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/

aimsThe rat has been the most used experimental animal for studies of cardiovascular and kidney diseases. However, it is notable that there is increasing importance placed on the use of the mouse model to increase understanding of these pathophysiologies. The aim of the present study was to induce chronic kidney disease in a mouse model and to evaluate the resulting changes in blood pressure (BP) and in renal morphology and function.

methodsAdult male C57BL/6 mice underwent 5/6 nephrectomy (5/6 Nx) or a sham operation (Sham). Two weeks later, conscious animals were subjected to a 24-hour urine collection and to a direct measurement of BP.

resultsCompared to Sham animals, 5/6 Nx mice showed reduced creatinine clearance (3-fold, p<0.01), proteinuria (1.5-fold, p<0.01) and uremia (4-fold, p<0.01), as well as high blood pressure (~20%, p<0.01). 5/6 Nx animals showed increases in the 24 h urine excretion of Na(+) (2-fold, p<005), K(+) (~2-fold, <0.01) and Ca(2+) (~12-fold). Kidney histology of 5/6 Nx mice also demonstrated glomerular hypertrophy (1.5-fold, p<0.05), mesangial expansion (~40%, p<0.01) and increased glomerular collagen deposition (~30%, p<0.05).

conclusionInduction of 5/6 nephrectomy in mice for two weeks leads to systemic arterial hypertension and to functional and morphological damage of the remnant kidney, which are considered the main characteristics of chronic kidney disease.
