Key findings

What ClinicalTrials.gov does not surface for Sleep Apnea on its own pages , computed from the registry mirror as of 2026-08-08. Each line carries its own denominator so it can be quoted as it stands.

  1. Sleep Apnea is recruiting above its size-band peers.

    16 of 37 indexed trials (43.2%) are open to enrollment, against a 39.7% average across 762 conditions with 20-99 trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. Sponsorship of Sleep Apnea trials is spread across many organizations.

    VA Office of Research and Development accounts for 3 of 37 trials (8.1%). 30 distinct sponsors appear on at least one study for this condition label.

  3. Typical Sleep Apnea enrolment sits around 100 participants.

    Median target enrolment is 100 among the 37 trials that report a genuine target (sentinel values excluded). 18 of those (48.6%) plan for fewer than 100 participants.

  4. Sleep Apnea research is mostly interventional.

    28 interventional and 9 observational studies make up this index (75.7% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
