Sodium-glucose co-transporter 2 inhibition improves age-dependent kidney microvascular rarefaction.

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
introductionAging is associated with progressive loss of kidney function and vascular structure, with and without chronic kidney disease. However, the mechanisms driving kidney vascular aging and potential therapeutic interventions remain poorly understood.
methodsAfrican turquoise killifish (Nothobranchius furzeri), a naturally short-lived vertebrate, were used to investigate the natural course of kidney aging. We inhibited the sodium-glucose co-transporter 2 using dapagliflozin (SGLT2i) to test a potential therapeutic intervention. Histological, immunofluorescent, and 3D vascular imaging were used to evaluate glomerular, tubular, vascular and functional changes. Single nuclei transcriptomic profiling was performed on whole kidneys to identify age, sex and treatment-associated molecular signatures.
resultsAged killifish kidneys exhibited hallmark features of kidney aging, including glomerulosclerosis, tubular atrophy, and vascular rarefaction. Functional changes included increased proteinuria and altered tubular transporter function. Transcriptomic profiling revealed a metabolic shift from oxidative phosphorylation to glycolysis and upregulation of pro-inflammatory pathways. Aged vasculature displayed a marked reduction in tight junctions and cell-cell contacts. SGLT2i attenuated age-related vascular rarefaction, preserved functional capillary networks, reduced albuminuria, preserved a youthful transcriptional profile and enhanced key intercellular signaling pathways.
conclusionsOur study establishes the killifish as a translational model for investigating kidney vascular aging. SGLT2i preserves kidney microvascular structure and function, reduces proteinuria, and maintains a more youthful transcriptome. These results support a vascular-protective role of SGLT2i in mitigating age-related kidney deterioration.
