: Log-Log Plot The distribution of journal CT counts falls somewhere between a Power Law (dashed line) and Log-Normal (curved line). 80/20 laws: Web site hits, crime, income, journal citations. Matthew effect: “Unto him that hath, shall be given.”

  6. Sampling Journals & the Distribution of CTs Looking just at high impact / high prestige journals would just give us data on a very select set of journals. So, we sampled all journals that published 50 or more CTs in 2005, and randomly chose journals from the rest. However… simple random sampling of journals would give us very few of the journals that matter to the most readers and that publish a disproportionate share of articles. This meant that journals that published < 50 CTs were undersampled. So we weighted them in the analyses to correct for the undersampling.

  7. Scientific & Ethical Quality Control • We retrieved instructions to authors from the web or sent a request to the journal editor. • We coded the instructions for the following: • Journal Self-Interest: e.g, no previous publication. • Human Subjects: Informed Consent + IRB review. • CT Standards: CONSORT + Registration

  8. Components of Authorship Ethics (AE) Score • Disclosures: Source of funding, COIs. • Authorship: Author Contributions, Components of Authorship as defined by Vancouver. • Affirmations of Responsibility: For scientific work and data integrity. • 10 elements in total, Cronbach’s  = .87.

  9. Journal Requirements N = 289 journals, weighted analysis.

  10. Estimated Population Density: Authorship Ethics Requirements N = 289 journals, weighted analysis.

  11. What Journal Factors Affect Authorship Ethics? • Negative binomial regression predicting number of AE elements present (with weights). • Model includes journal age, CT count, US or European publication, journal ‘discipline’, and whether the journal was electronic. • Important methods problem: Journals are not independent observations.

  12. What Journal Factors Are Associated with AE? Where the journal is published does not matter. Only statistically significant ‘discipline’ factors are shown. Journal age is associated with AE (older have higher AE), but not when you control for CTs Published.

  13. Authorship Ethics Score & Number of CTs Published in 2005 N = 289 journals, weighted analysis.

  14. Conclusions • CTs are published in a ‘long tail’ of journals: Many appear in lesser known journals that previous studies have ignored. • AE requirements vary across journals. • Journals publishing many CTs have stiffer requirements. • AE requirements may vary by discipline; pure electronic journals had high AE requirements.

  15. Implications for Ethics Research on Scientific Journals • Studies of journal population should use epidemiological rather than convenience designs. • Studies should look for journal factors associated with variation in ethical requirements. • Don’t just look at the high volume journals. There is also a ‘long tail’ of small journals • How will E-publishing affect AE policies?
