Conclusion
ADVERSE EVENTS
This phase II trial did not show a clinically important difference in physical outcomes between the intervention and control groups. However, the intervention group exhibited a trend toward a clinically important improvement in the mental aspects of HR‐QoL compared with the control group. Furthermore, program adherence was good, and adverse events related to the intervention were not observed. These preliminary data indicate that a phase III trial focusing on the mental aspect of HR‐QoL (as the primary outcome) is feasible.
