cord-170195-lrg11s5n	Stoye, Jorg	A Critical Assessment of Some Recent Work on COVID-19	2020-05-20		.txt	text/plain	2764	166	61	I tentatively re-analyze data from two well-publicized studies on COVID-19, namely the Charit'{e}"viral load in children"and the Bonn"seroprevalence in Heinsberg/Gangelt"study, from information available in the preprints. The authors focus on a hypothesis test as deliverable of their analysis; I would have recommended a nonparametric mean regression with error bands, resulting in some estimated age effect. To the statistically educated reader, the above headlines may suggest that the study tests, and fails to reject, H 0 : "Children have the same viral load as adults." It does not. To take an educated guess, I will now try to recover from the paper a test of H 0 : "Children have the same viral load as adults." To this purpose, I combine the first two and the remaining age bins of Figure 1 to find means of 4.74 and 5.21 with 95% confidence intervals of [4.42, 5.05] and [5.15, 5.27], respectively.	./cache/cord-170195-lrg11s5n.txt	./txt/cord-170195-lrg11s5n.txt
