How do they know how many of the control group were infected, but never tested?
This is addressed in the ‘strengths and limitations’ section of the discussion. I have copied the relevant text below:
Huh. Doesn’t really sound like they have a scientific basis for “very low prevalence”.
I don’t really know enough about Estonia to say, but if you think about it the worst under-reporting real cases in the non-infected cohort could do is minimize the effect size of not being effected as some of these individuals would actually also have the same health risks those who were infected have.
