Critical review of original studies is a major source of medical information for the physician; it necessitates a clear understanding of the research objective of the study. The design of the study, whether experimental or observational, should be appropriate to answer the research question and, further, the study should employ accurate and precise measurements on a suitable group of subjects. The critical reader, aware of the principle of study design and analysis, can assess the validity of the author's conclusions through careful review of the article. A guide to the analysis of an original article is presented here. The reader is asked to formulate questions about a study from the abstract. The answers to these questions, which form the basis for acceptance or rejection of the author's conclusions, are in general available in the body of an article. This technique is demonstrated with two fictional studies about patients with angina.
对原始研究进行批判性综述是医生获取医学信息的主要来源；这需要清楚地理解研究的目标。研究设计，无论是实验性的还是观察性的，都应适合回答研究问题，而且，研究应对合适的受试群体进行准确和精确的测量。熟悉研究设计和分析原则的批判性读者可以通过仔细阅读文章来评估作者结论的有效性。本文提供了一篇分析原始文章的指南。要求读者从摘要中就一项研究提出问题。这些问题的答案构成了接受或拒绝作者结论的基础，通常可以在文章正文中找到。用两项关于心绞痛患者的虚构研究来演示这项技术。
