Study summary

Comparison of different screening score for hypoxemic OSA (Obstructive Sleep Apnea) with the results of a polysomnography (PSG). The different screening score studied are: STOP-BANG, DES-OSA, P-SAP and OSA50.

Read the detailed description

The investigators should compare the four screening scores (STOP-BANG, DES-OSA, P-SAP and OSA50) with the results of the PSG (and in particular the number of apnea and hypopnea index and the probability of hypoxemia).

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 6, 2016, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
