Note: *Changes in PCS total scores. The others are changes in T scores. Bolded values in the total (Pain-CBT and BIA group) column indicate a significant time effect in a post-hoc test and bolded values in the Pain-CBT and BIA column indicate a significant time by group interaction effect ( $p<$ 0.05).
