Vasoactive intestinal polypeptide and nitric oxide synthase distribution in the enteric plexuses of the human colon: an histochemical study and quantitative analysis.
Article in Histochemistry and cell biology, 1995. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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
unlabelledVasoactive intestinal polypeptide (VIP) and nitric oxide synthase (NOS) positive innervation patterns were immunohistochemically and statistically evaluated in the human colon. Specimens from the right colon (cecum, ascending and right transverse colon) and left colon (left transverse and descending colon) were obtained surgically, fixed either in paraformaldehyde or in Carnoy's or in Bouin's and paraffin embedded. Sections were stained with hematoxylin-eosin, toluidine blue, cresyl violet, neuron-specific enolase, anti-VIP, and anti-NOS. The same results were obtained regardless of the fixative used. Enolase-positive, VIP-positive, and NOS-positive cells were occasionally found within the circular muscle and interpreted as neurons. VIP-positive nerve fibers were evenly distributed within the circular muscle while NOS-positive ones were lacking in its inner portion. The left colon was richer in neurons than the right colon, at both plexuses. VIP- and NOS-positive neuron densities were higher at the left than at the right colon, whereas at all colonic levels VIP-positive neuron percentages at both plexuses and NOS-positive ones at the myenteric plexus were similar. At the submucous plexus the NOS-positive neuron percentage was lower than that of the VIP-positive one. IN
conclusion(a) the right colon contains a lower number of neurons and of VIP- and NOS-positive ones than the left colon, and (b) VIP- and NOS-positive fibers are differently distributed in the inner and outer portions of the circular muscle.
