Risk factors associated with mortality of COVID-19 in 2692 counties of the United States	2020-05-21		.txt	text/plain	2509	162	62	A county health ranking and roadmaps program has been established to identify factors associated with disparity in mobility and mortality of COVID-19 in all counties in the United States. Design: A negative binomial design was applied to the county-level mortality counts of COVID-19 on April 15, 2020 in the United States. In this design, the infected counties were categorized into three levels of infections using clustering analysis based on time-variant cumulative confirmed cases from March 1 to April 15, 2020. We collected the number of cumulative confirmed cases and total deaths from March 1 to April 15, 2020, for counties in the United States from the New York Times(9). Residential segregation between non-White and White in was the significant factor associated with the mortality of COVID-19 across the three classes of counties as shown in Figure 3 .	./cache/cord-270238-5esd2eti.txt	./txt/cord-270238-5esd2eti.txt
