There may be a difference in the number of articles about COVID-19 and SARS-CoV-2 between low- and middle-income countries (LMICs) and high-income countries (HICs).
We analyzed authors' affiliations from 36 432 articles related to COVID-19 and SARS-CoV-2. We introduced logarithmic density and compared the number of articles and logarithmic density of LMICs with those of HICs.
The number of articles and the logarithmic density of LMICs were lower than those of HICs (p<0.0001 for both).
There was a disparity in the number of articles related to COVID-19 and SARS-CoV-2 between LMICs and HICs.
在低中等收入国家(LMICs)和高收入国家(HICs)中,关于 COVID-19 和 SARS-CoV-2 的文章数量可能存在差异。
我们分析了 36432 篇与 COVID-19 和 SARS-CoV-2 相关的文章的作者所属机构。我们引入了对数密度,并比较了 LMICs 和 HICs 的文章数量和对数密度。
LMICs 的文章数量和对数密度均低于 HICs(两者均 p<0.0001)。
在 COVID-19 和 SARS-CoV-2 相关文章的数量方面,LMICs 和 HICs 之间存在差异。
