The study compared two common types of masks to each other, to see how well they worked. That's all.
In order to address the question of whether they worked at all the study would have had to include a group with no masks, and it did not do that.
I'll repeat the conclusion in the post, which compared N95s to surgical masks: "...no statistically significant real-world performance difference between surgical masks, N95s"
And I'll quote from the article the post linked to: "Published in the Annals of Internal Medicine (AIM) this week and led by researchers at Canada's McMaster University, the study found no statistically significant difference in protection between the two kinds of masks in healthcare facilities in Canada, Israel, Pakistan and Egypt." https://justthenews.com/government/federal-agencies/highest-protection-rigorous-international-study-n95-masks-upends
If you think any study in that post or its links says that masks do not work at all I think you need to re-read them.
so, do the surgical masks work better than expected, or do the N95s work worse than expected?
What part of "the N95s are a smidge better than the surgical masks" is confusing you?
oh, I was lead to believe that the n95 masks were vastly superior to the surgical masks in terms of keeping out potential infectious particles, so seeing as the results are so close did the surgical masks excel or did the n95 masks fail?
Who led you to believe that? A research paper? A journal article? Some anonymous person on the Internet?
