A method for intracerebroventricular cannulation of young broiler chicks.
Article in MethodsX, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 site-specific administration of neuroactive substances or pharmacological agents is a routine practice in neurological studies. To facilitate chronic treatments intercranial cannulae are often implanted in the skull. These surgical procedures are widely described and well-documented for rodents, as the most common animal model, and even refined over the years. However, precise descriptions of proper procedure for third ventricle cannulation in young broiler chicks is not readily available. This absence is surprising, as chicken models are often used in the investigation of physiological control of the metabolism and ingestion. Furthermore, as a commercial animal, there is also a particular interest in elucidating the central regulation of feed intake and metabolism to optimize feeding and living conditions for broilers. The brain nuclei that serve as the regulatory centers of feeding and metabolism are the arcuate nucleus, the ventromedial hypothalamic nucleus, and the lateral hypothalamus, which are all located near the third ventricle. Here, we provide a full protocol for intracerebroventricular (i.c.v.) cannulation of 7-day old broiler chicks, as well as a review of some of the advances made in rodent i.c.v. cannulations and whether these advances are applicable to cannulations in chickens. Using the surgical procedure described here, we were able to achieve a success rate of proper implantation of 88%, with a mortality rate of less than 1% (
