High-quality evidence syntheses are essential for guiding evidence-based healthcare and policy decisions. Yet, an increasing number of methodologically flawed reviews—often single-authored, lacking comprehensive searches, dual screening, proper risk of bias assessment, or certainty-of-evidence evaluation—are being published in peer-reviewed journals. Such practices risk misleading decision-makers, undermining public trust, and diluting the scientific value of evidence synthesis. In this webinar, we discussed how the peer review and journal editorial process can play a critical role in safeguarding the integrity of evidence synthesis. Drawing on personal and professional experiences, the presenters outlined practical strategies for strengthening peer review and editorial oversight, including enforcing reporting guidelines, improving editorial and reviewer expertise, and exploring the responsible use of artificial intelligence. The session highlighted how rigorous peer review processes can ensure trustworthy syntheses that inform policy, practice, and public understanding.
