At the beginning of the development of meta-analysis, understanding the role of moderators was given the highest priority, with meta-regression provided as a method for achieving this goal. Yet in current practice, meta-regression is not as commonly used as anticipated. This paper seeks to understand this mismatch by reviewing the history of meta-regression methods over the past 40 years. We divide this time span into four periods and examine three types of methodological developments within each period: technical, conceptual, and practical. Our focus is broad and includes development of methods in the fields of education, psychology, and medicine. We conclude the paper with a discussion of five consensus points, as well as open questions and areas of research for the future.
元分析发展之初，理解调节变量的作用被置于最高优先级，元回归是实现这一目标的方法。然而，在当前实践中，元回归的使用并不像预期的那样普遍。本文通过回顾过去 40 年来元回归方法的历史，试图理解这种不匹配。我们将这段时间分为四个时期，并在每个时期内考察三种类型的方法学发展：技术、概念和实践。我们的关注点很广泛，包括教育、心理学和医学领域方法的发展。最后，我们讨论了五个共识点，以及未来的开放问题和研究领域。
