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

Renal angiomyolipomas (AMLs) may rupture and cause life-threatening hemorrhage. We report a man in his 40s with a ruptured giant renal AML who underwent emergent transarterial embolization after contrast-enhanced computed tomography demonstrated a pseudoaneurysm. Although initial hemostasis was achieved and he remained clinically stable, follow-up computed tomography performed 5 days later revealed a newly apparent 20-mm pseudoaneurysm arising from an alternative feeder, requiring repeat embolization. This case suggests that early postprocedural contrast-enhanced computed tomography may be useful in selected patients with ruptured giant or multifocal AMLs and high-risk vascular morphology.
