Of central importance is the screening instrument's Positive Predictive Value (PPV), which is itself influenced by the prevalence of the condition. When PPV exceeds prevalence, screening defines a screen-positive group with a higher prevalence to which diagnostic-stage procedures can be targeted, a necessary component of a screening program's potential for cost-effectiveness. METHODS: Employing the best available estimates of the prevalence of PND we applied Bayes' Theorem to map the parameter space for the Positive Predictive Value of the..
