Computed Tomographic Findings of Primary Hepatic Extraskeletal Osteosarcoma With Peritoneal Metastasis via Periportal Space in a Dog.
Article in Veterinary radiology & ultrasound : the official journal of the American College of Veterinary Radiology and the International Veterinary Radiology Association, 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 15-year-old castrated male Shih Tzu presented with anorexia and lethargy. Computed tomography (CT) revealed a hepatic mass with extensive central mineralization and an ill-defined hypoattenuating peripheral zone. The periportal halo sign extending to the lesser omentum was compatible with neoplastic infiltration of the periportal space, suggesting a potential metastatic pathway via this anatomical route. Whole-body CT excluded primary skeletal involvement, and histopathology confirmed extraskeletal osteosarcoma of hepatic origin. This case illustrates the value of CT in characterizing mineralized hepatic neoplasia and identifying potential routes of intra-abdominal dissemination.
