The correct approach to analyzing method agreement is discussed. Whether we are considering agreement between two measurements on the same samples (repeatability) or two individuals using identical methodology on identical samples (reproducibility) or comparing two methods, appropriate procedures are described, and worked examples are shown. The correct approaches for both categorical and numerical variables are explained. More complex analyses involving a comparison of more than two pairs of data are mentioned and guidance for these analyses given. Simple formulae for calculating the approximate sample size needed for agreement analysis are also given. Examples of good practice from the reproduction literature are cited, and common errors of methodology are indicated.
本文讨论了分析方法一致性的正确方法。无论是考虑同一样本上两种测量值之间的一致性(重复性),还是考虑同一样本上使用相同方法的两个人之间的一致性(再现性),还是比较两种方法,都描述了适当的程序,并展示了示例。解释了适用于分类变量和数值变量的正确方法。提到了涉及比较两对以上数据的更复杂的分析,并提供了这些分析的指导。还给出了用于计算一致性分析所需近似样本量的简单公式。引用了再现性文献中的良好实践示例,并指出了常见的方法学错误。
