1 · What the graph read from it

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.

2 · The registry

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

Gastric plasmacytoma is rare in dogs, with only four previous reports providing limited descriptions of abdominal ultrasound (AUS) and computed tomography (CT) findings. This study presents the AUS and CT imaging features of two histopathologically suspected gastric plasmacytomas. Combining the four previous and two new cases, these tumors predominantly occurred in the greater curvature and pyloric antrum as solitary round masses connected to the submucosal or transmural layers. Pre- and post-contrast tissue attenuation (Hounsfield unit; HU) differences exceeded 40, with variable AUS echogenicity and echotexture. Imaging features may resemble those of spindle cell tumors, requiring histological and immunohistochemical examinations for definitive diagnosis.
