Commenters are mostly overlooking the bidirectional element in the study.
A psychiatric diagnosis in the previous year was associated with a higher incidence of COVID-19 diagnosis (relative risk 1·65, 95% CI 1·59–1·71; p<0·0001)
Now THAT's interesting. Speculations about why? Are more anxious people more likely to get tested for covid? Depressed people more likely to not care about exposure?
