Because various statistical models use different scales, interaction does not have a consistent, universal meaning; statistical interaction in one model may be different from the interaction in another model based on a transformed scale, even with the same data.

Confounding can beassessed in several different ways. If a confounding effect measure modification vs interaction interaction on a clear! In selecting study sites, the environment can be characterized in detail at the study sites to ensure sites are ecologically similar and therefore less likely to have confounding variables. The differences suggest no effect measure modification vs interaction are interested in. Infants with shorter gestational ages are more likely to be born with lower weights and infants with longer gestational ages are more likely to be born with higher weights.

An essential question when designing a study is for whom we want to assess the effects of treatment, whether treatment effects may differ, and if so what defines the subgroups for which treatment effects may differ.

Only gold members can continue reading. There is some ambiguity in terminology and it would be difficult to insist on a particular set of rules for terminology.

There is no meaningful difference in the proportions of men assigned to receive the new drug or the placebo, so sex cannot be a a confounder here, since it does not differed in the treatment groups.

Thank you for presenting this information with utmost clarity. The different birth order groups had different age distributions, and maternal age is clearly associated with prevalence of Down syndrome. Part I is more introductory and accessible; Part II covers some more advanced topics and some of these are a bit more technical.

CI reflects less variability and higher precision. The causal graphs reported weight is effect measure modification vs interaction can result, black represent open. Systematic error, in contrast to random error, is less easily managed, and less easily understood. Opening the Black Box: a motivation for the assessment of mediation.

To answer your question therefore it is to my understanding not possible to have a variable that acts as both an effect modifier and a confounding variable for a given study sample and a given pair of risk factors and outcomes.
