In January 2022, we launched a living overview of registered trials assessing non-pharmaceutical interventions (NPIs) to prevent COVID-19. The overview presents key trial characteristics and, once available, links to published results.

  • View the protocol with methodological details on OSF

A scoping review on trials assessing NPIs as of August 2021 identified 41 trials and was recently published in BMJ Evidence-Based Medicine. Additionally, a blog entry has been published in BMJ EBM Spotlight.

Users of COVID-evidence are also able to search the database for NPI trials assessing the topic filter “Preventive non-pharmaceutical interventions (NPI)“.
