A basic understanding of statistical methodology is essential, both for designing quality research projects and for evaluating the medical literature. Careful statistical planning, including the selection of study endpoints, the determination of the required sample size, and the selection of statistical tests to be used in the data analysis, is important to ensure a successful research project. The purpose of this article is to provide a basic review of statistical terms and methods for both the researcher and the clinician, as well as to clarify questions that need to be answered prior to embarking on an experimental study. The advantages of collaborating with statistical consultants, and some guidelines for such collaborations, are discussed as well.
对统计方法有基本的了解至关重要，这对于设计高质量的研究项目以及评估医学文献都是如此。精心的统计规划，包括研究终点的选择、所需样本量的确定以及数据分析中要使用的统计检验的选择，对于确保研究项目的成功很重要。本文的目的是为研究人员和临床医生提供统计术语和方法的基本综述，同时阐明在开展实验研究之前需要回答的问题。还讨论了与统计顾问合作的优势以及此类合作的一些指导原则。
