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
Pelvic arteriovenous malformation compressing the prostate is a rare vascular anomaly mimicking benign prostatic hyperplasia. We reported a 59-year-old male with progressive lower urinary tract symptoms. Imaging revealed a 27 × 35 mm vascular mass compressing the prostate, consistent with a pelvic arteriovenous malformation supplied by the right prostatic artery and branches of the right internal iliac artery. Selective transarterial embolization using N-butyl-cyanoacrylate and lipiodol achieved complete occlusion. The patient was discharged the following day. At 1 month, the symptoms had resolved, and computed tomography demonstrated thrombosis and reduction of the venous sac. At 6 months, the patient remained asymptomatic, and ultrasound confirmed further regression without recurrence. This case highlights pelvic arteriovenous malformation as an uncommon cause of lower urinary tract symptoms and supports embolization as a safe, effective treatment.
