- Abstract
Classification of exposure into two levels—one consisting exclusively of unexposed individuals and the other consisting of exposed and perhaps unexposed ones—yields an unbiased estimate of attributable risk when misclassification is nondifferential. The authors advocate, therefore, the use of a broad definition of exposure when estimating attributable risk. Based on this idea, they justify a simple and robust method for estimating the overall attributable risk from several exposures that is based on a division of subjects into two groups, a baseline consisting of those unexposed to all exposures and everyone else.
