Tumor-Stroma Ratio is a Critical Indicator of Peritoneal Metastasis in Gastric Cancer.

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: This study aims to investigate the correlation between the tumor-stroma ratio (TSR) and peritoneal metastasis (PM) in gastric cancer (GC) and constructs a diagnostic model based on preoperative examination data. Methods: To determine the feasibility of obtaining TSR in GC patients through preoperative examinations, the consistency of TSR between endoscopic biopsy tissues and postoperative histopathological tissues was evaluated. Additionally, the correlation between TSR and PM in GC was analyzed using Gene Expression Omnibus (GEO) datasets. To validate TSR's clinical potential in diagnosing PM, 640 GC patients from two medical centers were enrolled. A training cohort of 330 patients evaluated TSR and synchronous PM correlation, and a validation cohort of 310 patients was used. An additional cohort of 510 patients was established to investigate TSR and metachronous PM. A diagnostic model based on preoperative data was developed and a nomogram constructed. Results: The TSR shows good consistency between endoscopic biopsy tissues and postoperative histopathological tissues. A significant correlation between TSR and PM was observed. The TSR-based model, combined with CA125, CA724 and Borrmann type, exhibited strong diagnostic effectiveness and considerable predictive efficacy, with an Area Under the Curve (AUC) of 0.85 in the training cohort, 0.73 in the external validation cohort, and 0.72 in the metachronous PM cohort. Conclusion: The TSR emerges as a crucial marker for PM in GC, with the developed model, based on TSR and preoperative examination data, demonstrating substantial diagnostic and predictive capabilities.
