6.4.1. Introduction

The Mantel-Haenszel strategy has a useful application to the analysis of repeated measurements data. Such data occur when measurements are obtained over time; when responses from experimental units are measured under multiple conditions, such as multiple teeth in the same subject; and when multiple measurements are obtained from the same experimental unit, such as from two or more observers. Using repeated measurements enables comparisons among different times or conditions to avoid being obscured by subject-to-subject variability.

By specifying the appropriate tables for the data, you construct a setting in which Mantel-Haenszel methods can address the hypothesis of ...
