Obstructive sleep apnea hypopnea syndrome: Protocol for the development of a core outcome set.

BACKGROUND Obstructive sleep apnea hypopnea syndrome (OSAHS) is a common, chronic sleep disease. As the incidence of OSAHS increases, it has seriously threatened people's health. There have been an increasing number of clinical trials of OSAHS in recent years. However, the clinical trials of OSAHS have heterogeneous outcomes, surrogate outcomes, subjective outcomes, and composite outcomes, as well as the lack of endpoints or patient perspectives. The best method is to develop a core outcomes sets (COSs) for OSAHS's clinical trials. METHODS The development of COSs of OSAHS will include 5 stages: RESULTS:: The results of our study will be published in a peer-reviewed journal. DISCUSSION The development of the COSs of OSAHS will improve the design and operation of OSAHS clinical trials to conform to international standards and ensure the credibility of the outcomes. In addition, this study will involve different stakeholder groups to help ensure that the developed COSs will be suitable and well accepted. TRIAL REGISTRATION NUMBER 1544.
