Study design

The presentation introduces ReBloomLens for exercise and sleep self-management after breast cancer treatment. Eligibility is described as survivors in their 40s–60s who completed treatment for stage 0–3 breast cancer.

The design includes 40 participants: 20 intervention and 20 control, compared over four weeks. The planned intervention app-use period is 28 days. These figures are not reported here as completer counts or evidence of treatment effects.
