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:<p>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.)<p>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.
