Sources and evidence assessment
A citation does not automatically make a claim certain. We assess what the study measured, who was studied, the uncertainty of the result and whether it applies to the user context being discussed.
Last updated:
Source priority
For broad effect claims, systematic reviews, meta-analyses, consensus statements and official guidance are preferred. A single study may be useful but is not treated as the final answer for an entire field.
- Title, authors, publisher and year are recorded when available.
- DOI or PMID identifiers are retained when available.
- Evidence type is an editorial classification, not an automatic truth score.
- Access dates may be shown for changing web sources.
Evidence and practical recommendations
Research may show an average association or effect in a controlled setting. A practical recommendation combines that evidence with the user’s goal, experience, schedule, equipment and recovery. It is labelled as a recommendation rather than a direct command from a study.
Communicating uncertainty
When evidence is conflicting, indirect or weak, this is stated. Treeniverstas does not fill evidence gaps with confident wording.
