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
backgroundPeritoneal metastasis occurs in 10%-45% of gastric cancer patients and significantly impacts prognosis and treatment decisions. Traditional computed tomography (CT) imaging has limited sensitivity (60%-80%) for detecting early peritoneal metastases, while laparoscopic exploration is invasive. Multiphase contrast-enhanced CT radiomics offers a non-invasive approach to improve preoperative prediction, yet most existing studies rely on single-phase analysis without fully exploiting multiphase data advantages.
aimTo construct a preoperative prediction model for gastric cancer peritoneal metastasis based on multiphase contrast-enhanced CT radiomics, compare the diagnostic efficacy between multiphase combined and single-phase analysis, and evaluate its clinical application value.
methodsA retrospective analysis was conducted on 200 pathologically confirmed gastric cancer patients from January 2020 to December 2024, all of whom underwent preoperative multiphase contrast-enhanced CT examination. Patients were randomly divided into training set (
resultsThe multiphase combined model achieved an area under the curve (AUC) of 0.876 (95% confidence interval: 0.783-0.941) in the validation set, with sensitivity of 81.0%, specificity of 84.6%, and accuracy of 83.3%, significantly superior to all single-phase models (
conclusionThe multiphase combined model based on multiphase contrast-enhanced CT radiomics can effectively predict gastric cancer peritoneal metastasis, with diagnostic performance significantly superior to single-phase models, providing a new non-invasive technical approach for individualized preoperative assessment of gastric cancer patients.
