Exploratory Analyses
Exploratory analyses showed several significant changes in caregiver involvement in medical support at M12, in financial assistance (M12, M24), and in medical decision support at M24 in the SIG. In the CG, the rates of caregivers providing help in medical decision support at M12, and in moral and emotional support at M12 and at M24 were significantly reduced compared to baseline. The rate of caregivers requesting professional and financial support was low, regardless of the allocation group. Only a slight increase in professional support was requested at M12 and M24 in the intervention group (data not shown).
