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
backgroundGlucagon-like peptide-1 receptor agonists (GLP-1 RAs) are increasingly used for diabetes and obesity. Yet, the role of comorbidities on adherence, and variability due to drug subtype or indication remains understudied.
objectiveStudy objective was to (a) evaluate association between baseline comorbidities and digestive system adverse events on first-year GLP-1 RA adherence and (b) assess how associations differ across GLP-1 RA subtypes and between patients with diabetes and obesity.
methodWe conducted a retrospective cohort study of adults with type 1 or type 2 or obesity initiating GLP-1 RAs between 2018 and 2023 using the University of California Health Data Warehouse. Primary outcome was first-year adherence association with baseline comorbidity and digestive system adverse event status. Adherence odds ratios based on exposure were estimated using regression. Analyses were stratified by indication and drug type.
resultAmong 69 049 adults who initiated a GLP-1 RAs between 2018 and 2023, 59.3% had diabetes and 74.4% had obesity. Among patients with diabetes, hypertensive disorder (OR: 1.06, 95% CI: 1.01-1.10), hyperlipidemia (OR: 1.17, 95% CI: 1.12-1.22), and chronic kidney disease (CKD) (OR: 1.14, 95% CI: 1.08-1.21) increased adherence likelihood. Among patients with obesity, hyperlipidemia (OR: 1.10, 95% CI: 1.05-1.15) and CKD (OR: 1.09, 95% CI: 1.02-1.16) were associated with increased adherence. In patients with diabetes, atherosclerotic cardiovascular disease (ASCVD) and digestive system adverse events reduced adherence likelihood (OR: 0.90, 95% CI: 0.86-0.95) and (OR: 0.94, 95% CI: 0.90-0.98), respectively. Results were similar for patients with obesity. Findings remained consistent overall in brand-specific analyses. CONCLUSION AND RELEVANCE: Comorbidities affected GLP-1 RA adherence with variation by drug and indication. Further research is needed to understand drivers of these patterns and how they may inform future strategies to support adherence.
