NCT ID NCT06339450
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study aimed to see if a portable device could reliably collect breath samples from people with cystic fibrosis and healthy volunteers while they walked in parks or city streets. The goal was to measure certain substances in the breath that might show how the environment affects lung health. However, the study was withdrawn before enrolling any participants, so no results are available.
