Direct assessment of completeness of ascertainment in a stroke incidence study.

Journal article

BACKGROUND AND PURPOSE: Validity of comparisons of stroke incidence between studies or time periods depends on the completeness of ascertainment. Ascertainment cannot be reliably assessed indirectly by statistical methods, such as capture-recapture. We report the first use of direct methods to determine the completeness of different ascertainment strategies in a population-based stroke incidence study (Oxford Vascular Study). METHODS: We assessed completeness of 2 different ascertainment str...
