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

Iatrogenic cerebral amyloid angiopathy is a rare yet clinically relevant condition that may develop decades after cadaveric dura mater transplantation. We present the case of a 48-year-old man who experienced recurrent, bilateral, multilobar intracerebral hemorrhages approximately 40 years after childhood dura mater transplantation. Pathological examination confirmed amyloid β protein deposition around small cerebral blood vessels in the brain parenchyma. Genetic testing excluded mutations associated with hereditary cerebral amyloid angiopathy. According to the patient's operative record, at age 7 years, a left parietal bone tumor and the adjacent dura mater were removed, and a cadaveric dural patch was transplanted onto the intact brain surface. This case suggests that exogenous amyloid β protein can be transmitted through cadaveric dura mater, even when placed on intact brain tissue with preserved glymphatic and dural lymphatic drainage function, manifesting decades after transplantation.
