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 57-year-old female patient with tuberous sclerosis and end-stage renal failure who had a history of diabetes mellitus and repeated renal hemorrhage after induction of dialysis underwent surgical nephrectomy. The renal tissue that caused the hemorrhage consisted of adipocytes, blood vessels, and smooth muscle cells, so angiomyolipoma was diagnosed. The cause of the hemorrhage was thought to be an abnormality in the vascular structure, i.e., disruption of the elastic plates that make up the vessel wall, and the presence of a hematoma in the same area. Diabetic nephropathy, which was observed in the atrophied native kidney, was presumed to be the cause of end-stage renal failure. Genetic analysis confirmed the presence of TSC2 mutation, which is linked to tuberous sclerosis, and HNF1B mutation, which is linked to diabetes. To our knowledge, this is the first report of a patient with HNF1B mutation who may have developed end-stage renal failure because of diabetic nephropathy and who also had histologic evidence of renal hemorrhage.
