Temporal variation of time-delay adjusted case fatality risks (CFR) with unbiased CFR from 25th May 2020 to 28th February 2021 in Tokyo, Japan. The mean values of time-delay adjusted daily case fatality risks (CFR) from 25th May 2020 to 28th February 2021 are shown with a purple line. The shade region represents the 95% confidence intervals. The blue dot line shows the unbiased case fatality risk as 2.42% (95% credible interval: 2.41–2.43). If the time-delay adjusted daily CFR gets higher or lower, it is caused by random noises or other variables which have causal relationships. The unbiased case fatality risk plays a key role as a reference of the daily CFR.
