GLP-1 receptor agonists and outcomes after cervical spine fusion: a systematic review, meta-analysis, and evidence map of real-world evidence.
Editor's note
The headline here is the disagreement, not a direction. With an overall I-squared of 97 percent and estimates running from OR 0.52 to OR 4.79 depending on procedure and database, the pooled number is not interpretable and the authors sensibly decline to draw a class-wide conclusion. All twelve inputs are retrospective claims-database cohorts with overlapping populations, so confounding by indication and double-counting are live concerns even with the prespecified de-duplication. The semaglutide posterior-fusion signal is worth watching but is a single cohort and hypothesis-generating only.
Plain-language abstract
This meta-analysis pooled twelve retrospective databases studies on whether people taking GLP-1 drugs fare differently after cervical spine fusion surgery. Results split by procedure: one large dataset showed lower odds of failed fusion in anterior surgery, another showed no difference, and a semaglutide-specific posterior-fusion cohort showed substantially higher two-year failed-fusion odds. Overall heterogeneity was extreme.
