Well I clicked on the link, and there are a ton of results totally irrelevant to the discussion.
However, near the top is the Danish RCT study on masks (the largest conducted so far), which concluded that they did not make a statistically significant difference in transmission. It would still benefit from a much wider study, however, and hopefully further research will be forthcoming.
The couple of papers there I looked at that seemed to say masks do make a difference said so on the provisio that they are medical-grade N95s used in controlled enviroments; obviously this is not the case with the masks used in the public.
However, let's not let this go into another mask discussion as the other thread was locked as it had been done to death. It's worth reading though for some insight, as
@Bantamzen says.
