摘　　要：伞形评价中的文献重叠会影响研究结论的可靠性和准确性,产生偏倚风险较大的结果,因此评估文献重叠程度以及如何处理文献重叠变得非常重要。为了避免重复计算和减少偏倚风险,研究者需要量化文献重叠程度并采取相应的处理策略。本文详细介绍了文献重叠程度的计算方法以及处理重叠文献的不同策略,以期为国内学者对该方法的理解和应用提供参考和借鉴。The overlap of literature in umbrella reviews can affect the reliability and accuracy of research conclusions,leading to results with a higher risk of bias.Therefore,it becomes crucial to assess the degree of overlapping and how to handle it.In order to avoid redundant calculations and reduce the risk of bias,researchers need to quantify the degree of literature overlap and adopt corresponding processing strategies.This paper provides a detailed introduction to the calculation methods of overlapping and different strategies for handling overlapping,aiming to provide a reference and guidance for domestic scholars'understanding and application of this method.
