Meta analysis using the most serious outcome reported shows 24% [-24‑53%] lower risk, without reaching statistical significance. Results are worse for Randomized Controlled Trials and higher quality studies. Early treatment is more effective than late treatment.
3 studies from 3 independent teams in 2 countries show statistically significant improvements.
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 are more effective. The quality of non-prescription supplements can vary widely Crawford, Crighton.
