Effect of castration on pelvic neurons in the male pig.
Article in Histochemistry and cell biology, 2020. 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
The present study investigated the influence of castration performed at neonatal age on neuronal elements in the anterior pelvic ganglion of the male pig with immunohistochemistry and quantitative real-time PCR (qPCR). The ganglia were examined 3 and 6 months after surgery. In 3-month-old castrated pigs (3MCP) 74% of adrenergic and 31% of cholinergic neurons stained for caspase-3 (CASP-3), and much greater numbers of perikarya than in the control animals expressed CGRP, galanin (GAL) and VIP (peptides known to have neuroprotective properties). In 6-months-old castrated pigs (6MCP), an excessive loss (90%) of neurons and intraganglionic nerve fibres was found. The survived adrenergic and cholinergic neurons also expressed CASP-3, CGRP, GAL or VIP. The qPCR results corresponded with immunofluorescence findings. In 3MCP, genes for CASP-3 and CGRP were up-regulated, while the expression of those for DβH, VAChT, GAL, VIP and SP displayed statistically insignificant variations. In 6MCP, distinctly up-regulated were genes for CGRP, GAL, VIP, SP, DβH and VAChT, while the expression of casp3 gene was down-regulated. The study revealed for the first time the excessive loss of pelvic neurons following castration, and a realistic assumption is proposed, that the neurons died due to apoptosis triggered by androgen deprivation.
