Summary

This study is following 1,000 people in Korea who have symptoms of sleep apnea, like loud snoring or feeling very tired during the day. The goal is to learn more about the condition and how well patients stick with breathing machine therapy. Participants will have sleep tests and regular check-ups, and some will donate blood samples for research.
