Exposure measurement error: influence on exposure-disease. Relationships and methods of correction.
Epidemiology, being primarily an observational rather than experimental science, has often encountered problems with measurement of the study variables, which are not under the control of the investigator. Difficulties arise in part because the variables under study are often subjective and often must be ascertained by subjects' self reports or from records of dubious quality, because biologica...

15 صفحه اولProject Summary Measurement Error Estimation and Correction Methods to Minimize Exposure Misclassification in Epidemiological Studies
This project summary highlights recent findings from research undertaken to develop improved methods to assess potential human health risks related to drinking water disinfection byproduct (DBP) exposures. The primary objective of this research was to examine the utility of routinely collected monitoring data to estimate individual-level exposures in epidemiological studies. Another specific ai...
متن کاملHome Endotoxin Exposure and Wheeze in Infants: Correction for Bias Due to Exposure Measurement Error
Exposure to elevated levels of endotoxin in family-room dust was previously observed to be significantly associated with increased wheeze in the first year of life among a cohort of 404 children in the Boston, Massachusetts, metropolitan area. However, it is likely that family-room dust endotoxin was a surrogate for airborne endotoxin exposure. Therefore, a related substudy characterized the re...
متن کاملComparing measurement error correction methods for rate-of-change exposure variables in survival analysis.
In this article we focus on comparing measurement error correction methods for rate-of-change exposure variables in survival analysis, when longitudinal data are observed prior to the follow-up time. Motivational examples include the analysis of the association between changes in cardiovascular risk factors and subsequent onset of coronary events. We derive a measurement error model for the rat...
