When a method comparison study is performed, the aim is to evaluate the agreement of measurements of different methods. We present the Bland-Altman plot with limits of agreement as the correct analysis methodology. We also discuss other scaled and unscaled indices of agreement and commonly used inappropriate approaches.
当进行方法比较研究时，目的是评估不同方法测量值的一致性。我们提出了带有一致性界限的 Bland-Altman 图作为正确的分析方法。我们还讨论了其他比例和非比例一致性指数以及常用的不适当方法。
