无对照组两时点数据的重抽样因果推断及健康风险应用

研究问题
健康研究只有个体基线与随访观测、没有平行对照组时,如何利用重抽样和匹配估计干预及相关风险因素的因果效应?
方法与思路
作者提出 I-Rand,对每名个体独立抽取两个时点之一,再结合匹配方法进行效应估计与推断,并应用于低碳水饮食干预数据。
材料陈述的贡献
摘要称该方法在临床观测数据中发现肥胖风险和低碳水饮食的显著关联效应,并提供实现代码;其因果解释仍需核对识别依据。
阅读关注点
应重点核对没有对照组时如何排除时间趋势、混杂与其他同期变化,以及时点抽样、匹配和重复重抽样如何支持效应推断。
阅读边界
所据为 arXiv 预印本,同行评审与期刊接收未核实;摘要未列明因果识别假设和效应数值,抽样程序本身不能证明干预因果性。

原文摘要

Two-point time-series data, characterized by baseline and follow-up observations, are frequently encountered in health research. We study a novel two-point time series structure without a control group, which is driven by an observational routine clinical dataset collected to monitor key risk markers of type-$2$ diabetes (T2D) and cardiovascular disease (CVD). We propose a resampling approach called 'I-Rand' for independently sampling one of the two time points for each individual and making inference on the estimated causal effects based on matching methods. The proposed method is illustrated with data from a service-based dietary intervention to promote a low-carbohydrate diet (LCD), designed to impact risk of T2D and CVD. Baseline data contain a pre-intervention health record of study participants, and health data after LCD intervention are recorded at the follow-up visit, providing a two-point time-series pattern without a parallel control group. Using this approach we find that obesity is a significant risk factor of T2D and CVD, and an LCD approach can significantly mitigate the risks of T2D and CVD. We provide code that implements our method.
