How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Osteoporotic fracture rate (time frame: 5 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03344718, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
