Study Population
Ten consecutive subjects referred for suspected OSA who met the inclusion criteria underwent full-night polysomnography. Patients were referred to the Tom McKendrick Sleep Laboratory, the Regional Sleep Centre for the province of Otago, by their general practitioners; ear, nose and throat surgeons; and other hospital physicians. Patients had self-reported symptoms that matched the range of symptoms common to OSA. They were initially assessed at an outpatient clinic, and the decision to conduct
Study Population
Ten consecutive subjects (2 women) who met the study criteria agreed to participate in the study. Demographic and anthropometric data are shown in Table 1. All subjects completed both arms of the study.
Clinical Outcomes
With the CMSC, mean AHI (± SD) was 26.9 ± 17.2/h slept. There was minimal overall reduction in the AHI compared to baseline (29.4 ± 13.4/h slept) [Table 2]. Treatment success with CMSC (AHI ≤ 10/h slept) was achieved in 2 of 10 subjects, partial success (AHI > 10 to ≤ 15/h slept) was achieved in
Discussion
In this study, we compared the effectiveness of a CMSC with standard nCPAP therapy in the management of OSA. AHI (≤ 10/h slept) was used as the primary outcome measure to define treatment success. We failed to demonstrate that the CMSC was an effective treatment. Only 2 of 10 patients responded successfully with the CMSC, and the mean AHI for this group did not change (mean AHI at baseline, 29.4 ± 13.4/h slept; mean AHI with CMSC, 26.9 ± 17.2/h slept). These results contrasted strongly with the

Comparative efficacy of CPAP, MADs, exercise-training, and dietary weight loss for sleep apnea: a network meta-analysis
2017, Sleep MedicineCitation Excerpt :Further details on methods (including assessment of study quality and PRISMA checklist) used are presented in Supplementary data. A literature search for four different interventions studied in this meta-analysis yielded four RCTs [16,19–21] comparing supervised aerobic exercise training to control and one [22] comparing exercise training to MADs and CPAP; six RCTs [23–28] comparing dietary weight loss to control; seven RCTs [29–35] comparing MADs to control, and eight RCTs [12,36–42] comparing CPAP and MADs; 50 RCTs [43–92] comparing CPAP to control as well as four RCTs [13,93–95] comparing CPAP and MADs to control in a three-arm trial design. Fig. A.1 shows the search strategy and selection process.
