Non-differential misclassification of exposure always leads to an underestimate of risk: an incorrect conclusion.
In most epidemiological surveys, there will be some errors of measurement or classification of exposure. For example, for a binary exposure variable, some exposed subjects may be classified as non-exposed, and some nonexposed subjects may be classified as exposed. Non-differential misclassification of exposure is present if, irrespective of disease, all exposed and non-exposed subjects have the...

متن کاملTesting an Assumption of Non-Differential Misclassification in Case-Control Studies
One of the issues regarding the misclassification in case-control studies is whether the misclassification error rates are the same for both cases and controls. Currently, a common practice is to assume that the rates are the same (“non-differential” assumption). However, it is suspicious that this assumption is valid in many case-control studies. Unfortunately, no test is available so far to t...
