  1. 01HumanRandomized controlled trialEfficacy outcome

    In patients with obstructive sleep apnea, liraglutide alone gave a smaller reduction in apnea-hypopnea index (mean difference -12 events/h) than CPAP alone or the combination.

    In plain wordsIn people with sleep apnea, liraglutide alone reduced breathing interruptions less than CPAP alone or the combination did.

    Summary
    CPAP alone and in combination resulted in greater reduction in apnea-hypopnea index than Lir alone (mean difference, -45 and -43 events/h, respectively, vs. -12 events/h; P < 0.05).

    Summary
    Both Lir and combination treatment led to significant weight loss, but only CPAP alone resulted in significant decrease in vascular inflammation (aortic wall target-to-background ratio from 2.03 ± 0.34 to 1.84 ± 0.43; P = 0.010), associated with an improvement in endothelial function and a de…
