临床医生经常需要知道一种新的测量方法是否等同于已经在临床使用的方法。本文回顾了方法比较研究的方法，以协助临床医生进行和评价这样的研究。来自1名受试者的温度数据用于说明程序。虽然人们不会根据1名受试者的发现做出决定，但数据集中大量的配对测量允许其用于说明目的。目前可用的软件消除了繁琐的统计计算的需要，但并没有减少理解方法比较研究的基本概念和准确解释结果的负担。
Clinicians often need to know whether a new method of measurement is equivalent to an established one already in clinical use. This article reviews the methodology of a method-comparison study to assist the clinician with the conduct and evaluation of such studies. Temperature data from 1 subject are used to illustrate the procedures. Although one would not make decisions on the basis of the findings from 1 subject, the large number of paired measurements in the data set permits its use for illustrative purposes. Currently available software eliminates the need for tedious statistical computation but does not reduce the burden of understanding the concepts underlying a method-comparison study and accurate interpretation of the findings.
