Time-adjusted Analysis Shows Weak Associations Between BCG Vaccination Policy and COVID-19 Disease Progression	2020-05-06		.txt	text/plain	3861	176	49	In this study, we ascertain the associations between BCG vaccination policies and progression of COVID-19 through analysis of various time-adjusted indicators either directly extracted from the incidence and death reports, or estimated as parameters of disease progression models. The associations between BCG vaccination policy and COVID-19 disease progression have also been a subject to controversy in data analysis, with some studies claiming significant effects on the number of cases and case fatality rates (Miller et al., 2020; Berg et al., 2020) , while others criticizing weaknesses of those studies and claiming no statistically significant differences (Szigeti et al., 2020; Hensel et al., 2020; Fukui et al., 2020; Singh, 2020) . In this study, we have estimated a variety of indicators characteristic for different stages of COVID-19 epidemics, also adjusting for time since the beginning of the epidemics in each country, and found that several key indicators show weak, but statistically significant, associations with BCG vaccination status.	./cache/cord-344553-uya1j94u.txt	./txt/cord-344553-uya1j94u.txt
