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

backgroundMyenteric interneurones are involved in the reflexes that control the motility of the human colon.

aimsThe distribution of choline acetyltransferase (ChAT) and nitric oxide synthase (NOS) immunoreactivity in myenteric interneurones was investigated in this study.

methodsDiI (1,1'- didodecyl 3,3,3',3'-indocarbocyanine perchlorate) was applied to the myenteric plexus of the human colon followed by organotypic culture. Retrogradely labelled neurones, with projections longer than motor neurones (>10 mm), were studied to exclude motor neurone populations. ChAT and NOS immunoreactivity was then determined in the interneurones.

resultsWe found that 90% of interneurones projecting orally contained ChAT and none contained NOS. Ninety five per cent of descending interneurones were labelled with ChAT and/or NOS antisera; 46% contained NOS immunoreactivity alone, 20% contained ChAT immunoreactivity alone, and 29% contained both ChAT and NOS. Anally directed interneurones had significantly longer projections than orally projecting interneurones.

conclusionsNearly all interneurones contain either NOS or ChAT immunoreactivity. Orally projecting interneurones are of two types: 90% contain ChAT alone and the remainder contain immunoreactivity for neither ChAT nor NOS. There are three main types of anally projecting interneurones: the largest, which contains NOS but not ChAT, and the two smaller classes which contain ChAT and NOS, and CHAT alone.
