To evaluate the completeness of reporting abstracts of systematic reviews (SRs) before and after the publication of the PRISMA-A checklist in 2013 and to assess if an association exists between abstract characteristics and the completeness of reporting.
A systematic search of the literature was conducted in the PubMed and Scopus databases in March 2020. The search focused on the SRs of evaluations of interventions published since 2002 in the field of periodontology. The abstracts of the selected SRs were divided into two groups before and after publication of the PRISMA-A checklist in 2013, and compliance with the 12 items reported in the checklist was evaluated by three calibrated evaluators.
A set of 265 abstracts was included in the study. The total score before (mean score, 53.78%; 95% CI, 51.56-55.90%) and after (mean score, 56.88%; 95% CI, 55.39-58.44%) the publication of the PRISMA-A statement exhibited a statistically significant improvement (P = 0.012*). Nevertheless, only the checklist items included studies and synthesis of the results displayed a statistically significant change after guideline publication. The total PRISMA-A score was higher in the meta-analysis group and in articles authored by more than four authors.
The impact of the PRISMA-A was statistically significant, but the majority of the items did not improve after its introduction. The editors and referees of periodontal journals should promote adherence to the checklist to improve the quality of the reports and provide readers with better insight into the characteristics of published studies.
评估 2013 年 PRISMA-A 清单发表前后系统评价（SR）摘要报告的完整性，并评估摘要特征与报告完整性之间是否存在关联。
2020 年 3 月，我们在 PubMed 和 Scopus 数据库中进行了系统的文献搜索。搜索重点是自 2002 年以来发表的牙周病领域干预措施评价的 SR。将选定的 SR 摘要分为 2013 年 PRISMA-A 清单发表前后两组，由三位经过校准的评估人员评估清单中报告的 12 项内容的符合情况。
本研究共纳入 265 篇摘要。发表 PRISMA-A 声明前后（平均得分，53.78%；95%CI，51.56-55.90%），总分呈统计学显著提高（P=0.012*）。然而，仅清单中包含研究和结果综合这两项内容在指南发表后发生了统计学显著变化。在荟萃分析组和作者超过四位的文章中，PRISMA-A 总分更高。
PRISMA-A 的影响具有统计学意义，但大多数条目在引入后并未得到改善。牙周病期刊的编辑和审稿人应促进对清单的遵守，以提高报告的质量，并为读者提供更好地了解已发表研究的特征。
