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

Short-chain fatty acids (SCFAs), 2-4 carbon monocarboxylates including acetate, propionate and butyrate, are known to have a variety of physiological and pathophysiological effects on the intestine. Previously, we reported that the SCFA receptor, G-protein coupled receptor 43 (GPR43), is expressed by enteroendocrine and mucosal mast cells in the rat intestine. In the present study, expression and localization of GPR43 were investigated in the human large intestine. Gene and protein expression of GPR43 in the human ascending colon was analyzed by reverse transcriptase/polymerase chain reaction and Western blotting, respectively. In addition, localization of GPR43 was investigated by immunohistochemistry. In RT-PCR analysis, GPR43 mRNA was detected in whole wall mRNA samples. Western blotting analysis revealed the expression of GPR43 protein in whole wall and scraped mucosa protein samples, but not in muscle or submucosa. GPR43 immunoreactivity was observed in the intracellularly in enterocytes and in the peptide YY-immunoreactive enteroendocrine cells. These results indicate that the short chain fatty acid receptor, GPR43 is expressed by enteroendocrine L cells containing peptide YY in the human large intestine.
