方法和结果选取了1999年4月1日至2000年3月31日期间发表在《内科学年鉴》、《英国医学杂志》、《美国医学会杂志》、《柳叶刀》和《新英格兰医学杂志》上的所有随机对照试验。我们关注随机对照试验，因为它们通常对临床医学有很大影响。如果试验是对先前发表的研究的后续分析，则不包括在内。摘要人员使用一个明确的抽象来记录研究支持的来源、作者-赞助者关系以及研究赞助者的角色。披露的作者与赞助者关系编码如下：顾问委员会、顾问/酬金、教育活动/演讲者局、就业、赠款、专利/许可和股票。拥有行业地址的研究作者被归类为雇员。
Methods and resultsAll randomised controlled trials published in each issue of the Annals of Internal Medicine, the BMJ, JAMA, the Lancet, and the New England Journal of Medicine from 1 April 1999 to 31 March 2000 were identified. We focused on randomised controlled trials as they often have great impact on clinical medicine. Trials were excluded if they were follow up analyses of a previously published study. An abstractor used an explicit abstraction to record source (s) of study support, author-sponsor relationships, and the role of study sponsor. Disclosed author-sponsor relationships were coded as follows: advisory board, consultant/honoraria, educational activities/speakers bureau, employment, grants, patent/licences, and stock. Study authors who had an industry address were categorised as employees.
