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

backgroundIn earlier studies we found that a high-fat, high-energy diet (HFED) attenuates proteinuria, azotemia and lipid accumulation in the remnant kidney of rats subjected to 5/6 nephrectomy. This study was conducted to explore the mechanism of the salutary effect of HFED in association with moderate protein restriction in this model.

methodsThe 5/6 nephrectomized male rats were randomized to receive regular rat chow (CRF group, n = 6) or HFED diet (CRF + HFED, n = 7) for 12 weeks. Sham-operated rats served as controls (n = 6).

resultsThe CRF group exhibited azotemia, hypertension, proteinuria, diminished body weight, oxidative stress, glomerulosclerosis, tubulo-interstitial inflammation and upregulation of pro-oxidant [NAD(P)H oxidase], pro-inflammatory (NF-κB activation, increased MCP-1, lipoxygenase, ICAM-1, VCAM-1), pro-fibrotic (TGF-β, CTGF) and pro-apoptotic pathways (Bax, caspase-3) in the remnant kidney. Consumption of the HFED resulted in a 66% increment in lipid intake, 8% increment in carbohydrate intake and a 24% reduction in protein intake. The CRF + HFED group gained weight normally, had increments in leptin and adiponectin levels, and despite increments in plasma cholesterol and fatty acids, showed significant attenuation of oxidative stress, proteinuria and inflammation, and partial reversal of the remnant kidney upregulation of pro-oxidant, pro-inflammatory, pro-fibrotic and pro-apoptotic pathways.

conclusionConsumption of high-energy diet in association with mild protein restriction results in suppression of upregulated pathways that drive progression of renal injury in the remnant kidney model. These findings may have relevance in the management of chronic kidney disease in humans.
