This paper focuses on the problems derived from the analysis of cross-over designs with binary dependent variables. In order to approach this analysis, we present those possibilities offered by a conditional exact logistic regression implemented to LogXact application. We illustrate the use of LogXact based on data from a study on decisions to take precautions against HIV infection in work environment. Besides the treatment effect, we simultaneously evaluate those effects of period and carry-over.
