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

An 83-year-old male who underwent left nephrectomy about 40 years ago presented with a fatty mass in the retroperitoneum on CT images. The patient was diagnosed with extra-renal retroperitoneal angiomyolipoma (AML) through CT-guided retroperitoneal biopsy. Based on additional tests, the patient was also diagnosed with tuberous sclerosis complex (TSC). Given the substantial size (over 4 cm) of the tumor and the presence of an aneurysm, transcatheter arterial embolization (TAE) was performed to prevent rupture. Transcatheter embolization of the left testicular artery, left inferior phrenic artery, and left first lumbar artery did not result in any major complications. In addition, the tumor size had significantly reduced 12 months after TAE, and no aneurysm was detected. Extra-renal retroperitoneal AMLs associated with TSC are extremely rare, and may involve more feeding arteries than renal AMLs. Given the challenges in performing emergency TAE for ruptured extra-renal retroperitoneal AMLs, it is preferable to prevent rupture using this approach.
