  1. Implications of measurement error in exposure for the sample sizes of case-control studies.

    Article - En anglais

    In this paper, recent results describing the effects of measurement error on estimation of the association between an exposure and a disease are applied to sample size calculation in case-control studies.

    Models of the relation between true exposure and a surrogate exposure measure assessed with error are used to derive equations for sample size determination.

    The results show that the sample size of a study based on an exposure variable which is measured with error must be larger by a factor of 1/rhô2 than if exposure were measured without error, where rhô is the correlation between the true exposure and the surrogate exposure measure.
