A meta-regression of global data from 160 countries	2020-09-05		.txt	text/plain	1170	90	57	RESULTS: The countries that had ≤70% coverage of BCG vaccine reported 6.5 (95% CI: −8.4 to −4.5) less COVID-19 infections per 10,000 population as compared to countries that reported no coverage. 3 Data on BCG vaccination status when analysed at a national-level along with incident cases of COVID-19, can give us an ecological idea of a possible protective effect, if any. 4 Data on BCG vaccination coverage was obtained from the WHO Global Health Observatory. 6 We included 160 countries that reported official data on BCG vaccination coverage (%) and COVID-19 confirmed cases until May 31, 2020. The countries that had ≤70% coverage of BCG vaccine reported 6.5 (95% CI: −8.4 to −4.5) less COVID-19 infections per 10,000 population as compared to countries that reported no coverage (p < 0.001). Irrespective of the level of coverage, the East Asia and Pacific region countries reported 4 less infections per 10,000 population, as compared to countries without BCG vaccination strategy.	./cache/cord-330203-7xen4nlm.txt	./txt/cord-330203-7xen4nlm.txt
