病例对照研究中基于倾向得分的因果推断

研究问题
在按结果抽样的病例对照研究中,如何使用对照样本估计倾向得分,调整混杂并识别因果风险比等相对效应?
方法与思路
作者依托对照可交换性讨论三种设计,采用处理逆概率加权和双重稳健估计,并提出两步卡钳匹配及重叠诊断。
材料陈述的贡献
摘要称,三种病例对照设计下可用对照拟合的倾向得分估计相对效应,并新增匹配方法和两类必要重叠的诊断工具。
阅读关注点
核对三种抽样设计的目标总体、对照可交换性的准确含义,以及两类重叠条件和双重稳健性质各自需要什么。

原文摘要

Propensity score methods for causal inference are increasingly being used in cohort and experimental designs, but their development and uptake in outcome-dependent sampling schemes, such as case-control studies, remains limited. Case-control studies involve the sampling of individuals with and without an outcome of interest with the goal of estimating the effects of past exposures. When the design is observational, statistical adjustment for confounding bias is necessary. In case-control studies, propensity score models can be fit using control data under the assumption that the controls are representative of the source population with respect to their exposure distribution conditional on covariates ("control exchangeability"). In this paper, we first demonstrate that relative effects, such as causal risk ratios, are estimable under three different case-control design variants using control-fitted propensity scores. We appropriate two existing estimators for these designs: inverse probability of treatment weighting and an efficient and doubly robust estimator. We also introduce a novel two-step propensity score caliper-matching procedure for case-control designs. We introduce novel diagnostic tools to verify two necessary types of overlap. We then contrast our estimators using simulated data and apply them to examine the association between regular aspirin use and ovarian cancer risk.
