Study at a glance
Human
Human participants studied for respiratory health. See eligibility criteria in the linked full text.
Full text reports H₂ dissolved in drinking water. Detected intervention quantities or schedules: 300 mL, 95%, 8 mM, 250 mL. · H₂-related quantities reported in the intervention passages: 300 mL, 95%, 8 mM, 250 mL. 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): “Of the 10 patients, 7 showed improved oxygen saturation following four weeks of hydrogen therapy.” This excerpt is not a complete result summary; consult the linked full text for all positive and null findings.
Human evidence; design, sample size and comparator limit interpretation. No funding statement was identified in the machine-readable full article; absence is not inferred. The article declares no conflicts of interest.

Methods
Human participants studied for respiratory health. See eligibility criteria in the linked full text.
Human study; group or assay counts reported in the full text include n=7, n=2, n=1, n=10.
Multiple article-specific time points; see the linked full methods.
Full text reports H₂ dissolved in drinking water. Detected intervention quantities or schedules: 300 mL, 95%, 8 mM, 250 mL.
H₂ dissolved in drinking water — H₂ only unless the full text explicitly reports oxygen co-delivery.
H₂-related quantities reported in the intervention passages: 300 mL, 95%, 8 mM, 250 mL. 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, tumor growth or cancer markers, inflammation and cytokines, oxidative-stress and antioxidant markers, apoptosis or cell injury
Article-reported result excerpt (24 words maximum): “Of the 10 patients, 7 showed improved oxygen saturation following four weeks of hydrogen therapy.” This excerpt is not a complete result summary; consult the linked full text for all positive and null findings.
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
Human evidence; design, sample size and comparator limit interpretation. No funding statement was identified in the machine-readable full article; absence is not inferred. The article declares no conflicts of interest.
Applies only to the population and protocol reported in this respiratory health article.
