It would be great to see what the prevalence of diseases in treated population is compared to that in the previously (pre-covid) untreated population, I expect that comparing against the currently untreated population could be problematic due to the higher incidence of covid in this population.
I feel that the paper (from a scan admittedly) is more a anecdotal listing of cases so I don't get a feel for whether the needle has shifted or not wrt autoimmune case incidence. While I think it's a great idea to look into the effects of the vaccination on folks, I also fear that the downside effects of anti-vaxxers waving this paper around out of context saying you see you shouldn't get vaccinated because you're going to have all these autoimmune issues.
