A Practical Approach to Estimating the True Effect of Exposure Despite Imprecise Exposure Classification,
Abstract
Computation of relative risk of mortality or morbidity associated with exposure to some causative agent proceeds under the implied assumption that the exposure is measured with precision. In reality, accurate exposure information may or may not be obtainable. For instance, many survey that determine the smoking status of individuals in a population appear to do so with acceptable accuracy. However, occupational exposure to many toxic substances may be much more difficult to ascertain with similar accuracy. It is simply not practical to measure the actual exposure directly on a broad scale or on a continuous basis. Consequently, some form of indirect or surrogate measurement must be employed.
