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

unlabelledLittle is known about the effects of the pro-inflammatory hormone Angiotensin II (Ang II) in inflammatory bowel disease. The aim of this study was to evaluate the effect of valsartan (Diovan), an Ang II receptor antagonist, in two models of colitis.

methodsColitis was induced in Sprague-Dawley rats by administration of trinitrobenzene sulfonic acid (TNBS; 30 mg in 50% ETOH i.c.) or 5% Dextran Sulphate Sodium (DSS) in drinking water ad libitum for 5 days. Valsartan was administered orally in drinking water (160 mg/L) during thirty days prior to the induction of the colitis, and for 5 days after. All animals were evaluated for weight change, diarrhea, myeloperoxidase activity, macroscopic and microscopic damage. Cytokine levels in the colon were measured by ELISA, real-time RT-PCR and immunohistochemistry.

resultsIn the TNBS model, valsartan reduced the macroscopic damage score, significantly decreased the microscopic damage (p<0.01), and accelerated weight gain after colitis. In the DSS-colitis model, valsartan-treated animals had less diarrhea and microscopic damage. Valsartan reduced the protein levels of TGFbeta (p<0.05), and IL-18 in the TNBS model, and led to over expression of IL-10 mRNA in the DSS model.

conclusionThese data demonstrate a possible anti-inflammatory effect for valsartan in colitis.
