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

backgroundRC-3095, a synthetic gastrin-releasing peptide (GRP) antagonist, has been identified as a candidate compound for the treatment of tumor necrosis factor (TNF)-dependent chronic inflammatory conditions.

aimThe aim of this study was to evaluate the effects of RC-3095 in a rat model of ulcerative colitis.

methodsNinety Wistar rats were included in the study. Colitis was induced by a single intracolonic application of acetic acid. Rats were divided into three groups of treatment: subcutaneous RC-3095, intracolonic mesalazine, and subcutaneous dexamethasone. Additionally, there was a fourth group of animals submitted to induction of colitis without receiving any form of treatment, and a fifth group in which no colitis was induced. Seventy-two hours after instillation of acetic acid, the animals were killed and the following parameters were assessed: morphological score of damage, histological score of colonic inflammation, and immunohistochemical expression of TNF-alpha and interleukin (IL)-1beta.

resultsRC-3095 was the only treatment to significantly reduce macroscopic and microscopic scores of inflammation as compared with the animals from the non-treated colitis group. RC-3095 also significantly reduced the colonic expression of TNF-alpha, but not the expression of IL-1beta.

conclusionsRC-3095 reduced the colitis severity in a well-established experimental model of IBD. The anti-inflammatory activity of this compound was associated with a reduction in the colonic expression of TNF-alpha. These results suggest that interference with GRP pathway might represent a potential new strategy for the treatment of ulcerative colitis that deserves further investigational studies.
