What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveGlucagon-like peptide-1 receptor agonists (GLP-1RAs) are increasingly prescribed for type 2 diabetes mellitus and obesity. Their metabolic, anti-inflammatory, and osteogenic effects raise important questions regarding their influence on spinal fusion. To date, no systematic review has specifically investigated how GLP-1RAs influence outcomes following the common anterior cervical discectomy and fusion (ACDF). This study aimed to evaluate the association between perioperative GLP-1RA use and outcomes following ACDF.
methodsFollowing PRISMA guidelines, MEDLINE, Embase, PubMed, and the Cochrane Library were searched from inception to February 2026 for studies evaluating GLP-1RA exposure in the context of ACDF. Eligible studies included human observational cohort studies. Data were extracted independently by two reviewers.
resultsEight retrospective cohort studies analysing 311,402 ACDF patients were included, of whom 8,182 were GLP-1RA users matched to non-users. Random-effects meta-analysis demonstrated significantly lower odds of pseudarthrosis among GLP-1RA users at 6 months (OR = 0.60, 95% CI: 0.52 to 0.71; I² = 16.6%), 12 months (OR = 0.62, 95% CI: 0.53 to 0.73; I² = 39.1%), and 24 months (OR = 0.67, 95% CI: 0.57 to 0.79; I² = 34.9%). Findings for reoperation, dysphagia, deep vein thrombosis, and readmission were heterogeneous and inconsistent across studies.
conclusionPerioperative GLP-1RA use was associated with lower odds of pseudarthrosis. However, evidence regarding other postoperative complications remains inconclusive. Future prospective studies are required to further elucidate the impact of GLP-1RA use on ACDF outcomes. LEVEL OF EVIDENCE: Level III, therapeutic study.
