From: SARS-CoV-2 genomic variations associated with mortality rate of COVID-19
Association of variant frequencies of SARS-CoV-2 with fatality rates of COVID-19 among 17 states in the United States. a Fatality rates in three different areas in the United States, Western, Central, and Eastern. Horizontal lines represent the means. The Student’s t test was used to evaluate statistical significance. b, c Correlation analysis between frequencies of SARS-CoV-2 ORF1ab 4715L (b) or S 614G variants (c) and fatality rates. Pearson’s correlation coefficients (r) were calculated
