Case Report: A case of gastric schwannoma diagnosed by dual-contrast-enhanced gastric ultrasound.
Article in Frontiers in oncology, 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
Gastric schwannoma (GS) is an infrequent, indolent, and predominantly benign neurogenic tumor, often identified incidentally due to the lack of specific symptoms in patients. During clinical evaluation, these lesions are commonly misidentified as gastric stromal tumors owing to the higher prevalence of the latter. In recent years, standard diagnostic techniques for GS have encompassed abdominal CT, abdominal MRI, gastroscopy, and gastric contrast-enhanced ultrasound. This report details a case of GS initially identified through gastric filling contrast-enhanced ultrasound (GF-CEUS) and intravenous contrast-enhanced ultrasound (IV-CEUS) with definitive diagnosis achieved via postoperative histopathological and immunohistochemical specimen analysis. Findings from this case underscore the substantial diagnostic value of using dual contrast-enhanced ultrasound for the preliminary identification of GS.
