Figure 7.

Depressive symptoms measured using the Yesavage test at baseline (pre-) and at the end of the trial (post-intervention) in both groups (CG and EG). The bars show the average level of depressive symptoms observed in each group at each time-point, and the error bars represent the standard deviation. The p-values for the decrease in depressive symptoms reduction obtained in each group are shown. Regression coefficients for experimental group (βEG), for the interaction between group and baseline score (βEG:bl) and respective 95% confidence intervals and p-values are displayed.
