Study at a glance
Preclinical
pigs, tissue, tissues used to study cardiovascular and circulatory health.
Full text reports inhaled H₂-containing gas. Detected intervention quantities or schedules: 4%, 96%, 2%. · H₂-related quantities reported in the intervention passages: 4%, 96%, 2%. Values are not combined across different experimental arms.
Multiple article-specific time points; see the linked full methods.
Article-reported result excerpt (24 words maximum): “Before and after phlebotomy (T=-30 to T = 0), the mean (standard deviation) hemoglobin levels in the control and hydrogen groups decreased from 11.0…” 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. The article declares no conflicts of interest.

Some editorial classification fields are still pending. The source-reported outcomes and result are shown below; Hydrogenology does not infer a positive or negative signal from prose automatically.
Methods
pigs, tissue, tissues used to study cardiovascular and circulatory health.
Preclinical study; group or assay counts reported in the full text include n=10, n=5.
Multiple article-specific time points; see the linked full methods.
Full text reports inhaled H₂-containing gas. Detected intervention quantities or schedules: 4%, 96%, 2%.
Inhaled molecular H₂ at 4%; not classified as Brown’s gas without an H₂/O₂ composition.
H₂-related quantities reported in the intervention passages: 4%, 96%, 2%. Values are not combined across different experimental arms.
Not reported in the full article — an absolute H₂ flow in mL/min could not be verified.
O₂ concentration and absolute O₂ flow were not both reported in the full article; no value is inferred.
Control or comparison condition reported in the full article; see the linked methods for arm-specific details.
Outcomes and reported result
survival or mortality, inflammation and cytokines, 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. The article declares no conflicts of interest.
Applies to the reported animal, cell or tissue model, not directly to patients.
