Disparate Effect Of Missing Mediators On Transportability of Causal Effects

arXiv:2403.08638v1 Announce Type: new
Abstract: Transported mediation effects provide an avenue to understand how upstream interventions (such as improved neighborhood conditions like green spaces) would work differently when applied to different populations as a result of factors that mediate the effects. However, when mediators are missing in the population where the effect is to be transported, these estimates could be biased. We study this issue of missing mediators, motivated by challenges in public health, wherein mediators can be missing, not …
