What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT01976052
Study groupRoleWhat they receive
Obstructive sleep apnea patientsPatients with obstructive sleep apnea that has not received CPAP treatment
Matched volunteers with non OSAMatched volunteers without OSA. Matched in respect to age and BMI
Matched normal controls with normal BMIVolunteers that are matched according to age but has a normal BMI

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Biomarker

    Biomarkers related to inflammation, hypoxia, oxidative stress, redox and the central nervous system will be measured

    Measured: Comparison between 0, 3 and 12 month

Secondary outcomes (3)
  1. Genomics

    Genomic screening by microarray

    Measured: Comparison between 0, 3, 12 month

  2. Apnea hypopnea index

    Apnea hypopnea index at 0, 3 and 12 month after treatment with CPAP in the obstructive sleep apnea groups

    Measured: Comparision between 0, 3 and 12 month

  3. Exhaled nitric oxide

    Measurement of exhaled nitric oxide

    Measured: Comparision at 0, 3 and 12 month

Questions about this trial

What is this clinical trial studying?

An observational study of Obstructive Sleep Apnea, run by Karolinska University Hospital at 1 site in Sweden.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 0 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Biomarker (time frame: Comparison between 0, 3 and 12 month). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Oct 2020.
