OBJECTIVE
To determine if there was statistically significant geographic variation in the number of authors on abstracts of the 1999 Radiological Society of North America (RSNA) Scientific Assembly.
METHODS
Information on type of presentation, number of authors listed in each presentation and country of origin was obtained for 2450 abstracts from the 1999 RSNA Scientific Assembly (1292 for scientific sessions, 1158 for scientific exhibitions).
RESULTS
In scientific sessions, there were significantly more multiauthor (> 6 authors) presentations from Japan (32%, p < 0.001) and Germany (19%, p = 0.004) than there were from North America (United States and Canada) (11%). There were also significantly more multiauthor scientific exhibitions from Japan (29%, p < 0.001) than from North America (9%). Overall, the percentages of multiauthor presentations from Japan (30%, p < 0.001) and Germany (18%, p < 0.001) were significantly higher than those from North America (10%).
CONCLUSION
There seems to be significant geographic variation in the number of authors credited on scientific presentations.
目的
确定1999年北美放射学会（RSNA）科学大会摘要的作者数量是否存在具有统计学意义的地域差异。
方法
获取了1999年RSNA科学大会2450篇摘要的相关信息，包括报告类型、各报告列出的作者数量以及作者的原籍国（科学会议1292篇，科学展览1158篇）。
结果
在科学会议中，来自日本（32%，p<0.001）和德国（19%，p = 0.004）的多作者（>6位作者）报告显著多于北美（美国和加拿大）（11%）。来自日本的多作者科学展览（29%，p<0.001）也显著多于北美（9%）。总体而言，来自日本（30%，p<0.001）和德国（18%，p<0.001）的多作者报告百分比显著高于北美（10%）。
结论
科学报告中署名的作者数量似乎存在显著的地域差异。
