Methods at a glance
Adults with chronic hepatitis B receiving routine treatment; a separate group of 30 healthy participants provided reference measurements.
185 patients were recruited, 101 met eligibility criteria and 84 were randomized to routine treatment n=41 or routine treatment plus hydrogen-rich water n=43. Only 30 participants in each randomized group were included in the final analysis.
Six consecutive weeks. The Methods describe consumption three times daily, while the abstract says twice daily; the source does not reconcile this discrepancy.
Routine hepatitis-B treatment plus 1,200–1,800 mL/day of hydrogen-rich drinking water for six weeks.
H₂ dissolved in drinking water — H₂ only, not Brown's gas.
Hydrogen-rich water was made with a metallic magnesium stick; the reported final dissolved-H₂ concentration was 0.55–0.65 mmol/L.
Not applicable — drinking water, not gas inhalation.
No O₂ was co-delivered as part of the intervention.
Routine hepatitis-B treatment without added hydrogen-rich water; the healthy group was a non-randomized reference group.
Outcomes and reported result
Serum superoxide dismutase, glutathione S-transferase, xanthine oxidase and malondialdehyde, liver-function tests and HBV DNA.
Oxidative-stress markers improved more with hydrogen-rich water than with routine treatment alone. Liver-function measures and HBV DNA improved within both patient groups, but did not differ significantly between the randomized groups after treatment.
The complete open-access article, recruitment and attrition, randomization, water preparation, concentration and volume, positive and null results and reporting inconsistencies were checked.
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
Short trial with major post-randomization attrition: 24 of 84 randomized participants were excluded from the final analysis. The article's abstract says 60 patients were randomized although the Results show 84 randomized and 60 analyzed, and twice-daily dosing in the abstract conflicts with three-times-daily dosing in Methods. Masking and allocation procedures are sparsely described. No dedicated funding or conflict-of-interest statement was identified in the checked article, so absence of funding or conflicts is not inferred.
Adults with chronic hepatitis B receiving the study's routine background treatment; the trial did not show an added liver-function or viral-load benefit.

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.
