Adverse Cardiovascular Outcomes in Patients With Obstructive Sleep Apnea and Obesity: Metabolic Surgery vs Usual Care
Main finding · MACE, 10-year cumulative incidenceResult — go to the resultAdjusted hazard ratio 0.58 95% CI 0.48–0.71Authors' conclusion
Among patients with moderate-to-severe OSA and obesity, metabolic surgery, compared with nonsurgical management, was associated with a significantly lower risk of incident MACE and death.
