The evidence in words

The evidence map

This is the ranked evidence for benign prostatic hyperplasia: every compound in the knowledge base with a graded effect, best-supported first. Grades reflect replication and effect size, not popularity or marketing.

Best-supported

No intervention here reaches grade A or B — an honest reflection of how thin the evidence for benign prostatic hyperplasia still is.

Weaker or unproven
