Statistically significant lower risk is seen for viral clearance. 2 studies from 2 independent teams in 2 countries show significant improvements.
Meta analysis using the most serious outcome reported shows 38% [5‑59%] lower risk. Results are better for Randomized Controlled Trials and higher quality studies and slightly worse for peer-reviewed studies.
Currently there is limited data, with only 835 patients and only 16 control events for the most serious outcome in trials to date.
4 RCTs with 323 patients have not reported results (up to 2 years late).
No treatment or intervention is 100% effective. All practical, effective, and safe means should be used based on risk/benefit analysis. Multiple treatments are typically used in combination, and other treatments may be more effective. Hydrogen Peroxide may be detrimental to the natural microbiome, raising concern for side effects, especially with prolonged or excessive use.
