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 ...

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 regarding interaction depending on whether you are looking at the risk-difference scale (additive...
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...
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 ...
Here I show, in detail, how to write a regression equation that accounts for the effect modification. I explain how to interpret regression coefficients in models that account for the presence of effect modification, and I look at how this contrasts with effect modification interpretation in ...
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。
