Source and classification

What kind of evidence is this?

Evidence stream

Preclinical

Reported design

Controlled animal and cell study

Research topic

Skin, wound and aging research

Administration classification

Inhaled H₂

Study result signal

Not reported in this record.

Outcome type

Not reported in this record.

Reported in the source

Methods at a glance

Population or model

cells, mice, tissue, cell used to study skin, wound and aging research.

Sample

Preclinical study; group or assay counts reported in the full text include n=8.

Duration

24 hours

Intervention

Full text reports inhaled H₂-containing gas. Detected intervention quantities or schedules: 2%, 75%, 0.25 mmol/L, 24 hours.

Hydrogen form

Inhaled molecular H₂ at 75%; not classified as Brown’s gas without an H₂/O₂ composition.

H₂ specification

H₂-related quantities reported in the intervention passages: 2%, 75%, 0.25 mmol/L, 24 hours. Values are not combined across different experimental arms.

H₂ flow

Not reported in the full article — an absolute H₂ flow in mL/min could not be verified.

O₂ delivered with H₂

O₂ concentration and absolute O₂ flow were not both reported in the full article; no value is inferred.

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, tumor growth or cancer markers, inflammation and cytokines, oxidative-stress and antioxidant markers, apoptosis or cell injury

Reported result

Article-reported result excerpt (24 words maximum): “After exposure to 0.25 mmol/L H_2O_2, HUVECs showed a 2.5‐folds increase in the apoptosis rate, which was markedly reduced by H_2 pretreatment (especially 75%H_2)…” 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. No funding statement was identified in the machine-readable full article; absence is not inferred. No explicit conflict statement was identified in the machine-readable full article; absence is not inferred.

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.
