Observational studies follow people or compare groups without assigning them the practice. They can show that a practice goes with a difference in outcomes, which is useful evidence. They cannot, on their own, show that the practice caused the difference. This page lists the practices graded on that basis, grouped by topic. Each practice has one grade, and each practice page states its caveat.
