Our principal abstract measures have been the estimates together with ninety five% confidence intervals of the asymptomatic fraction. When estimates and ninety five% CIs of asymptomatic fractions weren’t reported within the research they were calculated from the variety of people contaminated and the variety of those that were asymptomatic, assuming a binomial distribution. The titles of all articles recognized by the search technique have been independently screened by two authors (N.H.L.L. and B.J.C.).
