| 中文摘要: |
| 疫苗保护效果的真实世界研究是其上市后评价的重要内容，采用断点回归设计进行评价，可以克服随机对照试验的伦理学、现场组织实施等困难，结果更贴近现实，并可提供较高等级的因果推断证据。本文结合实例分析，对断点回归设计的原理、方法、应用场景及未来展望进行介绍与探讨，以期为新型冠状病毒疫苗保护效果的真实世界研究提供思路。 |
| 英文摘要: |
| Estimating the actual real-world effectiveness of the vaccine is an essential part of the post-marketing evaluation. This regression discontinuity design (RDD) using observational data is designed to quantify the effect of an intervention when eligibility for the intervention is based on a defined cutoff as age, making it suited to estimate vaccine effects. This approach can avoid the high cost and ethical issues; overcome difficulties in the organization and practice process in randomized controlled trials, which leads to a higher level of causal inference evidence and more realistic results. Here, we describe key features of RDD in general, and then specific scenarios, with examples, to illustrate that RDD are an essential tool for advancing our understanding of vaccine effects. |
