Clinical Features and Factors Contributing to Preoperative Misdiagnosis of Gastric Gastrointestinal Stromal Tumors: A Retrospective Analysis of 27 Cases.

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: Gastrointestinal stromal tumors (GISTs) lack specific clinical manifestations and are challenging to distinguish from other gastric submucosal tumors (SMTs). This study is aimed at illustrating the atypical manifestations of non-GISTs mimicking gastric GISTs and determining whether objective preoperative factors can help differentiate gastric GISTs from non-GISTs in patients. Methods: We included 29 GIST patients and 27 patients preoperatively misdiagnosed with GIST located in the stomach. We compared demographic data and tumor characteristics based on endoscopic ultrasound (EUS) and computed tomography (CT) findings between GIST and non-GIST groups. Results: Clinical symptoms in the extragastric compressions group were significantly more common (100%) than in the GISTs group (35.7%) ( Conclusions: For gastric submucosal protuberant lesions, a comprehensive EUS and CT imaging examination is necessary for accurate diagnosis to avoid misdiagnosis and inappropriate treatment, which may affect patient prognosis.
