Breast reconstruction is an important aspect in breast cancer treatment.
A comprehensive search of MEDLINE, Embase, and the Cochrane Library of Systematic Reviews was performed. Systematic reviews and meta-analyses that focused on breast reconstruction and were published between 2000 and 2020 were included. Quality assessment was performed using A Measurement Tool to Assess Systematic Reviews (AMSTAR). Study characteristics were extracted, including journal and impact factor, year of publication, country affiliation, reporting adherence to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, number of citations, and number of studies included.
The average AMSTAR score was moderate (5.32). There was a significant increase in AMSTAR score ( < 0.01) and number of studies ( < 0.01) over time. There were no significant correlations between AMSTAR score and impact factor ( = 0.038), and AMSTAR score and number of citations ( = 0.52), but there was a significant association between AMSTAR score and number of studies ( = 0.013). Studies that adhered to the PRISMA statement had a higher AMSTAR score on average ( < 0.01).
Systematic reviews and meta-analyses about breast reconstruction had, on average, a moderate AMSTAR score. The number of studies and methodological quality have increased over time. Study characteristics including adherence to PRISMA guidelines are associated with improved methodological quality. Further improvements in specific AMSTAR domains would improve the overall methodological quality.
乳房重建是乳腺癌治疗的一个重要方面。
对MEDLINE、Embase和Cochrane系统评价图书馆进行了全面检索。纳入了2000年至2020年间发表的聚焦于乳房重建的系统评价和荟萃分析。使用系统评价评估测量工具（AMSTAR）进行质量评估。提取了研究特征，包括期刊和影响因子、发表年份、所属国家、报告对系统评价和荟萃分析首选报告项目（PRISMA）指南的遵循情况、引用次数以及纳入的研究数量。
AMSTAR平均得分中等（5.32）。随着时间的推移，AMSTAR得分（<0.01）和研究数量（<0.01）均显著增加。AMSTAR得分与影响因子（=0.038）以及AMSTAR得分与引用次数（=0.52）之间无显著相关性，但AMSTAR得分与研究数量之间存在显著关联（=0.013）。遵循PRISMA声明的研究平均AMSTAR得分更高（<0.01）。
关于乳房重建的系统评价和荟萃分析，平均而言，AMSTAR得分中等。研究数量和方法学质量随时间有所提高。包括遵循PRISMA指南在内的研究特征与方法学质量的提高相关。AMSTAR特定领域的进一步改进将提高整体方法学质量。
