As of 26 October 2026 · 13.5% of the library

A randomized controlled trial assigns people by chance to the practice or to a comparison group. That makes it easier to attribute a difference in outcome to the practice than other designs do. Meta-analyses combine several such trials. This page lists the practices graded on that basis, grouped by topic. A grade tells you the kind of evidence, not how large the benefit is. Read the caveat on each practice page before you rely on it.
