I have data with both between- and within-subjects Independent Variables (IV) and a multiple binary Dependent Variable (DV).

In order to determine the extent to which the IV influenced the DV, I performed a hierarchical binary logical regression with main effects as step 1, two-way interactions as step 2 and the three way interaction as step 3.

However, as my results revealed significant interactions, I want to compare specific proportions of my DV according to some IV (as planned t-test after a significant  ANOVA). I found that some authors used chi-squares to do that but I know that chi-squares are not suitable for within-subjects design.
Is there a specific analysis ? If no, is it possible to split my regression according to some IV?

Thank you in advance for your help!
