Extent of review: Link preserved methodological application records; no current clinical-content reassessment or external-link verification was performed.

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

No new calculations, hypothetical examples, effects, CIs, regrading, independence certification, dosing, product, eye-health, surgery, postoperative-care or dry-eye treatment instructions are created.
Referenced methods: Preserved C/E/H application conditions concerning questions, populations, interventions, comparators, reports versus studies, endpoints, denominators and harms were referenced.

N27 · What are the boundaries for long-term/rare harms and other populations?

Current findings: The existing safety description retains the limitation that 60-day postoperative completer results cannot establish long-term safety in people with milk-protein allergy, other illnesses or medicines.
Verification status: Unverified
Materials actually read: Stored summary read; external abstracts, full texts, registration, protocols and SAPs unread
Why unverified: The selected claim, parent material and reports are distinguished and transferred from the stored summary. Detailed original material is unverified and review of existing content remains incomplete. This does not establish completed clinical review or certification.
Reason for missing information: Long-term exposure/follow-up, harms surveillance, risk groups, medicines, group denominators, CIs and actual events are needed. No new treatment, intake, surgery or care instructions are given.
Required materials and conditions: Original duration; illnesses; medicines; long-term scope
Materials to obtain first: Long-term exposure/follow-up, harms surveillance, risk groups, medicines, group denominators, CIs and actual events are needed. No new treatment, intake, surgery or care instructions are given.
Further research: Material needed: Long-term exposure/follow-up, harms surveillance, risk groups, medicines, group denominators, CIs and actual events are needed. No new treatment, intake, surgery or care instructions are given. This records needed materials; no new research was executed.
Remaining uncertainty: External original material is unread and review of existing content remains incomplete. Original grades, scores, axes, historical verification and independence statements are not treated as new verdicts or certification.
Conditions for verification: Material for Original duration; illnesses; medicines; long-term scope must be linked to the selected subclaim, parent context, original report, test units, times, comparator and denominators, distinguishing unread external material.
Why this condition is needed: This condition connects Original duration; illnesses; medicines; long-term scope with the selected question, actual surgical population, oral intervention, routine-care control, tests and symptoms, time points, people and eyes, denominators and harms.

N28 · What material would trigger a sheet update?

Current findings: This table transfers stored material on day-60 postoperative tear-film tests. Relevant observations can be updated after content review of original tables, measures, times, people, eyes, denominators, actual controls, concurrent care, follow-up, support and harms.
Verification status: Partly verified
Materials actually read: Stored summary read; external abstracts, full texts, registration, protocols and SAPs unread
Why unverified: The selected claim, parent material and reports are distinguished and transferred from the stored summary. Detailed original material is unverified and review of existing content remains incomplete. This does not establish completed clinical review or certification.
Reason for missing information: Complete prechange text and records of condition versions, separate application and content review are needed. Added material, revised conditions and verdict changes remain separate events; no new research, calculations or regrading are executed.
Required materials and conditions: Distinguishing conditions, observations, original material and verdict changes
Materials to obtain first: Complete prechange text and records of condition versions, separate application and content review are needed. Added material, revised conditions and verdict changes remain separate events; no new research, calculations or regrading are executed.
Further research: Material needed: Complete prechange text and records of condition versions, separate application and content review are needed. Added material, revised conditions and verdict changes remain separate events; no new research, calculations or regrading are executed. This records needed materials; no new research was executed.
Remaining uncertainty: External original material is unread and review of existing content remains incomplete. Original grades, scores, axes, historical verification and independence statements are not treated as new verdicts or certification.
Conditions for verification: Material for Distinguishing conditions, observations, original material and verdict changes must be linked to the selected subclaim, parent context, original report, test units, times, comparator and denominators, distinguishing unread external material.
Why this condition is needed: This condition connects Distinguishing conditions, observations, original material and verdict changes with the selected question, actual surgical population, oral intervention, routine-care control, tests and symptoms, time points, people and eyes, denominators and harms.
