Confounding in case control studies
I read with interest the article on computerized tests to evaluate psychomotor performance in children with specific learning disabilities (SpLD) by taur and colleagues1. the study was conducted with the aim to compare the performance on a battery of six psychomotor tests of children with SpLD and those without any learning disabilities (controls) using computerized tests. the authors deserve c...
متن کاملConfounding from Cryptic Relatedness in Case-Control Association Studies
Case-control association studies are widely used in the search for genetic variants that contribute to human diseases. It has long been known that such studies may suffer from high rates of false positives if there is unrecognized population structure. It is perhaps less widely appreciated that so-called "cryptic relatedness" (i.e., kinship among the cases or controls that is not known to the i...
متن کاملCase-Control Studies with Jointly Misclassified Exposure and Confounding Variables
The issue of 2 × 2 × 2 case-control studies is addressed when both exposure and confounding variables are jointly misclassified. Two scenarios are considered: the classification errors of exposure and confounding variables are independent or not independent. The bias-adjusted cell probability estimates which account for the misclassification bias are presented. The effect of misclassification o...
متن کاملControl for confounding in case-control studies using the stratification score, a retrospective balancing score.
The stratification score for a case-control study is the probability of disease modeled as a function of potential confounders. The authors show that the stratification score is a retrospective balancing score and thus plays a similar role in case-control studies as the propensity score plays in prospective studies. The authors further show how standardization using the stratification score can...
متن کاملMethodological issues of confounding in analytical epidemiologic studies
Background: Confounding can be thought of as mixing the effect of exposure on the risk of disease with a third factor which distorts the measure of association such as risk ratio or odds ratio. This bias arises because of complex functional relationship of confounder with both exposure and disease (outcome). In this article, we provided a conceptual framework review of confounding issues in epi...
