For estimating reliable exposure-response relations it is necessary that random variation in both the response and the exposure variables be sufficiently small. Variability in cumulative exposures can arise from uncertainties in self-reported work histories from interviews. In most epidemiologic surveys, the information gathered from questionnaires is used without knowing the validity or reprod...
Introduction: Occupational exposure to carbon, silica, and quartz, particles are known predisposing factors for bronchial anthracosis.
