Statistically significant lower risk is seen for mortality and recovery. 3 studies from 3 independent teams in 3 countries show significant improvements.
Meta analysis using the most serious outcome reported shows 17% [-3‑34%] lower risk, without reaching statistical significance. Results are similar for peer-reviewed studies and worse for Randomized Controlled Trials.
6 RCTs with 1,092 patients have not reported results (up to 3 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 are significantly more effective.
