We specified the prevalence as equal to 22%%, value chosen in line with the prevalence of cannabis use estimated in Europeans (European Monitoring Centre for Drugs and Drug Addiction, 2012).
SSe can be estimated from the maximum number of infected carcasses expected under the specified design prevalence, and the sensitivity of the test applied.
For threshold t, P Q ≥ t) = k where k is the specified population prevalence of disease.
Public health policies are evaluated in terms of confidence expressed as robustness to modeling error in achieving specified TB prevalence at the target time.
Three studies of women aged 20 years or younger reported estimates of 5.7 13.7% [ 60, 61, 65], and three further studies where age was not specified reported prevalence estimates of 2.8% [ 59], 3.9% [ 66] and 12.3% [ 68].
EPP Classic and r-trend create a specified low prevalence of HIV infection (0.0025%) in a start year that varies over a specified range of possible years, whereas r-spline allows the prevalence level of this initial pulse of infection to vary, but uses a fixed start year.
After setting probabilities and costs under each diagnostic strategy, we then created a flexible modeling structure capable of generating epidemiological scenarios as a function of three variables, which the user specifies: HIV prevalence (assuming a global mean level of antiretroviral therapy coverage), TB incidence, and MDR-TB prevalence among new TB cases.
Nevertheless, epidemiologic studies in Africa should be carried out to specify the prevalence and geographic distribution of all HDV clades.
Among the few countries with national programs to routinely screen pregnant women for hepatitis B by specifying HBeAg prevalence are, e.g. the Netherlands [ 18, 19].
