CFR comparisons between China and outside China. (A, B) CFR for COVID-19 in the indicated regions of China (panel A) or in the indicated countries (panel B) over time (from 23 January to 13 March 2020). (C) Difference analysis of CFRs in the early stages of COVID-19 outbreaks between China and outside China. CFRs in a period of 10-day, i.e., from 23 March to 1 February for China and other specific periods for countries outside China (for detail, refer to S1.xls file), were plotted as mean±SD at 95% confidence intervals (in the black box), with median being shown as short lines. Statistics were performed using SPSS with ANOVA algorithm, and significance levels (P value) for all the pairs are shown in Table S1. P values larger than 0.05 between Wuhan/Hubei and other countries are colored in red, indicating no significant difference (i.e., somehow being similar to each other) and the relative severity of the epidemic therein; P value between outside Hubei and South Korea is 0.55 (colored in blue), indicating relatively mild or controllable epidemic in South Korea.
