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 AND

aimsShort-chain fatty acids (SCFAs), such as acetate, propionate and butyrate, are the major by-product of bacterial fermentation of dietary fiber in the colon. In this report, we investigated how SCFAs modulate matrix metalloproteinase (MMP) secretion from human colonic subepithelial myofibroblasts (SEMFs). MATERIALS AND

methodsSEMFs were identified by expression of alpha-smooth muscle actin and vimentin. Cytokine-induced MMP-1 and MMP-3 levels were determined by enzyme-linked immunosorbent assay. Cytokine-induced MMP mRNA expression was analyzed by RT-PCR and real-time PCR methods.

resultsAcetate had no effect on MMP secretion. Propionate and butyrate significantly attenuated IL-1 beta- and TNF-alpha-induced MMP-1 and MMP-3 secretion. Similar responses were also observed at the mRNA levels. Propionate and butyrate did not modulate IL-1 beta- and TNF-alpha-induced activation of mitogen-activated protein kinases (MAPKs), which play a crucial role in MMP induction. Trichostatin A, a histone-deacetylase inhibitor, reduced IL-1 beta-induced MMP-1 and MMP-3 mRNA expression, and suppressed TNF-alpha-induced MMP-3 mRNA expression.

conclusionSCFAs play an anti-inflammatory role through suppression of MMP secretion in the colon. Inhibitory effects of SCFAs on MMP secretion might be associated with their action of histone hyperacetylation.
