NCT ID NCT04572269
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study looked at whether chemicals in the blood (metabolomics) can help diagnose obstructive sleep apnea and track changes with treatment. Researchers analyzed stored blood samples from 388 people with and without sleep apnea, and also collected new samples from patients using CPAP therapy. The goal was to find a blood-based signature that correlates with sleep apnea severity and treatment adherence.
