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

backgroundRemote limb ischemic pre-conditioning (RIPreC) can invoke potent renal protection. The involvement of oxidative stress and inflammatory pathways in renal ischemia/reperfusion injury (I/RI) was also confirmed. This study was designed to investigate the RIPreC effects on IRI-induced kidney dysfunction in rats through NFĸB/TNF-α/TGF-ꞵ/apelin signaling pathway.

methodsRenal I/RI was induced by occluding the kidney arteries for 45 min, then reperfusion for 24 h. Four similar cycles of left femoral artery ischemia (2 min)/reperfusion (3 min) before the onset of kidney ischemia were performed to create RIPreC. Animals were randomly divided into three groups: sham, I/R, and RIPreC + I/R. Following the reperfusion phase, urine and blood samples were taken, and the kidney was removed for functional, molecular, and histological examination.

resultsWhen compared to sham rats, renal IRI resulted in decreased creatinine clearance and increased sodium fractional excretion, lower antioxidant enzyme activities, higher malondialdehyde content and higher nuclear factor-kappa B (NF-κB), tumor necrosis factor-alpha (TNF-α), transforming growth factor-betta (TGF-β), and Apelin expression levels, and histologically damaged kidney tissue. All of the alterations, as mentioned earlier, were alleviated using the RIPreC treatment.

conclusionThus, RIPreC can protect against renal dysfunction after renal I/RI via modulation of the TNF-α/NF-κB/TGF-ꞵ/Apelin signaling pathway and strengthening the antioxidant defense system.
