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

We present a rare case of retroperitoneal calciphylaxis in a 63-year-old woman with end-stage renal disease secondary to hypertension. The disease involved bilateral retroperitoneum and was incidentally found on CT imaging performed for renal transplant evaluation. Imaging revealed diffuse soft tissue hyperattenuation, calcified nodules and cortical calcifications. Subsequent biopsy of the perinephric fat demonstrated fat necrosis and vascular wall calcification, consistent with calciphylaxis. The patient was medically cleared for renal transplantation and has shown improved kidney function on follow-up. While both cutaneous and visceral calciphylaxis typically carry poor prognoses, this case represents an indolent visceral variant discovered in the absence of cutaneous or systemic complications.
