Outcome type

Not reported in this record.

Reported in the source

Methods at a glance

Population or model

cell, mice, tissue, cells used to study other neurological conditions.

Sample

Preclinical study; group or assay counts reported in the full text include n=29, n=14, n=15, n=8, n=7.

Duration

60 days

Intervention

Full text reports another explicitly administered H₂ intervention. Detected intervention quantities or schedules: 3%, 60 days, 1 µM, 5 days, 1%, 4%, 15 min, 100 µM, 30 min, 5 min.

Hydrogen form

another explicitly administered H₂ intervention — H₂ only unless the full text explicitly reports oxygen co-delivery.

H₂ specification

H₂-related quantities reported in the intervention passages: 3%, 60 days, 1 µM, 5 days, 1%, 4%, 15 min, 100 µM, 30 min, 5 min. Values are not combined across different experimental arms.

H₂ flow

Not applicable — no inhaled H₂ intervention was identified in the full article.

O₂ delivered with H₂

No inhaled O₂ co-delivery was identified for this non-inhalation intervention.

Comparator

Control or comparison condition reported in the full article; see the linked methods for arm-specific details.

Reported, not endorsed

Outcomes and reported result

Outcomes measured

survival or mortality, clinical symptoms or functional scores, inflammation and cytokines, oxidative-stress and antioxidant markers, apoptosis or cell injury, metabolic laboratory measures

Reported result

Article-reported result excerpt (24 words maximum): “In the test trial on day 6, the escape latency time of the H_2-treated 5xFAD mice decreased by a factor of 6.0 ( p…” This excerpt is not a complete result summary; consult the linked full text for all positive and null findings.

Results-extraction completeness

The complete machine-readable article was checked for source identity, methods, intervention quantities, results, tables, funding and conflict declarations. This public record is based on the full article.

A reported association, difference or mechanism is not automatically a clinical benefit. Null findings, outcome type, study design and precision all matter.

Interpretation limits

Cautions and applicability

Design and reporting cautions

Preclinical evidence only; findings do not establish a treatment effect in people. Funding or grant information is reported in the full article. The article declares no conflicts of interest.

Applies directly to

Applies to the reported animal, cell or tissue model, not directly to patients.

Preliminary appraisal framework

Not reported in this record.

Preliminary risk-of-bias status

Not reported in this record.

Appraisal rationale

Not reported in this record.

No single-study GRADE certainty rating is assigned. Certainty is assessed by important outcome across a complete eligible evidence set, not by attaching a final grade to one source.
