A rare case of caval foramen hernia involving the small intestines and hepatic lobes in a dog.
Article in The Journal of veterinary medical science, 2026. 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
A 6-year-old intact male French Bulldog presented with a 5-day history of vomiting. Radiographs revealed a round soft tissue mass in the right caudal thoracic cavity with tubular structures suggestive of small intestinal herniation through the diaphragm. Ultrasonography confirmed herniation of fluid-filled small intestinal loops and hepatic lobes positioned cranial to the diaphragm. Computed tomography (CT) revealed herniation of the involved organs through a dilated caval foramen and secondary caudal vena cava compression, consistent with Budd-Chiari-like syndrome resulting from venous outflow obstruction. Laparotomy confirmed strangulation of herniated organs, necessitating partial hepatectomy and segmental enterectomy. This case highlights the potential for small intestinal involvement in caval foramen hernia and underscores the diagnostic value of CT in assessing associated vascular compromise.
