The degree to which scientists in one country collaborate with those in another can be measured by examining the addresses on each paper. On the SCI, this can be done electronically. Figure 6 shows the strength of collaboration between the UK and the four other nations studied. The co-authorship index reveals whether the UK's cardiovascular researchers collaborate with another country more than would be expected, given the total number of UK/foreign collaborations, and the number of papers produced by the UK and the country being studied. The higher the index, the stronger the association between the UK and that country. The intensity of UK collaboration with France and Germany is higher than expected, given the number of papers produced and co-authored by these 3 countries internationally. In contrast, collaboration between the UK and US was lower than expected given the volume of research activity in that country. This finding appears to suggest that the degree to which the UK collaborates with another country in cardiovascular research may be influenced by its geographic proximity.
