Cochrane has implemented a new system for checking whether any of its thousands of published reviews include retracted studies in their analyses, the organization announced on June 10, 2026. The effort already has turned up dozens of reviews that do and will now get closer scrutiny to ensure their results and recommendations hold up.

Cochrane publishes systematic reviews on health-related topics that evaluate the strength of evidence on particular treatments and interventions. Professional organizations and policymakers use the more than 9,500 reviews when developing recommendations. Recently a study of anesthesia clinical trials found a high rate of the studies with faked or flawed data, and another revealed that retracted studies included in systematic reviews — 17% of which were Cochrane reviews — had a large impact on clinical guidelines derived from them.
