  1. Calculation of mixed linear models with stepwise addition of parameters to assess the quality of the model and influence of the independent variables and covariates on the dependent variable CORSI. Covariance structure analysis: UN (unstructured covariance); AIC = Akaike information criterion; Sig. = 5% alpha level; time = visit 1 and 3.
