Single Institution, Bilateral, and Multilateral Collabortation Patterns (Institution Level) Area

Institutional collaboration modes for COVID-19 research. This graph is not cumulative. Papers are grouped by the week commencing on the dates given; the final week is incomplete. Publications counting toward ``single institution'' have only a single institutional affiliation, bilateral publications are affiliated with two institutions, and multilateral publications are those that are affiliated with more than two institutions. There is no sensitivity in this plot to the country in which institutions are situated.

新型冠状病毒肺炎（COVID-19）研究的机构合作模式。本图表并非累计式图表。论文以给定日期为起始日的周度时段进行分组；最后一周的数据尚不完整。被归入“单机构”类别的出版物仅拥有单个机构隶属关系；双边合作出版物拥有两家机构隶属关系，多边合作出版物则拥有两家以上的机构隶属关系。本图表的统计结果不受机构所在国家的影响。
