To establish whether there is a relationship between tobacco industry support of basic research and the conclusions drawn by the authors of that research.
A sample of 91 papers investigating the effects of tobacco or nicotine use upon cognitive performance was analyzed to see if the pattern of conclusions drawn by researchers acknowledging tobacco industry support differed from the pattern of conclusions drawn by researchers not acknowledging tobacco industry support.
Scientists acknowledging tobacco industry support reported typically that nicotine or smoking improved cognitive performance while researchers not reporting the financial support of the tobacco industry were more nearly split on their conclusions.
While it is only possible to speculate on the possible reasons, the existence of a possible bias in the published literature according to funding source must be given serious consideration.
确定烟草行业对基础研究的支持与该研究作者得出的结论之间是否存在关联。
对91篇研究烟草或尼古丁使用对认知表现影响的论文样本进行分析，以查看承认获得烟草行业支持的研究人员得出的结论模式是否与未承认获得烟草行业支持的研究人员得出的结论模式有所不同。
承认获得烟草行业支持的科学家通常报告称尼古丁或吸烟能改善认知表现，而未报告获得烟草行业资金支持的研究人员在结论上的分歧则更大。
虽然只能推测可能的原因，但必须认真考虑已发表文献中根据资金来源可能存在的偏差。
