The COVID-19 pandemic has prompted a historic global research effort to create a knowledge base that can guide mitigation strategies. This study uses the Scopus database to examine the literature published by Nigerian institutions since the outbreak of COVID-19, with a focus on bibliometric items, global collaboration, Scopus subject area classification, document types, active authors and institutions, journals, highly cited papers, and funding agencies.
We searched for articles indexed in the Scopus database between January 1st, 2020 and July 20th, 2022 using predetermined search terms. All article types and study designs were included.
During the period under consideration, researchers affiliated with Nigerian institutions published a total of 2,217 COVID-19 papers out of a total of 281,589 global outputs, implying that Nigerian institutions contributed 0.8% of total global COVID-19 scientific output. The majority of the documents published were articles/original research (n = 1,455, 68.4%). The National Institute of Health was the top funder, and the University of Ibadan was the most active institution. The vast majority of publications (38.3%) were in the field of health sciences, with 1197 papers in the medicine sub-category. The top journal was Pan African Medical Journal, which published 114 COVID-19 papers with at least one Nigerian institution affiliation. The most active collaborator with Nigerian institutions was the United States. With 745 citations, the most cited paper with at least one Nigerian institution affiliation was from the Nigeria Center for Disease Control.
Nigerian institutions have contributed to the scientific output of COVID-19. There is, however, a need to improve research capacity across all subject areas.
新冠疫情促使全球展开了一场历史性的研究工作，以创建一个可为缓解策略提供指导的知识库。本研究使用Scopus数据库来审视自新冠疫情爆发以来尼日利亚各机构发表的文献，重点关注文献计量指标、全球合作、Scopus主题领域分类、文献类型、活跃作者和机构、期刊、高被引论文以及资助机构。
我们使用预先确定的检索词，在Scopus数据库中检索了2020年1月1日至2022年7月20日期间收录的文章。纳入了所有文章类型和研究设计。
在研究期间，尼日利亚各机构的研究人员在全球总计281,589篇相关产出中，共发表了2217篇关于新冠疫情的论文，这意味着尼日利亚各机构贡献了全球新冠疫情科学产出总量的0.8%。发表的文献中，大多数是文章/原创研究（n = 1455，占68.4%）。美国国立卫生研究院是最大的资助者，伊巴丹大学是最活跃的机构。绝大多数出版物（38.3%）属于健康科学领域，其中医学子类别有1197篇论文。排名第一的期刊是《泛非医学杂志》，该期刊发表了114篇有至少一个尼日利亚机构参与的新冠疫情相关论文。与尼日利亚机构合作最活跃的是美国。有至少一个尼日利亚机构参与的被引次数最多的论文来自尼日利亚疾病控制中心，被引745次。
尼日利亚各机构为新冠疫情的科学产出做出了贡献。然而，有必要提高所有学科领域的研究能力。
