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
backgroundPost-endoscopic submucosal dissection electrocoagulation syndrome (PEECS) is a critical complication following endoscopic resection of gastric gastrointestinal stromal tumors (gGISTs). However, validated tools for predicting PEECS risk remain limited. This study aimed to develop and validate a scoring system to stratify PEECS risk in patients undergoing endoscopic submucosal dissection (ESD).
methodsA multicenter retrospective analysis included 618 patients with gGISTs treated with ESD between January 2011 and December 2024. Cohorts were stratified into a training cohort (TC, N = 346), an internal validation cohort (IVC, N = 148), and an external validation cohort (EVC, N = 124). Univariate and multivariate logistic regression analyses identified independent risk factors, which were weighted by regression coefficients to construct a scoring system. Performance metrics, including area under the curve (AUC), sensitivity, specificity, and predictive values, were evaluated across cohorts.
resultsPEECS occurred in 89 cases (14.4%). Multivariate analysis confirmed that circumferential tumor location, severe intraoperative bleeding, and prolonged procedure time as independent predictors. The scoring system assigned points as follows: anterior wall location (2 points), occurrence of severe intraoperative bleeding (3 points), and procedure time ≥ 60 min (1 point). The scoring system demonstrated robust discrimination, with AUCs of 0.838 (IVC) and 0.842 (EVC), and high negative predictive values (NPV: 95.6% and 92.1%, respectively). PEECS incidence escalated with risk strata: low-risk (score 0-1: 4.8% TC, 4.4% IVC, 5.5% EVC), intermediate-risk (score 2-3: 21.6% TC, 21.6% IVC, 25.0% EVC), and high-risk (score 4-6: 92.3% TC, 100.0% IVC/EVC).
conclusionThis innovative scoring system, integrating tumor location, intraoperative bleeding, and procedure duration, provides a practical tool for predicting PEECS risk. Its robust validation across cohorts underscores its potential utility in guiding perioperative management and improving patient outcomes. Clinicians may use this tool to identify high-risk patients and implement preventive strategies proactively.
