NCT ID NCT04463719
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a digital conversation aid to help patients and doctors make shared decisions about thyroid biopsy. Researchers enrolled 107 adults with thyroid nodules to see if using the tool during clinic visits was practical. The goal was to gather information for planning a larger future study, not to directly treat or cure disease.
