What is the methodological quality of studies about COVID-19 disease?
Study design:
This review article included 348 meta-analyses.
The first meta-analysis about COVID-19 disease was published on February 26, 2020 and the number of meta-analyses has grown rapidly since then.
Most of them were published in infectious disease and virology journals.
The greatest number comes from China, followed by the United States, Italy and the United Kingdom. On average, these meta-analyses included 23 studies and 15,200 participants.
Results and conclusions:
The investigators found overall quality of studies was remarkably low and only 8.9% of them could be considered as of high confidence level.
The investigators concluded although well-designed meta-analyses about COVID-19 disease have already been published, the majority are of low quality. Thus, all stakeholders playing a role in COVID-19 diseases, including policy makers, researchers, publishers and journals, should prioritize well-designed meta-analyses, performed only when the background information seem suitable and discouraging those of low quality or that use suboptimal methods.
