Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:The present method has several limitations. First, we cannot estimate TIR or IFR for countries in which the pandemic is still expanding. Second, the theoretical ground for our key hypothesis (negative correlation between ER and IR) may be obscure. However, the extremely high correlation found in the countries where the pandemic is relatively well controlled supports the validity of our estimate. Comparing the present results with local surveys is interesting. Among European countries, a population-based study was conducted in Geneva, Switzerland and revealed 5 to 10% IR [4], which is much higher than our estimate of TIR for the whole Switzerland, 0.52%. Infected persons at the latest survey (June 13th) comprised 0.36% of the whole population of Switzerland (5.3% ER and 6.8% IR). When we divide the examined population into those up to the 3rd survey (May 16th) and those newly added between the 3rd and the latest surveys, each comprising 3.9% and 1.4% of the whole population, respectively, the IR was 9.0% for the former and 0.4% for the latter. The fact that the positive PCR rate is much lower for the recently expanded population supports our cardinal hypothesis. The 5–10% IR documented by the antibody survey [4] is inconsistent with the above figures. This may be due to the exceptionally high prevalence of COVID-19 in Geneva within Switzerland [10]. The reported IR in Tokyo, Japan, the most-densely infected region within Japan, varies from 0.10% (antibody tests) [7] to 6% (PCR...
