在meta分析和综述中纳入灰色文献是有争议的。我们研究了在meta分析中纳入灰色文献的优势和挑战。一项关于父母行为、孩子行为和父母调整结果的行为育儿干预的范例荟萃分析被用来证明这些问题。本文还探讨了纳入灰色文献对结果的影响，包括纳入灰色文献是否会影响效应大小，并描述了使用谷歌和Yahoo等传统搜索引擎搜索灰色文献的挑战。同质性和发表偏倚也被检查。基于这些结果，提出了对元分析和研究人员的建议。
The inclusion of grey literature in meta-analyses and reviews is controversial. We examine both the advantages and challenges of including grey literature in meta-analyses. An exemplar meta-analysis of behavioral parenting interventions on parent behavior, child behavior, and parent adjustment outcomes is used to demonstrate these issues. It also explores the influence of the inclusion of grey literature on outcomes, including whether effect sizes are affected by the inclusion of grey literature and describes the challenges of searching for grey literature using traditional search engines such as Google and Yahoo. Homogeneity and publication bias are also examined. Based on these results, recommendations are presented for meta-analysts and researchers.
