Study facts come from the paper. Population match, weight-loss explanation and study tier are our judgments, made against the reference group of healthy normal-weight adults aged 55–75.

Pooling three randomized trials in 828 adults with moderate-to-severe sleep apnea (two of tirzepatide, one of liraglutide), the drugs improved the Apnea/Hypopnea Index, weight and systolic blood pressure; diastolic blood pressure did not differ significantly. No significant serious adverse events were seen, but gastrointestinal side effects were more common. The evidence is limited to two published studies of three trials using different drugs, so firm conclusions cannot yet be drawn.

01cReview quality

How far the review's own results can be trusted

This record is a systematic review, so it is appraised with AMSTAR 2, which rates how far the review's own pooled results can be trusted. It does not grade the trials inside the review; those are appraised one by one.

On this scale High is the best rating. The levels run High, Moderate, Low, Critically low: Critically low confidence in the review is the worst rating a review can receive, and means it should not be relied on for an accurate summary. That is the opposite direction to the risk-of-bias scale used for single trials, where High is the worst.

Critically low confidence in the review · AMSTAR 2 · AI: two passes agreed

Why: 2 critical items fail: comprehensive literature search; list of excluded studies, with reasons.

What it is used for here: Used only to find trials. A review at this level does not supply a pooled result to any outcome in this collection; the trials it lists are appraised on their own.

Abstract

[BACKGROUND] Obstructive sleep apnea (OSA) is a common condition affecting around one billion people worldwide. Emerging evidence from recent studies suggests that Glucagon-like peptide 1 receptor (GLP-1) agonists may reduce OSA severity. Hence, this meta-analysis aims to evaluate the efficacy and safety of GLP-1 agonists in patients with OSA. [METHODS] Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we searched four electronic databases (PubMed, EMBASE, Cochrane Library, Scopus, and Web of Science) to identify eligible studies reported up to 24 June 2024. Using Review Manager software, we reported outcomes as risk ratios (RRs) or mean difference (MD) and confidence intervals (CIs). The protocol for this review has been registered and published in PROSPERO with the ID (CRD42024562853). [RESULTS] The meta-analysis included three randomized controlled trials with 828 patients. Pooled analysis of patients administered GLP-1 agonists or tirzepatide showed improvement in Apnea/Hypopnea Index (MD -16.57 events per hour, 95% CI [-27.41, -5.73], p = 0.003), weight reduction (MD -12.71%, 95% CI [-21.38, -4.03], p = 0.004), and systolic blood pressure (MD -4.93 mmHg,95% CI [-7.67, -2.19], p = 0.0004). Tirzepatide showed a reduction in high-sensitivity C-reactive protein (MD -0.89 mg/dl, 95% CI [-1.25, -0.54], p < 0.0001) and sleep apnea-specific hypoxic burden (MD -66.21%/min, 95% CI [-81.75, -50.67], p < 0.0001). Despite the heterogeneity observed in the AHI and weight, it was resolved, and the results were consistent. GLP-1 agonists/tirzepatide showed comparable outcomes concerning diastolic blood pressure (MD -1.34 mmHg, 95% CI [-2.80, 0.12], p = 0.07). No significant serious adverse events were observed for GLP-1 agonists/tirzepatide, but it was associated with a higher incidence of gastrointestinal adverse events. [CONCLUSION] GLP-1 agonists, including tirzepatide, improved Apnea/Hypopnea Index, weight, and systolic blood pressure in adults with moderate-to-severe OSA. However, the evidence remains limited to two published studies comprising three randomized controlled trials using different pharmacological agents. Consequently, further research is needed before firm conclusions can be drawn.
