This table shows the output from a multivariable regression analysis in which Anxiety and Depression mean score differences across the study were the dependent variables. Overall fit of the model was R2 = 0.030, p = 0.013 (Model A) and R2 = 0.040, p = 0.003 (Model B). “Beta" is the standardized regression coefficient. Numbers in ‘bold’ indicate significant results. Backward regression method was used.
