A new classification of gastric submucosal tumors under EUS based on blood flow signals.

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
Background and Objectives: Once gastrointestinal stromal tumor is suspected to have a malignant possibility, prompt medical intervention should be initiated. Neovascularization plays a significant role in the initiation and progressing of tumors. This study aims to investigate the morphology and distribution of blood vessels in submucosal tumors (SMTs), thereby providing theoretical support for vascular-targeted therapies. Methods: This study enrolled patients who underwent EUS at the First Medical Center of PLA General Hospital and stored images in the medical system, which were considered as SMTs with a definitive pathological diagnosis. The proportion of various blood flow signal under EUS was counted, and the correlation between blood flow signal and tumor pathology, ultrasonic features, location, and other factors was analyzed. Results: The overall occurrence rate of blood flow signal in SMTs was 69.4%. Appearance of blood flow signal of intratumor was 38.8%. Among them, spot-like, stripe-like, and patches-like were 26.5%, 10.2%, and 2.0%, respectively. As for peritumoral, the occurrence rate was 46.9% and was 36.7%, 6.1%, and 4.1% of the above 3 blood flow signals. The appearance of blood flow signals showed a significant correlation with the long diameter of the tumor ( Conclusions: We propose a new EUS classification of gastric SMTs based on blood flow morphology, revealing a significantly high occurrence rate of blood flow signals in these tumors.
