Cough is a prominent symptom of many allergic diseases and a major health burden but there is little information available on the current state of research in this area.
To analyze long-term developments in cough research and recent trends.
We searched the Thomson Reuters Web of Science databases for cough-related items published between 1900 and 2007 and analyzed the results using scientometric methods and density-equalizing calculations.
We found 12 960 cough-related publications from 132 countries for the period studied. The most productive country was the United States of America (USA), followed by the United Kingdom (UK), France, Japan, Canada, and Germany. These 12 960 published items were cited 165 868 times. The average number of citations per item increased from 1976 to 1992, with peaks in 1977, 1979, 1981, 1984, 1989 and 1992. Each of these years was followed by a decrease in citation numbers. Bilateral and multilateral cooperation analysis using the radar chart technique showed a progressive increase in international co-authorship starting at the beginning of the 1990s, with a leading role by the USA and the UK.
We detected a marked increased in cough-related research starting in the 1990s. While the majority of data originates from the US, other countries have taken a leading position in terms of research quality (number of citations per item).
咳嗽是许多过敏性疾病的突出症状，也是一项重大的健康负担，但关于该领域当前的研究状况，可获取的信息很少。
分析咳嗽研究的长期发展情况和近期趋势。
我们在汤森路透科学网数据库中检索了1900年至2007年间发表的与咳嗽相关的文献，并使用科学计量方法和密度均衡计算对结果进行分析。
在研究期间，我们发现来自132个国家的12960篇与咳嗽相关的出版物。产出最多的国家是美国，其次是英国、法国、日本、加拿大和德国。这12960篇已发表的文献被引用了165868次。每篇文献的平均被引用次数在1976年至1992年间有所增加，在1977年、1979年、1981年、1984年、1989年和199年达到峰值。这些年份之后，引用次数均有所下降。使用雷达图技术进行的双边和多边合作分析表明，从20世纪90年代初开始，国际合著情况逐渐增加，美国和英国发挥了主导作用。
我们发现从20世纪90年代开始，与咳嗽相关的研究显著增加。虽然大多数数据来自美国，但在研究质量（每篇文献的被引用次数）方面，其他国家已占据领先地位。
