Pilot Study Report

Two randomized controlled trials were conducted: one for OSAS (obstructive sleep apnea syndrome) and one for Rhonchopathy, each with 95 participants. The dropout rate was below 10%, and the observation period was 3 months starting in April 2023. The Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS) were used to measure outcomes.

At time 0, the mean scores of ESS of the control groups in both studies (OSAS and Rhonchopathi) are almost equal to the mean ESS score in the intervention groups. Throughout the study, the mean ESS scores in the control groups remained almost the same at time 2. The mean ESS scores in the intervention groups improved significantly till time 2.

This difference between control groups and intervention groups is statistically significant.

At time 0, the mean scores of PSQI of the control groups in both studies (OSAS and Rhonchopathie / UARS) are almost equal to the mean ESS score in the intervention groups. Throughout the study, the mean ESS scores in the control groups remained almost the same at time 2. The mean ESS scores in the intervention groups improved significantly till time 2.

This difference between control groups and intervention groups is statistically significant.
