Finding and using research results to support your professional decisions must be a systematic process, based on the principles of evidence-based medicine and healthcare. This article takes you through a critical appraisal exercise using a recent article from the British Medical Journal as an example. It describes how you decide whether to read and use an article that may be relevant to your decision. The reading is guided by a series of questions. First you evaluate the validity of the article: is the study conducted and reported so that you may trust the results? The second set of questions discusses the outcomes, the effect of the intervention and describes the use of confidence intervals for this. The possibility of using the research results in the reader's setting and patient population is then evaluated.
寻找并运用研究结果来支持你的专业决策必须是一个基于循证医学和医疗保健原则的系统过程。本文以《英国医学杂志》最近的一篇文章为例，带你进行一次批判性评估练习。它描述了你如何决定是否阅读并使用一篇可能与你的决策相关的文章。阅读由一系列问题引导。首先，你评估文章的有效性：该研究的开展和报告方式是否能让你信任其结果？第二组问题讨论结果、干预措施的效果，并描述置信区间在此方面的运用。然后评估在读者所处环境和患者群体中使用该研究结果的可能性。
