Study at a glance
Preclinical
mice, rats, cells, cell used to study cardiovascular and circulatory health.
Full text reports H₂ dissolved in saline. Detected intervention quantities or schedules: 5 mL/kg, 72 hours, 2 hours, 1.73 mL, 100 mL, 6 mmol/L. · H₂-related quantities reported in the intervention passages: 5 mL/kg, 72 hours, 2 hours, 1.73 mL, 100 mL, 6 mmol/L. Values are not combined across different experimental arms.
72 hours
Article-reported result excerpt (24 words maximum): “Similar results were found in neurological scores, which were decreased significantly after SAH, and hydrogen-rich saline induction can significantly improve the neurological function (p<0.05,…” This excerpt is not a complete result summary; consult the linked full text for all positive and null findings.
Preclinical evidence only; findings do not establish a treatment effect in people. Funding or grant information is reported in the full article. No explicit conflict statement was identified in the machine-readable full article; absence is not inferred.

Preclinical study; group or assay counts reported in the full text include n=6.
72 hours
Full text reports H₂ dissolved in saline. Detected intervention quantities or schedules: 5 mL/kg, 72 hours, 2 hours, 1.73 mL, 100 mL, 6 mmol/L.
H₂ dissolved in saline — H₂ only unless the full text explicitly reports oxygen co-delivery.
H₂-related quantities reported in the intervention passages: 5 mL/kg, 72 hours, 2 hours, 1.73 mL, 100 mL, 6 mmol/L. Values are not combined across different experimental arms.
Control or comparison condition reported in the full article; see the linked methods for arm-specific details.
Outcomes and reported result
survival or mortality, clinical symptoms or functional scores, oxidative-stress and antioxidant markers, apoptosis or cell injury, histology or tissue damage, metabolic laboratory measures

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.
Limitations and applicability
Preclinical evidence only; findings do not establish a treatment effect in people. Funding or grant information is reported in the full article. No explicit conflict statement was identified in the machine-readable full article; absence is not inferred.
Applies to the reported animal, cell or tissue model, not directly to patients.
No single-study GRADE certainty rating is assigned. Read how records and evidence assessments are prepared.
