The purpose of this article is to highlight important features of research design that clinicians can use to determine which articles are useful when attempting to answer clinical questions and determine the best therapy for a particular patient. This article offers a systematic means of categorizing the quality of research reports for clinicians and clinical investigators. A recurring clinical theme of hygiene education is used to exemplify how phrasing the clinical question determines the type of study design that could be used. The article describes the continuum of research reports, and categorizes them by their inherent strengths and weaknesses. The report describes why the research designs in the supreme position of the research hierarchy, are the most valuable to clinicians seeking evidence that defines the best therapy for their patients.
本文的目的是强调研究设计的重要特征，临床医生在试图回答临床问题并确定针对特定患者的最佳治疗方法时，可以利用这些特征来判断哪些文章有用。本文为临床医生和临床研究人员提供了一种对研究报告质量进行分类的系统方法。以卫生教育中反复出现的临床主题为例，说明如何表述临床问题决定了可采用的研究设计类型。本文描述了研究报告的连续性，并根据其固有的优缺点对它们进行分类。该报告阐述了处于研究层次结构最高位置的研究设计，为何对寻求能为其患者确定最佳治疗方法的证据的临床医生最有价值。
