Direct-stick embolization to treat hematochezia secondary to rectally metastatic sacral neuroblastoma.
Article in JPGN reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Neuroblastoma is a malignant tumor that is typically treated with a combination of surgery, radiation therapy, chemotherapy, and immunotherapy. However, minimally invasive embolization and chemoembolization present promising new treatment modalities. We present the case of a 6-year-old patient who initially presented with a massive lower GI bleed due to sacral neuroblastoma metastasis invading the rectum, that was managed via transarterial embolization and transrectal endoscopic-guided percutaneous nBCA embolization. There was significant tumoral supply from the posterior division of the internal iliac arteries treated with coil, liquid, and particle embolics. Subsequently, under endoscopic guidance, liquid embolization via direct puncture of the rectal metastasis was performed to manage any residual vascularity. Thereafter, the patient's lower GI bleed resolved. Direct puncture tumoral embolization offers a potentially highly effective, yet minimally invasive procedure that warrants further evaluation.
