Histological and histochemical characteristics of the esophagus in local breed donkey (

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
Objective: Certain advantages of donkeys are still not listed as for other equine species. Moreover, donkeys lack comprehensive scientific studies. The present study examines the histological architecture and histochemical characteristics of the esophagus in the Iraqi local breed donkey ( Materials and Methods: Eight esophagus samples were collected from a local breed donkey. Tissue specimens (~1 cm Results: The esophagus of the local breed donkey had folded mucosa wrapped by thin non-keratinized stratified squamous epithelium. The heights of epithelia of the cervical and thoracic regions of the esophagus were significantly higher than that of the abdominal regions. The lamina propria consisted of dense fibrous tissue that appeared thickest in the thoracic and abdominal regions of the esophagus. The muscularis mucosa disappears at the cervical region, while the thoracic and abdominal regions of the esophagus contain thick, scattered, interrupted bundles of smooth muscle fibers. Tunica submucosa was very thick at the thoracic and abdominal regions of the esophagus, composed of loose connective tissue filled with compound tubular mucoserous esophageal glands. Using a combined AB-PAS stain, mucous alveoli within the esophageal glands indicated strong acidic mucopolysaccharide. Tunica muscularis of the cervical and thoracic regions was built up by striated muscle fibers and turned into smooth type at the abdominal region of the esophagus. Conclusion: The esophagus of the local breed donkey shows considerable histological similarities with the other mammals that make this species reliable as an experimental model of digestive tissue.
