title: [Personnel standardization in clinical diagnosis of goiter: how to evaluate agreement among thyroid examiners?].
abstract: The use of the t Student and Cochran tests to evaluate central tendency measures, as well as the F test to evaluate variability and correlation analysis, have been incorrectly used for the evaluation of concordance between thyroid examiners. This paper presents the intraclass Kappa test (Bloch & Kraemer, 1989), as well as the experience of its use in Central America to standardize thyroid examiner personnel who participated in national surveys carried out during 1990 to determine goiter prevalence.
