Analysis of agreement between measurements of continuous variables: general principles and lessons from studies of imaging of carotid stenosis.

Journal article

Clinical research often involves measurement of continuous variables. However, clinical measurements are seldom precise. It is frequently necessary, therefore, either for the reproducibility of measurements to be assessed (observer agreement studies), or for measurements made by different techniques to be compared (method comparison studies). There are numerous ways in which data can be analysed and reported in such studies, and several pitfalls. In order to determine which methods are common...
