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

backgroundVasoactive intestinal peptide (VIP) has a number of important effects in intestinal physiology and pathology, including in ulcerative colitis (UC). The expression patterns of the predominant VIP receptor in the mucosa (the VPAC1 receptor) are unknown for the mucosa in UC. It is assumed that the sources of VIP in the intestine are the innervation and the inflammatory cells.

aimsThe VIP and VPAC1 receptor expression patterns in the epithelial layer of UC and non-UC patients were examined in the present study. The influence of marked inflammation of the mucosa was evaluated.

methodsSpecimens of the human colon, including the colon of UC patients, were examined concerning expressions of VIP and VPAC1 receptor, focusing on the epithelial layer. Immunohistochemistry and in situ hybridization were utilized.

resultsThere were VIP mRNA reactions and also marked VPAC1 receptor immunoreactions in the normal and slightly/moderately affected epithelium. VIP mRNA reactions were not detected and VPAC1 immunoreactions were minimal in response to marked mucosal derangement.

conclusionsThe findings suggest that there is a local production of VIP in the epithelial cells in normal and slightly/moderately inflamed mucosa but not in severely inflamed mucosa. Furthermore, a marked downregulation in VPAC1 receptor expressions occurs in the epithelium in severe UC. Based on the knowledge that VIP can have trophic, healing and anti-inflammatory effects, it is likely that the decrease in VIP mRNA and VPAC1 receptor reactions seen in severely affected mucosa in UC may be associated with adverse effects on intestinal function.
