Paired Binary Data with Predictor (139 General Practitioners)

Abstract

Paired proportions have to be assessed when e.g. different diagnostic procedures are performed in one subject. McNemar’s chi-square test is appropriate for analysis. Mc Nemar’s test can not include predictor variables. The analysis of paired outcome proportions including predictor variables requires the module generalized estimating equations. The difference between the two outcomes and the independent effects of the predictors variables on the outcomes are simultaneously tested.
