The guiding role of gastric filling ultrasonography in the diagnosis of stromal tumors and schwannomas-a retrospective study.

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: To differentiate the ultrasonographic characteristics of gastric stromal tumors (GSTs) and gastric schwannomas (GSs) identified via gastric filling ultrasonography and investigate the relationship between National Institutes of Health (NIH) risk stratification and the ultrasonographic imaging characteristics of GSTs. Methods: A retrospective analysis was performed on the clinical and ultrasonographic imaging data of 77 patients with GSTs and 16 with GSs who were evaluated between 2020 and 2025. Results: Statistically significant differences were observed in ultrasonographic findings, including tumor diameter, internal echo, morphology, and boundaries, between the GST and GS groups. Moreover, significant differences in the ultrasonographic features of GSTs were found across different NIH risk stratifications. Intermediate- or high-risk GSTs were closely associated with larger tumor diameters, more heterogeneous internal echoes, irregular shapes, indistinct boundaries, and abundant intratumoral blood flow. A scoring system was established based on significant ultrasonographic features derived from ROC curve analysis. Conclusions: Based on our analysis, gastric filling ultrasonography can be utilized to differentiate GSTs from GSs and predict the risk stratification of GSTs through an established ultrasound image scoring system. The clinical application of gastric filling ultrasonography may aid in the preoperative diagnosis of GSTs and the development of individualized treatment plans.
