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
Background and Aims: Parastomal varices are an uncommon but serious cause of gastrointestinal bleeding in patients with portal hypertension. Conventional treatments include surgical revision or interventional radiology embolization, but these may not be feasible in advanced disease. Endoscopic ultrasound (EUS)-guided therapy offers a minimally invasive alternative. We describe 2 cases using EUS-guided coiling and combined thrombin/fibrinogen injection for parastomal variceal bleeding. Methods: Two patients with colorectal cancer and prior liver metastases developed recurrent bleeding from parastomal varices despite conservative or interventional radiology management. Feeding vessels were identified by EUS, accessed with a 19-gauge needle, and treated with intravascular coil embolization followed by injection of thrombin/fibrinogen. Results: Both procedures were technically successful without intraprocedural adverse effects. Doppler imaging confirmed near-complete obliteration of variceal flow. One patient remained free of recurrence, whereas the second required repeat treatment 2.5 months later, at which time cyanoacrylate glue was selected for definitive hemostasis. Conclusions: EUS-guided coiling with thrombin/fibrinogen injection appears to be a safe and effective option for achieving hemostasis in parastomal varices. Its minimally invasive nature and ability to directly target variceal inflow make it a promising alternative when conventional therapies are not feasible. Larger studies are needed to evaluate predictors of durable success and long-term outcomes.
