Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

Summary

This study looks at how sleep apnea measurements change from night to night. Current tests rely on a single night, which can be inaccurate. Researchers will track 192 people over multiple nights to find more reliable markers for diagnosis and treatment.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could identify more stable sleep apnea markers, improving diagnosis and treatment decisions.
What could go wrong
This is an observational study, not a treatment trial. It may not lead to immediate clinical changes.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Participants with suspected or diagnosed sleep-disordered breathing of any severity will be recruited at Inselspital University Hospital und University Bern. No selection or stratification based on sex, gender, or any other patient characteristics is applied during recruitment. Participants are included consecutively based on the clinical indication for home sleep apnea testing, irrespective of sex or gender. Any resulting imbalance reflects the underlying clinical population and does not compromise the scientific validity of the study, as analyses will account for sex and gender as covariates and report their effects transparently.
