It may be behind a sign up wall but Medscape is free and you can fudge answers to the questions when signing up.
This, posted here by RB initially, although a preprint is a serious study 31+31 patients randomised controlled and (it seems on the study ticket) double-blind. Much, much better quality than the studies noted in the medscape review (preprint date was 30 march so they just missed it).
Very significant highly positive results. Only issue is this is for treatment from an initial mild presentation, so it does not show this will work for cases already acute when get to hospital.
