Yeah, it "might" do something. Why would they say that, without backing it up with any explanation? Is that an agenda of their own?
What about their own conclusion:
In our systematic review, we identified 10 RCTs that reported estimates of the effectiveness of face masks in reducing laboratory-confirmed influenza virus infections in the community from literature published during 1946–July 27, 2018. In pooled analysis, we found no significant reduction in influenza transmission with the use of face masks.
Does that matter? Why not talk about that conclusion? "Looking at other studies, the conclusion is there is no significant reduction with masks, but hey, ya never know, it 'might' actually do something anyways..." LOL. Yeah, that holds a lot of weight ;)
