1 · What the graph read from it

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.

2 · The registry

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

backgroundGastric variceal bleeding is a life-threatening complication of portal hypertension. Cyanoacrylate injection is the standard endoscopic treatment that carries a significant risk of ectopic embolization, particularly in patients with gastrorenal shunts. Adding endoscopic clips before injection may enhance safety and efficacy, yet evidence remains limited. This study evaluates the safety and effectiveness of clip-assisted cyanoacrylate injection (clip-ECI). METHODOLOGY: A systematic search was conducted on PubMed, Web of Science, CINAHL, Embase, Google Scholar, and the Cochrane Library on October 9, 2025, following the PRISMA 2020 guidelines. The protocol was registered on PROSPERO (CRD420251166002). The primary outcome was rebleeding. Secondary outcomes included technical success, adverse events, ectopic embolism, and procedure-related mortality. Meta-analysis was performed using R version 3.4.3 (R Core Team) with a random-effects model expressed as proportions and 95% confidence intervals (CIs).

resultsSix studies involving 465 participants treated with clip-ECI were included, four in the meta-analysis due to overlapping populations. Most participants were middle-aged males with cirrhosis from hepatitis B, presenting with GOV2 or IGV1 gastric varices; 41.7-100% had gastrorenal shunts. The pooled technical success rate was 99% (95% CI 0.97-1.0; p = 0.97; I

conclusionClip-ECI appears highly effective with low rebleeding and embolic complication rates, supporting its safety for gastric varices, particularly in patients with gastrorenal shunts. Large multicenter randomized trials are needed to strengthen these findings and establish clinical protocols.
