The results show the effect on reliability of exposure conditions, quality of concrete and design option according to the french design rules.
Study strengths include availability of serial urine samples collected over several years, allowing investigation of the reliability of exposure assessment over a substantially longer period than previously examined.
Polyphenol biomarkers could replace or complement traditional dietary assessment as a means of reducing self-reporting inaccuracies and improve the reliability of exposure measurements (45).
Reliability of exposure measures could not be calculated given that only 1 rater per location was used and that ratings were not repeated.
It involves identifying potentially hazardous practices or exposures in the workplace and assessing the extent to which they can be linked to workers, the effectiveness of controls, and the reliability of exposure measures [ 67].
The reliability of exposure measurements is limited by several factors, including the choice of exposure measured, how it relates to the relevant dose and/or biological pathway, and the method used to collect and analyze the sample, as well as the uncharacterized variability in exposure over time and place.
The relationship reported by Jacobson and Jacobson (1996) between PCB exposure and child IQ was not based on cord blood PCBs per se; rather, they maximized the reliability of exposure assessment by including maternal tissue compartments (maternal blood and breast milk) in their exposure metric, an approach somewhat similar to that reported here.
Although the association is generally stronger in studies in men compared with those in women, it is not clear whether this difference reflects the relatively low background risk of scleroderma in men, differences in exposure prevalence or in the reliability of exposure assessment (Messing et al. 2003), or a gender-related difference in susceptibility to the effects of TCE.
The main strengths of this study include the availability of reported agricultural pesticide use data and detailed crop maps near study residences, which combined with measured concentrations of pesticides in carpet dust samples from residences allowed us to evaluate the reliability of exposure classification in the context of epidemiologic studies.
The validity and reliability of the exposure opportunity index model have also been questioned on the basis of widely heterogeneous exposure estimates [ 96].
