Adjusted case fatality rate from COVID-19. Countries with 1 million (M) or more citizens were included in the analysis. The percentage of positive tests was used as a proportional correction factor for the infection prevalence in those countries in which 10% or more of the tests were positive (e.g., a country in which 25% of tests were positive was considered to be underestimating the infection prevalence by 2.5-fold). The red lines indicate the mean percent adjusted case fatality; ****P < 0.0001, ANOVA. Data are from August 12, 2020 (3).
