T130 85-460 Sentence denotes Our confidence in the pooled estimates of prevalence was reduced because of concerns of risk of bias (ie, selection bias, detection bias, and attrition bias), heterogeneity of the tested patient populations (inconsistency), as well as issues of indirectness (the majority of studies included primarily symptomatic hospitalized patients instead of all patients with COVID-19).
