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
backgroundEarly screening, preoperative staging, and diagnosis of lymph node metastasis are crucial for improving the prognosis of gastric cancer (GC).
aimTo evaluate the diagnostic value of combined multidetector computed tomography (MDCT) and gastrointestinal endoscopy for GC screening, preoperative staging, and lymph node metastasis detection, thereby providing a reference for clinical diagnosis and treatment.
methodsIn this retrospective study clinical and imaging data of 134 patients with suspected GC who were admitted between January 2023 and October 2024 were initially reviewed. According to the inclusion and exclusion criteria, 102 patients were finally enrolled in the analysis. All enrolled patients had undergone both MDCT and gastrointestinal endoscopy examinations prior to surgical intervention. Preoperative clinical staging and lymph node metastasis findings were compared with pathological results.
resultsThe combined use of MDCT and gastrointestinal endoscopy demonstrated a sensitivity of 98.53%, specificity of 97.06%, accuracy of 98.04%, positive predictive value of 98.53%, and negative predictive value of 97.06% for diagnosing GC. These factors were all significantly higher than those of MDCT or endoscopy alone (
conclusionThe combined application of MDCT and gastrointestinal endoscopy enhanced diagnostic accuracy for GC, provided greater consistency in preoperative staging, and improved the detection of lymph node metastasis, thereby demonstrating significant clinical utility.
