Methods at a glance
rabbits, rabbit, mouse, tissue used to study eye health.
Preclinical study; the article does not state one consolidated sample total, so no total is inferred.
Multiple article-specific time points; see the linked full methods.
Full text reports another explicitly administered H₂ intervention. Detected intervention quantities or schedules: 2%, 0.2 mL/kg, 5%, 1 mL/kg, 1.6 ppm, 0.8 mM, 0.6 ± 0.1 ppm.
another explicitly administered H₂ intervention — H₂ only unless the full text explicitly reports oxygen co-delivery.
H₂-related quantities reported in the intervention passages: 2%, 0.2 mL/kg, 5%, 1 mL/kg, 1.6 ppm, 0.8 mM, 0.6 ± 0.1 ppm. Values are not combined across different experimental arms.
Not applicable — no inhaled H₂ intervention was identified in the full article.
No inhaled O₂ co-delivery was identified for this non-inhalation intervention.
Control or comparison condition reported in the full article; see the linked methods for arm-specific details.
Outcomes and reported result
clinical symptoms or functional scores, inflammation and cytokines, oxidative-stress and antioxidant markers, apoptosis or cell injury, histology or tissue damage, metabolic laboratory measures
Article-reported result excerpt (24 words maximum): “Because immunohistochemical, biochemical, and macroscopical results and results obtained with ultrasonic pachymeter of injured untreated corneas and corneas treated with PBS after purge of…” 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. Null findings, outcome type, study design and precision all matter.
Cautions 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.

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.
