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

Background: Coronary artery disease (CAD) imposes marked morbidity on patients, with many afflicted with debilitating residual symptoms despite optimal application of the available medical and surgical options. Glucagon-like peptide-1 (GLP-1) agonists have emerged from the resultant search for adjuncts as promising cardioprotective candidates in clinical trials. Aims: We have previously characterized the augmented myocardial functional response to GLP-1 agonism; in this experiment, we aim to elucidate the molecular basis of this augmentation using highly sensitive proteomic analysis. Methods: Yorkshire swine underwent surgical induction of CAD-associated ischemic cardiomyopathy through ameroid constrictor placement. Postoperatively, all were allocated either to receive semaglutide (n=6), or no drug (n=10) for 5 weeks, whereupon animals underwent myocardial resection and sectioning. The most ischemic ventricular sections were identified, from which tissue aliquots were fractionated using high-performance liquid chromatography and analyzed using mass spectrometry. Results: There were 594 upregulated and 90 downregulated proteins identified in the semaglutide cohort compared with control cohort. Enrichment analysis revealed marked upregulation of multiple central metabolic pathways, including the glycolytic and tricarboxylic acid cycle pathways. The significantly downregulated proteomic fraction was found within pathways relevant to the induction of dilated and hypertrophic cardiomyopathy. Conclusions: Myocardial sections taken from semaglutide-treated animals exhibited a striking and multifaceted increase in metabolic flexibility. This result implicates enhanced resilience against the energetic strain imposed by ischemic disease as a mechanistic account of GLP-1-mediated cardioprotection.
