Long story short: they weren't. Of the 84,000 people who did the cognitive tests, only ~361~ reported having a confirmed case of COVID-19 That's, uh, not idealpic.twitter.com/18JzpMih74
Now, while this did represent the majority of hospitalized cases, it's still a bit of a problem for a paper looking at COVID-19 specifically to have very few cases of COVID-19 to examine!
