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

backgroundTransarterial embolization (TAE) is an established therapeutic option for non-variceal gastrointestinal bleeding (GIB), but standardized criteria for patient selection and predictors of treatment outcomes remain limited. This study aimed to evaluate clinical outcomes after TAE and identify factors associated with treatment failure and 30-day mortality.

methodsWe retrospectively reviewed all TAE procedures performed for nonvariceal GIB at Semmelweis University between May 2022 and July 2025. Clinical, laboratory, and procedural parameters were collected, including bleeding location, comorbidity burden, antithrombotic therapy, transfusion requirements, vasopressor or inotropic support, and embolization technique. Predictors of clinical failure (rebleeding within 30 days) and 30-day mortality were assessed using multivariable logistic regression.

resultsA total of 111 embolizations were performed in 100 patients. Technical success was 100%, and clinical success was achieved in 82% of patients. The 30-day all-cause mortality rate was 26%, with disease-specific mortality at 15%. Complications occurred in 4% of cases. Vasopressor or inotropic therapy and antithrombotic use were independent predictors of clinical failure. Vasopressor requirement and higher Charlson Comorbidity Index (CCI) scores were significantly associated with 30-day mortality. Empiric embolization was associated with a lower likelihood of rebleeding but did not influence mortality.

conclusionsTAE provided high technical success and favorable overall outcomes with a low complication rate in the management of nonvariceal GIB. Vasopressor requirement was the strongest predictor of both rebleeding and mortality, likely reflecting the underlying severity of shock physiology rather than the direct effects of vasopressor therapy. These results highlight the need for further prospective studies to guide management strategies in hemodynamically unstable patients requiring vasopressor support.
