Outcomes
Primary outcome [1]
0
0
The AHI difference between the test device (Somfit) and gold standard (PSG)
Query!
Assessment method [1]
0
0
AHI is the apnea hypopnea index, main measure of presence/severity of OSA (obstructive sleep apnea). it will test the null hypothesis that Somfit AHI is not equivalent to the AHI reported by PSG
Query!
Timepoint [1]
0
0
Data required for the primary outcome measure are generated in the course of single night sleep recording for every participant. Statistical estimation will be performed after completion of all sleep recordings
