If a situation arose in which confounder measurement error differed across the subgroups, perhaps through different data collection procedures, then this would lead to confounder measurement error biasing the estimated genotype by exposure interaction.
The lack of an association between increased WHR and BC risk is again inconsistent with previous evidence (Connolly et al, 2002; Harvie et al, 2003), perhaps reflecting measurement error and a different effect of fat distribution in India compared to that in high-resource countries.
The absence of a negative correlation between dialkyl phosphate metabolites and ChE is perhaps partially caused by substantial measurement error in both measures.
Thus, we have ∼16 19% of the variation unaccounted for, but given that there is a small measurement error in the determination of A1C (perhaps 2 5%), and a larger coefficient of variation in the measurement of glucose (10 20%), the constraints imposed by methodology can explain the residual variation.
Hankins [ 22] has proposed that negatively worded items introduce additional variance to the model above that created through random measurement error and variations in the measured construct and that this perhaps results from an ambiguous response frame for these items.
While these ten measures might have suggested the presence of additional factors, their low communalities was perhaps more indicative of considerable measurement error or other sources of uniqueness in these variables (see Table S3).
Perhaps the most pervasive technical limitation is measurement error that varies depending upon the refresh rate of the monitor, the sampling rate of the input device, operating system activities, and the data acquisition software.
Perhaps of most concern is the problem of measurement error in dietary assessment, particularly associated with the use of FFQs in case-control studies.
However, studies have varied in their findings, perhaps for a number of factors, such as the specific components examined and differential measurement error among the components.
The gravest error, perhaps, was underestimating the risk of tsunamis.
