Endoscopic variceal ligation versus cyanoacrylate injection for acute variceal bleeding from the cardia to the lesser curvature.
Article in Journal of the Chinese Medical Association : JCMA, 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
backgroundCurrent guidelines recommend endoscopic variceal ligation (EVL) and endoscopic cyanoacrylate injection (ECI) for esophageal and fundal variceal bleeding, respectively. However, the optimal strategy for treating acute variceal bleeding (AVB) from the cardia to the lesser curvature remains undefined. This study compared the efficacy of EVL and ECI for AVB in this region.
methodsWe retrospectively analyzed patients with AVB from the cardia to the lesser curvature treated with EVL or ECI. Varices were classified as type 1 gastroesophageal varices-cardiac varices (GOV1-CVs; 0-2 cm below the gastroesophageal junction) or conventional GOV1s (2-5 cm below). Outcomes, including 5-day treatment failure, 6-week rebleeding, and 6-week survival, were compared using Kaplan-Meier analysis. Independent predictors of rebleeding and mortality were identified via Cox regression and subgroup analyses by variceal location.
resultsWe enrolled 129 patients (EVL: 59; ECI: 70) between 2006 and 2024. Both modalities achieved high hemostasis rates, with no significant differences in 5-day treatment failure (3.4% vs 4.3%; p = 1.000), 6-week rebleeding (10.2% vs 12.9%; p = 0.630), or 6-week survival (76.3% vs 77.1%; p = 0.956). On multivariable analysis, portal vein thrombosis (hazard ratio [HR]: 5.4; p = 0.020) and clinically significant bleeding (HR: 4.4; p = 0.016) predicted 6-week rebleeding, whereas Child-Pugh class C (HR: 4.3; p < 0.001) and creatinine >1.3 mg/dL (HR: 2.5; p = 0.024) predicted 6-week mortality. EVL demonstrated lower 6-week rebleeding than ECI for GOV1-CVs (9.8% vs 40.0%, p = 0.011), but not GOV1s ( p = 0.408). In the GOV1-CVs subgroup, EVL (HR: 0.2; p = 0.030) was the only independent predictor of rebleeding.
conclusionEVL and ECI demonstrated comparable efficacy for AVB from the cardia to the lesser curvature. Notably, EVL is superior to ECI in reducing 6-week rebleeding in GOV1-CVs, supporting EVL as the preferred approach and underscoring the importance of precise variceal classification.
