Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With Freedom From SleepFlex-related Serious Adverse Events | 12 weeks | Number of participants with absence of serious adverse events related to the SleepFlex system. |
| Change in the Apnea-hypopnea Index (AHI) | 12 weeks | Change in the apnea-hypopnea index (AHI) on post-treatment vs. pre-treatment home sleep apnea test. Apneas are defined by \>=80% reduction in airflow for \>= 10 seconds in the presence of respiratory effort. Hypopneas are defined by \>=50% reduction in airflow with oxygen desaturation of \>=3% in the presence of respiratory effort. The Apnea-hypopnea index (AHI) is the sum of the apneas and hypopneas divided by the hours of recording time. AHI values are typically categorized as 5-15/hr = mild; 15-30/hr = moderate; and \>= 30/h = severe. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With Development of Side Effects: Mouth, Throat, or Neck Pain; Dysphagia | 12 weeks | Number of participants with development of the following potential side effects: mouth, throat, or neck pain; dysphagia. This was assessed repeatedly throughout the study. |

| Measure | Time frame | Description |

| Change in Supine AHI | 12 weeks | Change in the supine apnea-hypopnea index (AHI) on post-treatment vs. pre-treatment home sleep apnea test.The Apnea-hypopnea index (AHI) is the sum of the apneas and hypopneas divided by the hours of sleep. AHI values are typically categorized as 5-15/hr = mild; 15-30/hr = moderate; and \>= 30/h = severe. The supine position is defined by sleeping on one's back. |
| Change in Non-supine AHI | 12 weeks | Change in the non-supine apnea-hypopnea index (AHI) on post-treatment vs. pre-treatment home sleep apnea test.The Apnea-hypopnea index (AHI) is the sum of the apneas and hypopneas divided by the hours of sleep. AHI values are typically categorized as 5-15/hr = mild; 15-30/hr = moderate; and \>= 30/h = severe. The non-supine position is defined by sleeping in body positions other than one's back. Body position information is collected by the home sleep apnea test, and position-specific information is calculated. |

Outcome results
Change in the Apnea-hypopnea Index (AHI)
Change in the apnea-hypopnea index (AHI) on post-treatment vs. pre-treatment home sleep apnea test. Apneas are defined by \>=80% reduction in airflow for \>= 10 seconds in the presence of respiratory effort. Hypopneas are defined by \>=50% reduction in airflow with oxygen desaturation of \>=3% in the presence of respiratory effort. The Apnea-hypopnea index (AHI) is the sum of the apneas and hypopneas divided by the hours of recording time. AHI values are typically categorized as 5-15/hr = mild; 15-30/hr = moderate; and \>= 30/h = severe.
