## What the statuses mean

- Partly verified: Some information exists in the preserved review summary; detailed original materials remain unverified. This does not certify a passed review or clinical efficacy.
- Unverified: Detailed materials for the selected condition could not be established within the stored scope; this does not mean zero effect, zero studies or safety
- Review incomplete: Review of existing content incomplete
- Met: Use only within the relevant conditions after existing content review; no automatic designation in this preparation
- Not reported: Distinguish only within materials actually read; do not turn unread external materials into unreported findings
- Inaccessible: Not applied during this preparation because actual access was not tested
- Not applicable: Use with a reason for non-applicability based on an explicit question boundary
- Conflicting data: Judge after actual material comparison; review was not performed during this preparation
- Insufficient evidence for the conditions: Do not use as a clinical grade encompassing currently unread materials
