组内相关系数（r1）被认为是一种统计方法，用于评估两种测量方法之间的一致性或一致性，并结合两种方法获得的平均值之间差异的显著性检验。我们表明，这两种技术都不适合评估测量方法的可验证性。我们描述了一种替代方法的基础上估计的平均值和标准偏差的差异测量的两种方法。
The intraclass correlation coefficient (r1) has been advocated as a statistic for assessing agreement or consistency between two methods of measurement, in conjunction with a significance test of the difference between means obtained by the two methods. We show that neither technique is appropriate for assessing the interchangeability of measurement methods. We describe an alternative approach based on estimation of the mean and standard deviation of differences between measurements by the two methods.
