Prone transradial approach for radiofrequency ablation of hepatocellular carcinoma in the caudate lobe following TACE: a technical case report.

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
Radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) located in the caudate lobe is technically challenging because of the tumor's deep location and proximity to major vascular structures. A 71-year-old woman with a 2-cm HCC in segment I underwent conventional transcatheter arterial chemoembolization (TACE) via the femoral artery. Immediate RFA was not feasible because CT arterial portography revealed no safe puncture route due to surrounding vasculature. On the following day, angiography using a left transradial approach was performed with the patient in the prone position, enabling identification of a safe dorsal puncture path. After creation of an artificial pneumothorax, percutaneous CT-guided RFA was successfully completed without complications. Prone transradial angiography can facilitate safe RFA for hepatic tumors in anatomically challenging locations such as the caudate lobe. This approach may broaden treatment options when conventional supine access is not possible.
