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
backgroundEndoscopic submucosal dissection (ESD) is the standard treatment for early gastric neoplasms with low lymph node metastasis risk but is associated with notable bleeding complications, especially in high-risk patients. This study aims to evaluate the effectiveness of fibrin glue (FG) based strategies, with or without polyglycolic acid (PGA) sheets, in reducing postoperative hemorrhage.
methodsWe performed a systematic search of PubMed, Scopus, and the Web of Science from inception to December 2025. We included randomized controlled trials and observational studies comparing FG or FG plus PGA sheets versus standard care in adult gastric ESD patients. The primary outcome was delayed bleeding. Risk ratios (RRs) with 95% confidence intervals (CIs) were calculated using a random-effects model.
resultsThirteen studies involving an analytical cohort of 2,728 patients were included. The meta-analysis demonstrated that the intervention significantly reduced the risk of delayed bleeding (RR: 0.49; 95% CI: 0.28, 0.84; P = 0.01) and overall bleeding (RR: 0.52; 95% CI: 0.29, 0.91; P = 0.02) compared to standard care. Subgroup analysis revealed that the benefit was primarily driven by the combination of PGA sheets and FG (RR: 0.33; 95% CI: 0.17, 0.63; P < 0.001), while FG alone did not show a statistically significant reduction (RR: 0.62; P = 0.26). Similarly, symptomatic bleeding was significantly reduced only in the PGA + FG subgroup (RR: 0.25; P = 0.009). No significant differences were observed regarding acute bleeding (RR: 0.90; P = 0.81) or procedural perforation (RR: 1.09; P = 0.87).
conclusionThe combined application of PGA sheets and fibrin glue significantly reduces delayed hemorrhage after gastric ESD, likely due to a dual mechanism of mechanical shielding and biological stabilization. Fibrin glue alone does not consistently confer a protective benefit.
