title: [Comparison of methods estimating a quantitative parameter: evaluation of the agreement].
abstract: Many quantitative clinical, biological and radiological parameters are useful in medicine for guiding diagnosis and therapy. The nephrologists use such parameters on a daily basis, particularly to assess renal function. In order to use the measurement methods of these parameters in clinical practice, it is mandatory to establish the agreement of the values provided, comparatively to the value obtained by using the reference measurement method of this parameter. This review details the methodology for the validation of methods for estimating quantitative parameters.
