To review the published literature using propensity scoring, describe shortcomings in the use of this technique, and provide conceptual background for understanding and correctly implementing studies that use propensity matching.
We survey the published statistical literature and make recommendations for a set of standard criteria for studies that use propensity matching. We evaluated adherence to these criteria in recent publications in the Journal of Thoracic and Cardiovascular Surgery and determined how well the standards were applied.
We found that studies that use propensity matching are rarely documented well enough to be convincing in their results. When documentation is available, statistical shortcomings are common.
Improved statistical practice is needed when using propensity scoring. This article suggests standard criteria for using this method in Journal publications.
通过倾向评分回顾已发表文献，描述该技术应用中的缺陷，并为理解和正确实施使用倾向匹配的研究提供概念背景。
我们调查了已发表的统计文献，并为使用倾向匹配的研究提出了一套标准的建议。我们评估了这些标准在《胸心血管外科杂志》（Journal of Thoracic and Cardiovascular Surgery）近期出版物中的应用情况，并确定了这些标准的应用程度。
我们发现，使用倾向匹配的研究在结果的说服力方面记录得很少。当有记录时，常见的是统计上的缺陷。
在使用倾向评分时，需要改进统计实践。本文建议在期刊出版物中使用该方法的标准准则。
