Model comparisons via likelihood ratio tests. The general model contains the interaction-terms of the predictors of a given model with the dummy-variables referring to groups. In the restricted model the regression weights of the interaction-terms are restricted to zero. For each QOL-variable the analysis is once conducted with a dataset containing the PGs and the CG and once with a dataset containing only the PGs.
