title: [Measurement discrepancies (analysis of consistency between 2 methods)].
abstract: Our purpose was to study the agreement between two methods with clinical impact. Usually, many techniques are not correct for the analysis of concordance. Otherwise, it is normal to confuse association and concordance. We intend to prove that two methods can show a strong association and a weak concordance. Nowadays we must replace "old" methods with new ones, which are more correct and efficient for clinical and research goals.
