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

A 66-year-old woman with a solitary right kidney with renal artery stenosis and a 5.0-cm abdominal aortic aneurysm underwent renal artery stenting followed by endovascular aortic aneurysm repair endovascular aneurysm repair 1 month later. She developed rapidly progressive renal failure and recurrent hypertension despite a patent renal stent. A renal biopsy revealed cholesterol crystal emboli with focal segmental glomerulosclerosis, supporting the diagnosis of atheroembolic kidney disease. High-dose methylprednisolone followed by a 5-week prednisone taper and temporary hemodialysis led to dialysis independence and blood pressure control within 2 months. Biopsy-driven diagnosis, hemodialysis, and pulse corticosteroid therapy may reverse atheroembolic renal injury, especially in vulnerable patients with a single kidney.
