Researchers found that retraction notices in PubMed take about 35 months to stabilize after publication. This delay impacts studies analyzing retractions, affecting fraud and error investigations.
Area of Science:
- Bibliometrics
- Scientific publishing
- Scholarly communication
Background:
- Scientific integrity is crucial, with retractions addressing fraud and errors.
- Retraction notices are indexed in databases like PubMed.
- Previous studies analyzed retraction notice cohorts.
Purpose of the Study:
- To evaluate the stability of PubMed's retraction notice indexation.
- To determine the time lag for retraction notice data to stabilize.
Main Methods:
- A PubMed search for "retraction of publication" notices from 2008 was conducted repeatedly over 15 months starting February 2011.
- The stability of the search results was monitored for discrepancies.
Main Results:
- The initial search yielded 237 retraction notices.
- Over the study period, 14 discrepancies (6%) were noted.
- Retraction notice counts stabilized approximately 35 months after the retraction date.
Conclusions:
- A significant time lag exists for retraction notices to stabilize in PubMed.
- Researchers must account for this lag in PubMed searches for retraction analysis.
