负对照暴露可用于检测甚至调整测量混杂因素控制后残留的混杂因素。一种新描述的方法允许分析人员通过使用负控制暴露来定义和选择一个亚队列,其中暴露者之间的U分布与未暴露者之间的U分布相似,从而减少未测量混杂因素U的残留混淆。在这里,我们证明了传统方法可以用来控制测量的混杂因素,并结合新的方法来控制未测量的混杂因素。我们还推导了应用这种方法后仍然存在的偏差的表达式。我们用“平衡”参数表示剩余偏置,并表明该参数由暴露和未暴露的u分布之间的总变分距离限定。这些措施描述并限定了使用负控制来调整未测量混杂因素后剩余混杂因素的程度,并对测量混杂因素进行常规控制。
Negative-control exposures can be used to detect and even adjust for confounding that remains after control of measured confounders. A newly described method allows the analyst to reduce residual confounding by unmeasured confounders U by using negative-control exposures to define and select a subcohort wherein the U-distribution among the exposed is similar to that among the unexposed. Here, we show that conventional methods can be used to control for measured confounders in conjunction with the new method to control for unmeasured ones. We also derive an expression for bias that remains after applying this approach. We express remaining bias in terms of a “balancing” parameter and show that this parameter is bounded by a summary variational distance between the U-distribution in the exposed and the unexposed. These measures describe and bound the extent of remaining confounding after using negative controls to adjust for unmeasured confounders with conventional control of measured confounders.
