摘要: 队列研究提供的病因证据在各种观察性研究设计中具有最高的质量，最重要的原因之一是其先"因"后"果"的设计原理。因此，随访是队列研究的核心要素之一，有效的随访方法是队列研究质量的重要保障。本文简要介绍了队列研究中关于随访期的考虑，随访队列的两种主要方法及其各自的优缺点。

Abstract: The cohort study provides the strongest evidence of causality among observational epidemiological study design. One of the most important reasons is that cohort study more clearly indicates the temporal sequence between exposure and outcome. Effective and efficient follow-up is the fundamental necessity for research quality. This review briefly introduces the requirements for the observation period of the cohort study, the two most common ways for follow-up and their advantages and disadvantages.
