Human and clinical studies

Selected human-study records are shown with their indexed or reviewed study type. Check the original article for the intervention, formulation and controls; the molecule can also be a comparator or measured variable.

No matching human study was retained in this selected bibliography. This is a documented evidence gap in our selection, not proof that no study exists.

Preclinical research, reviews & other publications

Animal studies, laboratory experiments, reviews and other indexed papers answer different questions. A review is secondary evidence; a case report does not estimate how often an outcome occurs.
