They seem to be trying to argue that because air filtration units don't reduce CO2, they are not as good as opening the windows.
But that's a misunderstand of the use of CO2 as a proxy measure. #CovidIsAirborne
I hope Prof Reicher won't mind if I try to explore this further, because this is one of the things that has been so problematic (and toxic) in discussions around ME/CFS.
The problem here is that this has been weaponised by certain people to imply that it is those with ME who are doing the demeaning, by complaining that they have been told that it is "only in their mind".
It is the implication that is incorrect. Because those making the complaint are not demeaning mental health conditions, but are complaining about a misdiagnosis that means they will not be treated appropriately.
"Reassuring news" from a study that seems to make the same errors that other "reassuring" studies have made.
Not reassuring to those #LongCovidKids who've had #LongCovid for getting on for 2 years now @LongCovidKids@jneill
Ooooo. This study is riddled with misclassification bias. It has serious problems. They have done very little to exclude contamination of the controls, other than ask a question about whether kids had tested positive for covid.
