People, their families and healthcare professionals need realistic expectations about what to expect.
It appears that this is from October 2020 with some links updated in January 2021. So, it's nearly a year old. My citation is from November 2021. Surely we've learned a significant amount about COVID in 2021.
Of course, these days, anyone can link to a "study" about anything that says anything you want it to say.
I mean, i just took that study from the Wikipedia page on long covid.
What you linked may be valid, but so far has zero citations and various critical discussion going on in the comments. Is this already published at all or is it a preprint?
I don't have enough time or knowledge to assess the validity of the claims, but based on that, the study I found on Wikipedia seems more trustworthy to me.
