Bias due to misclassification in the estimation of relative risk.
Copeland KT, Checkoway H, McMichael AJ, Holbrook RH. Copeland KT, et al. Am J Epidemiol. 1977 May;105(5):488-95. doi: 10.1093/oxfordjournals.aje.a112408. Am J Epidemiol. 1977. PMID: 871121
When misclassification is equal for the two compared groups, the estimate is biased toward the null value, and in some instances beyond; when differential misclassification occurs (as in selective recall in case-control studies) the bias can be in eith …

Effects of misclassification on estimates of relative risk in family history studies.
Szatmari P, Jones MB. Szatmari P, et al. Genet Epidemiol. 1999;16(4):368-81. doi: 10.1002/(SICI)1098-2272(1999)16:4<368::AID-GEPI4>3.0.CO;2-A. Genet Epidemiol. 1999. PMID: 10207718 Review.
Differential misclassification can bias the observed relative risk in either direction, depending on the different values of sensitivity and specificity among relatives of cases and controls. ...Although there are some methods available to correct the effects of non …

A sensitivity analysis of bias in relative risk estimates due to disinfection by-product exposure misclassification.
Wright JM, Bateson TF. Wright JM, et al. J Expo Anal Environ Epidemiol. 2005 May;15(3):212-6. doi: 10.1038/sj.jea.7500389. J Expo Anal Environ Epidemiol. 2005. PMID: 15226753
Misclassification bias from the use of unweighted town mean exposures ranged from 19 to 39%, increasing in proportion to the size of the true effect estimates. ...We observed a trade-off between bias and precision in the weighted exposure analyses, wit …

The effects of exposure misclassification on estimates of relative risk.
Flegal KM, Brownie C, Haas JD. Flegal KM, et al. Am J Epidemiol. 1986 Apr;123(4):736-51. doi: 10.1093/oxfordjournals.aje.a114294. Am J Epidemiol. 1986. PMID: 3953551
When there is misclassification of exposure, variation in P(E) may bias comparisons of relative risk between groups or exposures, either by producing spurious differences or by masking true differences, and may generate spurious trends associated with a third variab …

Use of predictive value to adjust relative risk estimates biased by misclassification of outcome status.
Green MS. Green MS. Am J Epidemiol. 1983 Jan;117(1):98-105. doi: 10.1093/oxfordjournals.aje.a113521. Am J Epidemiol. 1983. PMID: 6823958
The bias in relative risk estimates resulting from misclassification of outcome status has been shown to be a function of sensitivity and specificity of the classification procedure and of disease frequency. ...However, an estimate of the predictive va …

Relative-risk-estimate bias and loss of power in the Mantel test for trend resulting from the use of magnetic-field point-in-time ("spot") measurements in epidemiological studies based on an ordinal exposure scale.
Delpizzo V, Salzberg MR. Delpizzo V, et al. Bioelectromagnetics. 1992;13(5):363-78. doi: 10.1002/bem.2250130504. Bioelectromagnetics. 1992. PMID: 1445418
After classifying a number of houses on the basis of prolonged monitoring of the ambient, extremely low frequency (ELF) magnetic field, we determined the probability of misclassification for each "spot" measurement protocol. We calculated the effect of this misclassific …
