Trial Outcomes & Findings for Vitamin D and Physical Activity on Bone Health (NCT NCT01419730)
NCT ID: NCT01419730
Last Updated: 2026-08-05
Results Overview
To collect preliminary data on the effects of vitamin D therapy and exercise (alone or in combination) on bone mineral density (BMD) as measured by a dual energy X-ray absorptiometry (DXA) in non-metastatic breast cancer patients who began hormonal therapy within the previous 12 months. Amount of bone loss was measured with change in BMD.
