Table 1 Demographics of the study groups. Supine Sleeping was calculated as the percentage of the total time in bed that was spent in supine position. Position dependency was assumed if more than 50% of all snores during the baseline night occurred in supine position. AHI and ODI have been obtained using the automatic scoring provided by the ApneaLink software (purchased from ResMed). Age, BMI, ESS, AHI, and ODI are reported as mean and standard deviation. All other values indicate the number of subjects
