理解调解对于确定介于暴露和结果之间的中介是有用的,当干预时,将阻断(部分或全部)暴露和结果之间的因果路径。传统流行病学中使用的中介方法已被用于理解分子中间体在高维组学数据情况下的作用,并取得了不同程度的成功。特别是,观察性流行病学研究的局限性,包括混淆、反向因果关系和测量误差,可能会影响传统的调解方法,并可能导致关于因果效应的错误结论。克服这些问题的分析中介的解决方案包括使用工具变量方法,如孟德尔随机化,这种方法可用于评估日益复杂的组学数据网络中的因果关系。
Understanding mediation is useful for identifying intermediates lying between an exposure and an outcome which, when intervened upon, will block (some or all of) the causal pathway between the exposure and outcome. Mediation approaches used in conventional epidemiology have been adapted to understanding the role of molecular intermediates in situations of high-dimensional omics data with varying degrees of success. In particular, the limitations of observational epidemiological study including confounding, reverse causation and measurement error can afflict conventional mediation approaches and may lead to incorrect conclusions regarding causal effects. Solutions to analysing mediation which overcome these problems include the use of instrumental variable methods such as Mendelian randomization, which may be applied to evaluate causality in increasingly complex networks of omics data.
