Hot off the press from the #MAGICevidence team.

New study on how guidelines translate into real-world use, focusing on BMJ Rapid Recs

Key message: Methodological rigor builds credibility, but complexity can undermine usability and confidence

Implementability needs to be designed, not assumed.

They founded MAGIC over ten years ago to improve how evidence is generated, translated, and used in clinical decisions. The goal was clear: more transparency, more trust, better patient care. Inspiring to see what it has become.

Are #RelativeRisks overwhelmingly similar across risk groups? And if so, can we personalize care by applying relative risk to individual patients’ risk profiles? This key #EBM study demonstrates that the answer to both questions is an unquestionable YES.
