> The final study population comprised 341 participants (90.6% females) who completed blood sampling and answered the questionnaire. A total of 232 (68%) were seropositive
How does this compare to the base rate in a similar population? Two thirds sounds like a reasonable estimate for "ever had COVID" in Denmark in 2022, though maybe a smaller percentage would in fact be seropositive. It would be interesting if self-reported long COVID had little or no correlation with having had COVID at all.
