Statistically significant lower risk is seen for hospitalization and cases. 4 studies from 4 independent teams in 4 countries show significant improvements.
Meta analysis using the most serious outcome reported shows 39% [14‑56%] lower risk. Results are similar for Randomized Controlled Trials and higher quality studies.
Currently there is limited data, with only 37 control events for the most serious outcome in trials to date.
2 RCTs with 664 patients have not reported results (up to 2 years late)1,2.
