A Capture-Recapture Approach to Enhance Treatment Effect Evaluation in an Observational Cohort
利用捕获—再捕获方法改进观察队列中的处理效应评估
We extend recently proposed design-based capture-recapture (CRC) methods for prevalence estimation among registry participants, in order to enhance treatment effect evaluation among a trial-eligible target population. The so-called ``anchor stream design" for CRC analysis integrates an observational study cohort with a randomized trial involving a small representative study sample, and enhances the generalizability and transportability of CRC findings. We show that a novel…
