Does this mean that they excluded those who changed their opinion based on the test results? Or those that believed they had a novel infection after they had been tested?
- CryptoPunk 5y agoThey compared those who had COVID, as determined by antibody tests, and were not aware of having had COVID, to those who believed they had COVID, but had not had it, again according to antibody tests. This was to isolate the psychosocial impact on health of believing one has COVID from the direct biological effects of having COVID.

But: "...during the COVID-19 pandemic, *self-reported COVID-19* infection was associated *with most persistent physical symptoms*, whereas *laboratory-confirmed* COVID-19 infection was associated *only with anosmia*. ..." They all have been infected, but the ones self reported experienced much more symptoms of COVID infections that were longer persistent as with the other's, who had intentionally/unintentionally a positive lab test as their first confirmation of infection. That group experienced just anosmia.
- CryptoPunk 5y agoIt looks like they looked at both infected and not infected individuals: >>The crude prevalence of persistent physical symptoms was first calculated for 4 groups of participants according to both belief (ie, self-reported COVID-19 infection) and serology test results: belief negative and serology negative; belief positive and serology negative; belief negative and serology positive; and belief positive and serology positive.
