Osteoarthritis: what the evidence supports and Glucosamine

Each entry’s own grades, side by side. A grade says how strong the evidence is for one outcome — it does not rank one entry over the other.

Osteoarthritis: what the evidence supports

5 graded interventions for osteoarthritis, ranked by strength of evidence.

Grade B5 graded outcomesrevised Jul 10, 2026

Assembled by the app from other entries in this library. It adds no evidence of its own — follow the links to the entries it draws on.

Compound or practice

Glucosamine

A joint mainstay with genuinely divided evidence — modest benefit at best, and a surprising cardiovascular-mortality observational signal in its favor.

Grade C2 graded outcomesrevised Jul 10, 2026

A structured monograph in Prometheus's bundled library. Its grades are the monograph's own reading of the evidence, not a peer-reviewed review.

Swap the two

Graded in both

Outcomes are matched by name. Two entries can describe the same outcome in different words, so one listed further down may still be graded in the other.

No outcome has the same name in both entries. They may still overlap under different wording — read the two lists below.
