A Critical Assessment of Some Recent Work on COVID-19
I tentatively re-analyze data from two well-publicized studies on COVID-19, namely the Charité "viral load in children" and the Bonn "seroprevalence in Heinsberg/Gangelt" study, from information available in the preprints.

The exercise may aid in placing these studies in the literature. With all caveats that apply to n=2 quickfire analyses based off preprints, one also wonders whether it illustrates inadvertent effects of "researcher degrees of freedom."
