Efficacy of SGLT2 inhibitors, GLP-1 receptor agonists, and aerobic exercise for moderate-to-severe obstructive sleep apnea in overweight or obese patients: a network meta-analysis
Abstract
Objective: Obstructive sleep apnea (OSA) is a highly prevalent sleep disorder strongly linked to obesity and substantially increases the risk of cardiovascular and metabolic diseases. Sodium-glucose cotransporter 2 (SGLT2) inhibitors, glucagon-like peptide-1 (GLP-1) receptor agonists, and aerobic exercise have shown potential in improving OSA through distinct metabolic and physiological mechanisms. However, direct comparative evidence of their efficacy remains limited. This network meta-analysis aimed to compare the effects of SGLT2 inhibitors, GLP-1 receptor agonists, and aerobic exercise on OSA severity in overweight or obese patients.
Methods: We searched four electronic databases, PubMed, EMBASE, the Cochrane Library, and Web of Science, for articles published before October 31, 2025, without language restrictions. The analysis primarily included randomized controlled trials (RCTs); a limited number of case-control studies were also incorporated due to the scarcity of direct comparative evidence. Primary efficacy outcomes were mean changes in the apnea-hypopnea index (AHI), body mass index (BMI), mean peripheral oxygen saturation (SpO2), and Epworth Sleepiness Scale (ESS) score. The certainty (confidence) of the evidence for every network estimate was appraised with the Confidence in Network Meta-Analysis (CINeMA) framework, which operationalizes the GRADE approach for network meta-analysis.
Results: A total of 15 studies (13 RCTs and 2 case-control studies) involving…
