It is crucial to conduct systematic reviews (SRs) and meta-analyses (MAs) to make causal references, in order to inform the clinical guidelines and decision-making. The high reporting quality of reviews through compliance with the guidelines Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Assessing the Methodological Quality of Systematic Reviews-2 (AMSTAR-2) could promote the consistency and reproducibility across the published articles. The purpose of this meta-epidemiological study is to evaluate the reporting methodological quality of SRs on the association between sleep duration and hypertension.
An electronic search in an online database was performed to retrieve systematic reviews and meta-analyses published up to 31st December 2022. Data screening and extraction were conducted by two investigators. The reporting quality of each included article was measured with reference to the 27-item 2020 PRISMA checklist, and methodological quality was evaluated using the AMSTAR-2. PRISMA evaluation was determined by total scores of individual SR and items scores and AMSTAR-2 assessment was also conducted using four categories.
Of 2269 articles captured in the initial search, 15 SRs were included in the final analyses. All SRs had more than one incomplete PRISMA item. The mean of total scores was 20.5 (range 14-25), and the results of the AMSTAR-2 assessment were critically low to low. The reporting quality of "rationale," "objectives," "selection process," "study selection," "discussion," and 'support' was fully reported. SRs that reported registration information and protocol had a higher PRISMA score than articles that reported certain deficiencies. From the results of the AMSTAR-2 assessment, the methodological quality of these SRs and MAs was critically low to low. None of the included literature provided a list of excluded articles, and the report of the search strategy was incomplete; half of the SRs did not use appropriate tools to assess the risk of bias in each included study.
Both the reporting and methodological quality of overall studies are less than ideal, with several key items being consistently under-reported. The quality measured by AMSTAR-2 is mainly consistent with the quality of reporting. Authors, reviewers, and journal editors should raise awareness and move forward to encourage completeness of SR reporting based on the results, which can aid in enhancing the quality of evidence.

为了提供临床指导和决策依据，进行系统评价（SR）和荟萃分析（MA）以进行因果推断至关重要。通过遵守系统评价和荟萃分析首选报告项目（PRISMA）和评估系统评价方法学质量-2（AMSTAR-2）的指南来提高综述的报告质量，可以提高发表文章的一致性和可重复性。本meta 流行病学研究的目的是评估关于睡眠时间与高血压之间关系的 SR 报告方法学质量。
对截至 2022 年 12 月 31 日在线数据库中发表的系统评价和荟萃分析进行电子检索。两名研究人员进行数据筛选和提取。参考 2020 年 PRISMA 检查表的 27 项条目，评估每个纳入文章的报告质量，并使用 AMSTAR-2 进行方法学质量评估。PRISMA 评估由个体 SR 的总分和条目得分确定，AMSTAR-2 评估也使用四个类别进行。
在最初的搜索中捕获了 2269 篇文章，最终分析纳入了 15 篇 SR。所有 SR 都有一个以上不完整的 PRISMA 条目。总分平均值为 20.5（范围 14-25），AMSTAR-2 评估结果为极低至低。“理由”、“目标”、“选择过程”、“研究选择”、“讨论”和“支持”的报告质量得到了充分报告。报告了注册信息和方案的 SR 比报告了某些缺陷的文章具有更高的 PRISMA 评分。根据 AMSTAR-2 评估的结果，这些 SR 和 MA 的方法学质量极低至低。纳入文献均未提供排除文章的列表，且搜索策略的报告不完整；一半的 SR 未使用适当的工具评估每个纳入研究的偏倚风险。
总体研究的报告和方法学质量都不理想，有几个关键项目始终未得到充分报告。AMSTAR-2 测量的质量主要与报告质量一致。作者、评论员和期刊编辑应根据结果提高认识并向前推进，鼓励基于 SR 报告的完整性，这有助于提高证据质量。
