6/n The basic issue here is that you have to be VERY CAREFUL with your statistical models. If you just lump everything in together it can make the results a bit meaningless
7/n There's also a problem in this study that boils down to selection bias You see, the study wasn't looking at every person infected with COVID-19 It was looking at everyone who TESTED POSITIVE TO COVID-19
8/n This creates an issue known as selection bias. The group of people that is selected to be studied (due to who got a test for COVID-19 in Israel earlier this year) may not be representative of the population in crucial ways that could have biased the results
9/n For example, we know that asthma diagnoses are very variable by many characteristics, which may also make people more or less likely to go get tested for COVID-19 (young men, for example - lots of asthma, might avoid testing)pic.twitter.com/VvkzTdo93f
10/n It also makes correcting for confounding challenging, because we do not know which biases are influencing the SELECTION of participants
11/n Ultimately, it's a bit hard to say more than that people with asthma were less likely to have a positive COVID-19 test in the group of people presenting for testing in Israel earlier this year
12/n While that's a bit less sensational than the headline, it's also a bit more truepic.twitter.com/LLhY2Dw0EK
13/n I should also note - the study itself is fine, generally, but the limitations section doesn't really discuss some of the biggest drawbacks of their methodology which I don't lovepic.twitter.com/iHFE2FPRyA
You put together a big enough data set you're going to get weird associations. Asthma result is likely due to unmeasured behavioral/pop differences between asthma pop and non-asthma pop, not the meds. My $.02.
Yeh I pretty much agree. 50k people is enough to throw up all sorts of spurious associations
