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