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

introductionDiabetes mellitus is the leading global cause of chronic kidney disease (CKD) and end-stage renal disease. Although cardiovascular outcomes have improved substantially, renal risk remains high. Glucagon-like peptide 1 (GLP-1) receptor agonists and the dual GLP-1/GIP agonist tirzepatide have demonstrated potential cardiorenal benefits, but renal evidence has not been systematically mapped across CKD stages and metabolic phenotypes. This scoping review aimed to identify and describe clinical evidence on renal outcomes associated with GLP-1-based therapies in adults with type 2 diabetes and/or overweight/obesity, with or without CKD.

methodsFollowing the Joanna Briggs Institute framework and PRISMA-ScR guidelines (protocol: OSF.IO/SZ87J), we searched PubMed, Embase, and CENTRAL from inception to October 2025. Eligible studies included phase 2-4 randomized controlled trials (RCTs), post hoc RCT analyses, and comparative observational studies reporting kidney outcomes. Data were charted using a structured extraction form with AI-assisted screening and manual validation. Risk of bias and certainty were appraised using RoB 2, ROBINS-I, and GRADE frameworks.

resultsOf 607 records identified, 35 studies met inclusion criteria. Randomized evidence supports renal benefits for semaglutide, dulaglutide, and liraglutide, including reductions in composite kidney outcomes and slower eGFR decline. Tirzepatide demonstrated consistent albuminuria reductions and attenuation of eGFR decline compared with insulin glargine. Efpeglenatide, cotadutide, exenatide, and lixisenatide showed class-consistent antiproteinuric effects. Observational data extended findings to real-world and advanced CKD populations. Across agents, renal benefits were partly independent of glycemic and weight effects.

conclusionGLP-1-based therapies demonstrate consistent renoprotective signals across CKD stages and metabolic phenotypes, particularly in type 2 diabetes. Evidence is strongest for semaglutide and dulaglutide, with emerging data for tirzepatide and other incretin-based agents. These findings provide a structured evidence map to inform future consensus and clinical decision-making.
