• Statistically significant improvements are seen for ICU admission, hospitalization, recovery, cases, and viral clearance. 9 studies from 8 independent teams in 6 different countries show statistically significant improvements in isolation (3 for the most serious outcome).
• Meta analysis using the most serious outcome reported shows 63% [27‑81%] improvement. Results are similar for Randomized Controlled Trials, similar after exclusions, similar for peer-reviewed studies, and similar after excluding studies using combined treatment.
• Studies typically use advanced formulations for greatly improved bioavailability.
• While many treatments have some level of efficacy, they do not replace vaccines and other measures to avoid infection. Only 44% of quercetin studies show zero events in the treatment arm. Multiple treatments are typically used in combination, and other treatments may be more effective.
• No treatment, vaccine, or intervention is 100% available and effective for all variants. All practical, effective, and safe means should be used. Denying the efficacy of treatments increases mortality, morbidity, collateral damage, and endemic risk.
