Real-world cardiovascular effects of liraglutide: transportability analysis of the LEADER trial.
Article in medRxiv : the preprint server for health sciences, 2025. 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
Objective: To evaluate generalizability of the Liraglutide Effect and Action in Diabetes: Evaluation of Cardiovascular Outcome Results (LEADER) randomized clinical trial (RCT) - a cardiovascular outcomes study of the glucagon-like peptide-1 receptor agonist (GLP-1RA) liraglutide - to US Veterans Affairs Healthcare System (VA) patients with diabetes, a population at high cardiovascular disease risk lacking direct RCT evidence of GLP-1RA efficacy. Design: Transportability analysis that integrates real-world and RCT data to estimate the average treatment effect of liraglutide versus placebo had LEADER enrolled VA diabetes patients. Setting: Multi-national RCT and US VA. Participants: 9,336 LEADER participants and 357,075 VA users with diabetes from 2015-2023. Interventions: Liraglutide versus placebo. Main Outcomes and Measures: Risk differences (RD) in survival probabilities and hazard ratios (HR) of trial-adjudicated major adverse cardiovascular events (MACE) (composite of non-fatal myocardial infarction, non-fatal stroke, and cardiovascular mortality) and all-cause mortality, estimated with augmented inverse probability weighting after balancing baseline characteristics between LEADER participants and trial-eligible veterans using approximate balancing weights. Sensitivity analyses varied VA cohort composition and balancing variables. Results: Transported effects of liraglutide compared to placebo on MACE and all-cause mortality in veterans ("VA-weighted LEADER") consistently overlapped the treatment effects observed in LEADER: RD of 3-year MACE of 2.0% [95% CI 0.8, 3.2] in VA-weighted LEADER versus 1.6% [0.3, 2.9] in LEADER; MACE HR 0.74 [0.61, 0.90] in VA-weighted LEADER versus 0.87 [0.78, 0.97] in LEADER; RD of 3-year all-cause mortality of 1.5% [0.6, 2.4] in VA-weighted LEADER versus 0.9% [-0.09, 1.9] in LEADER; all-cause mortality HR 0.71 [0.57, 0.89] in VA-weighted LEADER versus 0.85 [0.74, 0.97] in LEADER. Results were robust to all sensitivity analyses. Conclusions: The benefits of liraglutide observed in LEADER generalized to veterans with diabetes - real-world evidence that can guide diabetes treatment decisions for a high-risk population underrepresented in RCTs and inform formulary policies for an integrated healthcare system.
