Radiographic study of the anatomy and preliminary barium Gastrointestinal transit in the grasscutter (Thryonomys swinderianus, Temminck 1827).

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
purposeThis study describes the radioanatomy of the thoracic and abdominal viscera and to provide preliminary observations on a dynamic follow-up of barium transit through the gastrointestinal tract of the grasscutter using contrast radiography.
methodsThis study included three adult grasscutters, one male and two females, weighing an average of 3.10 ± 0.11 kg. All animals were imaged using an Italian digital camera and administered general anesthesia with xylazine and ketamine. Barium was put into the stomach; subsequently, X-rays were obtained from the front and side at set times.
resultsNormal radiographs showed that the grasscutter has a relatively small thorax with a proportionally large heart and a clearly visible trachea. The abdomen features a large cecum displacing the intestines, with the stomach and liver partially visible, while the kidneys were not seen. Dynamic barium follow-through revealed an increase in stomach size. The stomach and proximal small intestine emptied, with the first part of the small intestine filling with liquid after 30 min. After 1 h, both regions showed high radiographic density. Contrast reached the duodenum and jejunum at 2 and 3 h, respectively, and remained visible intermittently up to 18 h, indicating that grasscutters digest food more slowly than other species.
conclusionGrasscutters have slow gastrointestinal transit, with a transit time of over 24 h. These data can be used to diagnose intestinal obstruction in future studies on this species.
