Assessing agreement between skeletal and dental age estimation methods


When two different methods of measuring some quantity are compared, the aim is to find out whether the methods agree well enough for one method to support or replace the other. The product-moment correlation coefficient is often used but this approach is misleading. The correlation coefficient measures association and not agreement. In this paper the limits of agreement approach, also known as the Bland Altman method, is applied to assess the agreement between age estimates from radiographs of the wrist and the teeth.
