Mediation analysis with case-control sampling: Identification and estimation in the presence of a binary mediator
病例对照抽样下二元中介分析的识别与估计
With reference to a stratified case-control procedure based on a binary variable of primary interest, we derive the expression of the distortion induced by the sampling design on the parameters of the logistic model of a secondary variable. This is particularly relevant when performing mediation analysis (possibly in a causal framework) with stratified case-control data in settings where both the outcome and the mediator are binary. Our identification result opens the way to…
