effect modificationheterogeneity of effectinteractionsynergismThe term effect modification has been applied to two distinct phenomena. For the first phenomenon, effect modification simply means that some chosen measure of effect varies across levels of backgroun...

Effect modification and interaction are terms often used in medical research. However, the analysis of effect modification and interaction has differing objectives. These two phenomena require different methods of analysing and presenting. Effect modification means that the association under study differs be...

The scale of interaction: Additive and multiplicative interactions Definitions and basic terminology In moderation analysis, binary outcomes have led to an increased focus on the fact that measures of interaction and effect modification are scale-dependent; thus, it is possible to find different answers...
To improve this, we provide four steps, template tables and examples. We distinguish two cases: when the causal effect of intervening on one exposure, across strata of another factor, is of interest ('effect modification'); and when the causal effect of intervening on two exposures is of ...
an interaction (or effect modification) is formed when a third variable modifies the relation between a risk and outcome. 简述一遍流程: 先判断是否是intercation,再判断是否是confounding effect。 如果我们想要探究【抽烟&血压】的关系,这里【性别】作为3rd variable。

em: TRUE, for effect modification assessment. FALSE, for interaction. recode: If TRUE, recodes the exposures - if at least one of the exposures is protective - such that the stratum with the lowest risk becomes the new reference category when the two exposures are considered jointly (See Knol...
Three kinds of calcium sulfate whisker (CSW) and two types of asphalt binders were used to prepare the modification asphalt by mechanical stirring. The influence of the types and contents of CSW on the high temperature performance, deformation resistance property, temperature susceptibility performance,...
