Endoscopic ultrasound vascular parameter-based stratification for precise treatment of esophagogastric varices: a study on endoscopic ultrasound-guided tissue glue obliteration.
Article in Surgical endoscopy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesTo establish a hierarchical model based on endoscopic ultrasound (EUS) vascular parameters for predicting outcomes following EUS‑guided tissue glue obliteration in patients with esophagogastric varices (EGV), and to develop a precise treatment strategy.
methodsClinical and EUS data from 56 patients with F2-F3 EGV were retrospectively analyzed. Patients were classified into mild, moderate, and severe abnormality groups according to EUS‑derived vascular parameters. The primary outcome was rebleeding within 12 months. Multivariate logistic regression was used to identify independent risk factors. Internal validation was performed using bootstrap resampling and cross‑validation. The incremental predictive value of the stratification system was assessed using net reclassification improvement (NRI).
resultsThe overall rebleeding rate at 12 months was 25.00%, with a stepwise increase across the mild (5.56%), moderate (28.00%), and severe (46.15%) groups (P = 0.033). The variceal remission rate at 6 months showed a corresponding inverse gradient (83.33%, 64.00%, and 38.46%, respectively; P = 0.036). Portal vein flow velocity was identified as an independent protective factor against rebleeding (OR 0.60, 95% CI 0.39-0.84, P = 0.009). The stratification system demonstrated incremental predictive value beyond Child-Pugh, MELD, and Baveno criteria (NRI = 0.243, P < 0.001). Internal validation confirmed model stability without overfitting (optimism‑corrected AUC = 0.88).
conclusionsThe EUS‑based vascular parameter stratification system effectively predicts rebleeding risk and treatment outcomes in patients with EGV undergoing endoscopic therapy. Portal vein flow velocity is a key independent predictor. This stratification approach may serve as a practical tool to guide individualized treatment decisions, though external validation in larger cohorts is warranted.
