What kind of evidence is this?
Preclinical
Controlled rat and cell study
Musculoskeletal and pain research
Other forms
Positive preclinical signal.
Bone-healing, tissue and mechanistic cell outcomes.
Methods at a glance
Ovariectomized rats with experimental fracture and related cell assays.
24 rats plus cell experiments.
Article-specific fracture-healing follow-up.
Hydrogen-rich saline/water during fracture healing.
H₂ dissolved in saline or water as described by the article.
The article reports approximately 1.6 ppm for the hydrogen preparation.
Not applicable.
No oxygen was co-delivered.
Fracture-model controls and hydrogen-treatment conditions.
Outcomes and reported result
Callus formation, bone measures, histology, autophagy and cell assays.
The hydrogen-treated condition was reported to have faster fracture-healing measures and altered autophagy-related signaling.
The full article was checked for methods, intervention details, outcomes, positive and null findings, funding and conflicts. This record does not imply medical efficacy.
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
Animal and cell evidence only; multiple mechanistic outcomes and incomplete blinding information.
The reported ovariectomized-rat fracture model only.
SYRCLE animal-study tool — preliminary
Some concerns
Controls were reported, but allocation concealment and blinded outcome assessment were unclear.
Sequence generation checked where reported · Allocation concealment generally unclear · Personnel blinding generally unclear · Outcome-assessor blinding generally unclear · No prospectively registered analysis plan identified
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.
