“…On the other hand, exposure misclassification probably occurs in nearly every epidemiologic study.” Reviews of the effects of exposure measurement error and the numerous methods that have been proposed to correct for biases that result when exposure measurement error is present have been published (1, 8, 10, 26, 46). There have been many theoretical investigations of the effects of measurement error on point and interval estimates of exposure-disease associations, and the widespread and profound presence of exposure measurement error in environmental health data has been documented (6, 12, 14, 32, 45). Nevertheless, there have been few original scientific publications that make use of existing methods for explicit exposure measurement error correction in environmental or occupational health fields, in contrast, for example, to nutritional epidemiology where such corrections are becoming more common (16, 31, 49).…”
