The comparison of two quantitative measuring devices is often performed with the Limits of Agreement proposed by Bland and Altman in their seminal Lancet paper back in 1986. Sample size considerations were rare for such agreement analyses in the past, but recently several proposals have been made depending on how agreement is to be assessed and the number of replicates to be used. We have summarized recent developments and recommendations in various situations including a distinction between method comparison and observer variability studies. These include current state-of-the-art analysis of and reporting guidelines for agreement studies. General recommendations close the paper.

两种定量测量设备的比较通常使用 Bland 和 Altman 在其 1986 年的开创性柳叶刀论文中提出的一致性限制。过去，这种一致性分析很少考虑样本量，但最近根据不同情况提出了一些建议关于如何评估一致性以及要使用的重复次数。我们总结了各种情况下的最新发展和建议，包括方法比较和观察者变异性研究之间的区别。其中包括当前最先进的协议研究分析和报告指南。一般建议关闭本文。
