Issues and pitfalls in method comparison studies


Hartnack, Sonja (2014). Issues and pitfalls in method comparison studies. Veterinary Anaesthesia and Analgesia, 41(3):227-232.

Abstract

Method comparison studies are needed for validation
of new methods of measurements, for example, noninvasive
blood pressure measurements against standard reference methods. After a brief introduction into method comparison studies, this paper is organized in three sections. The first section deals with the widely, though not always appropriately, used classical Bland-Altman plot with the limits of agreement and its extensions with non-constant bias and multiple observations. The second section comments
on other statistical approaches including correlation coefficients, linear regressions and sensitivities
and specificities which are sometimes seen in method comparison studies. The third section proposes the usage of linear mixed effects models as a flexible way to deal with questions associated with method comparison studies.
