1 · What the graph read from it

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.

2 · The registry

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

The incretin hormone glucagon-like peptide-1 (GLP-1) exerts potent effects on glucose metabolism, prompting the development of therapeutic strategies that enhance activity of the GLP-1 receptor (GLP-1R) pathway. Inhibitors of dipeptidyl peptidase 4 (DPP-4) prolong the half-life of endogenous GLP-1 and typically achieve reductions in HbA1c of 0.5%-0.8%. However, large-scale cardiovascular (CV) outcomes trials (CVOTs) with DPP-4 inhibitors demonstrated CV safety but did not show a reduction in CV events. A second incretin-based therapeutic approach was the development of GLP-1R agonists (GLP-1RAs). Various GLP-1RAs, including liraglutide, semaglutide, and dulaglutide, demonstrated a reduction in CV outcomes in large CVOTs. Initially, these medications were only available as injectable agents for subcutaneous administration, but recent technological advancements have enabled the development of orally available GLP-1RAs. A third incretin-based approach is tirzepatide, a dual agonist of GLP-1R and glucose-dependent insulinotropic polypeptide receptor (GIPR), which achieves greater HbA1c reduction and weight loss compared with GLP-1RAs alone. Ongoing large-scale CVOTs will determine its effects on hard cardiovascular endpoints. This Review summarizes the effects of GLP-1 and GLP-1RAs in the CV system as well as clinical data of GLP-1RAs in individuals with CV disease or high CV risk.
