Source and classification

What kind of evidence is this?

Evidence stream

Preclinical

Reported design

Randomized blinded controlled study

Research topic

Cancer 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

mice, mouse, cell, cells used to study cancer research.

Sample

Preclinical study; the full text reports 6 mice, with group/assay counts including n=6, n=3.

Duration

375 mL/min

Intervention

Full text reports inhaled H₂-containing gas plus H₂ dissolved in drinking water plus topical or bath exposure to H₂-containing water. Detected intervention quantities or schedules: 100 ppm, 375 mL/min, 3%, 76%, 21%.

Hydrogen form

Inhaled molecular H₂ at 3%; oxygen co-delivery is reported.

H₂ specification

H₂-related quantities reported in the intervention passages: 100 ppm, 375 mL/min, 3%, 76%, 21%. Values are not combined across different experimental arms.

H₂ flow

11.25 mL/min H₂, calculated from 3% H₂ and 375 mL/min total flow reported in the full text.

O₂ delivered with H₂

21% O₂; 78.75 mL/min O₂ calculated from the reported total flow.

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): “These results suggest that inulin and H_2 exposure induce a similar antitumor effect through stimulation of immunosurveillance..” 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.
