I’m not posting this study because I find it immensely useful, but because I feel confident someone else will post it soon enough and it deserves caveating:
1. Health care staff using N95s self report lower compliance. Which of course they do, because N95 is uncomfortable (I expect many incoming posts about how N95s are dandy.)
2. N95s only work when appropriately fit. They are rarely that. So where this trial fails to find superiority, it’s worth noting that what it shows is “N95s as often used - that is, incorrectly - are no better than surgical masks.” Which, sure, yes, could’ve told you that.
