Abstract

OBJECTIVES

The aims of this overview are to assess the trend of narrative and systematic reviews in Ethiopia, examine their methodological quality, and suggest future directions for improvement.

STUDY DESIGN AND SETTING

All narrative reviews and systematic reviews with or without a meta-analysis on topics associated with Ethiopia irrespective of the place of publication and authors' affiliation were included. The International Narrative Systematic Assessment for narrative reviews and A MeaSurement Tool to Assess Systematic Reviews for systematic reviews with or without a meta-analysis were used for quality appraisal. Fisher's exact test at the P-value threshold of 0.05 was used to investigate associated factors of methodological quality.

RESULTS

Of 106 articles reviewed, 54 (50.9%) were narrative reviews, 17 (16%) were systematic reviews, and 35 (33.1%) were systematic reviews with meta-analyses. Among 48 systematic reviews with or without meta-analysis, only five (10.4%) registered their protocol, four (8.3%) justified the selection of the study design for inclusion, and none of them reported sources of funding for the primary studies. Overall, 55.3% of narrative reviews and 75% of systematic reviews with or without meta-analysis had poor methodological quality.

CONCLUSIONS

Although publication rate of narrative and systematic reviews has risen in Ethiopia, half of the narrative reviews and three-quarters of the systematic reviews had poor methodological quality.

摘要

目的

本综述旨在评估埃塞俄比亚叙述性和系统性综述的趋势，检查其方法学质量，并为未来的改进提出建议。

研究设计和设置

纳入了所有与埃塞俄比亚相关主题的叙述性综述和系统综述，无论其出版地点和作者归属如何，同时包括了有或没有荟萃分析的系统综述。使用国际叙述性系统评估（用于叙述性综述）和评估系统评价的测量工具（用于有或没有荟萃分析的系统综述）进行质量评估。Fisher 精确检验用于研究与方法学质量相关的因素，P 值阈值为 0.05。

结果

在 106 篇综述中，54 篇（50.9%）为叙述性综述，17 篇（16%）为系统综述，35 篇（33.1%）为有荟萃分析的系统综述。在 48 篇有或没有荟萃分析的系统综述中，只有 5 篇（10.4%）注册了方案，4 篇（8.3%）对纳入研究设计的合理性进行了说明，没有一篇报告了主要研究的资金来源。总体而言，55.3%的叙述性综述和 75%的有或没有荟萃分析的系统综述方法学质量较差。
