A Randomized Controlled Trial for the Effectiveness of Progressive Muscle Relaxation and Guided Imagery as Anxiety Reducing Interventions in Breast and Prostate Cancer Patients Undergoing Chemotherapy

Table 1

Generalised Estimating Equations parameter estimates for the effect of intervention on depression and anxiety. The group by time interaction is verified for both scales. There is difference in the linear effect of time between intervention and control for the depression scale () and for the anxiety level ().
