Semaglutide vs. liraglutide and incidence of diabetes and cardiovascular disease: A target trial emulation using real-world data.
Article in British journal of clinical pharmacology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
aimsThe glucagon-like peptide-1 receptor agonists (GLP-1 RAs) semaglutide and liraglutide are approved for chronic weight management. Both drugs also have favourable effects on the risk of developing diabetes and cardiovascular disease (CVD) compared with placebo, but their comparative effectiveness for these outcomes is unclear.
methodsWe employed an active comparator, new user design to emulate a target trial using data from MarketScan claims databases. Enrolees free of diabetes and CVD prescribed semaglutide or liraglutide during 2021-2023 were matched 1:1. Primary endpoints included incident diabetes and CVD (myocardial infarction, heart failure or stroke). We used Cox regression adjusted for a propensity score reflective of comorbidities and medication use.
resultsWe matched 57 456 GLP-1 RA users (mean age 45; 83% female). Over 1-year mean follow-up, we observed 1104 diabetes events and 57 CVD events. After regression adjustment, semaglutide users had 12% lower risk of diabetes (hazard ratio [HR]: 0.88; 95% CI: 0.78, 0.99). For this endpoint, the proportional hazards assumption was violated (p < .0001), so results were stratified by follow-up time. During the first 6 months of follow-up, semaglutide use was not associated with risk of diabetes compared with liraglutide use (HR: 0.99 [0.82-1.18]), but a significant association was present thereafter (HR: 0.80 [0.68, 0.94]). We did not detect a difference in risk of CVD events (HR: 1.25 [0.74-2.11]).
conclusionsIn this real-world study, semaglutide users had lower risk of incident diabetes compared with liraglutide users. Additional research is needed to elucidate comparative effectiveness of these drugs for cardiovascular risk.
